+examples
+^^^^^^^^
+
+  appconfig and CONFIG_APPS
+  
+    The examples directory contains several sample applications that
+    can be linked with NuttX.  The specific example is selected in the
+    configs/<board-name>/appconfig file via the CONFIGURED_APPS setting.
+    This setting provides the path to the directory containing the
+    application Makefile (this path is a relative to the apps/ top-
+    level directory).  For example, 
+
+      CONFIGURE_APPS += examples/ostest
+
+    Selects the examples/ostest example.
+
+  Built-In functions
+
+    Some of the examples may be built as "built-in" functions that
+    can be executed at run time (rather than as NuttX "main" programs).
+    These "built-in" examples can be also be executed from the NuttShell
+    (NSH) command line.  In order to configure these built-in  NSH
+    functions, you have to set up the following:
+
+    - CONFIG_NSH_BUILTIN_APPS - Enable support for external registered,
+      "named" applications that can be executed from the NSH
+      command line (see apps/README.txt for more information).
+    - CONFIG_EXAMPLES_XYZ_BUILTIN -- Build the XYZ example as a "built-in"
+      that can be executed from the NSH command line (where XYZ is
+      the specific example.  See the following for examples that
+      support this option).
+
+examples/adc
+^^^^^^^^^^^^
+
+  A mindlessly simple test of an ADC devices.  It simply reads from the
+  ADC device and dumps the data to the console forever.
+
+  This test depends on these specific ADC/NSH configurations settings (your
+  specific ADC settings might require additional settings).
+
+    CONFIG_ADC - Enabled ADC support
+    CONFIG_NSH_BUILTIN_APPS - Build the ADC test as an NSH built-in function.
+      Default: Built as a standalone problem
+
+  Specific configuration options for this example include:
+ 
+    CONFIG_EXAMPLES_ADC_DEVPATH - The default path to the ADC device. Default: /dev/adc0
+    CONFIG_EXAMPLES_ADC_NSAMPLES - If CONFIG_NSH_BUILTIN_APPS
+      is defined, then the number of samples is provided on the command line
+      and this value is ignored.  Otherwise, this number of samples is
+      collected and the program terminates.  Default:  Samples are collected
+      indefinitely.
+    CONFIG_EXAMPLES_ADC_GROUPSIZE - The number of samples to read at once.
+      Default: 4
+
+examples/buttons
+^^^^^^^^^^^^^^^^
+
+  This is a simple configuration that may be used to test the board-
+  specific button interfaces.  Configuration options:
+
+  CONFIG_ARCH_BUTTONS                - Must be defined for button support
+  CONFIG_EXAMPLE_BUTTONS_MIN         - Lowest button number (MIN=0)
+  CONFIG_EXAMPLE_BUTTONS_MAX         - Highest button number (MAX=7)
+
+  CONFIG_ARCH_IRQBUTTONS             - Must be defined for interrupting button support
+  CONFIG_EXAMPLE_IRQBUTTONS_MIN      - Lowest interrupting button number (MIN=0)
+  CONFIG_EXAMPLE_IRQBUTTONS_MAX      - Highest interrupting button number (MAX=7)
+
+  Name strings for buttons:
+  
+    CONFIG_EXAMPLE_BUTTONS_NAME0, CONFIG_EXAMPLE_BUTTONS_NAME1,
+    CONFIG_EXAMPLE_BUTTONS_NAME2, CONFIG_EXAMPLE_BUTTONS_NAME3,
+    CONFIG_EXAMPLE_BUTTONS_NAME4, CONFIG_EXAMPLE_BUTTONS_NAME5,
+    CONFIG_EXAMPLE_BUTTONS_NAME6, CONFIG_EXAMPLE_BUTTONS_NAME7,
+
+  Additional architecture-/board- specific configuration settings may also
+  be required.
+
+  NOTE: This test exercises internal button driver interfaces.  As such, it
+  relies on internal OS interfaces that are not normally available to a
+  user-space program.  As a result, this example cannot be used if a
+  NuttX is built as a protected, supervisor kernel (CONFIG_NUTTX_KERNEL).
+
+examples/can
+^^^^^^^^^^^^
+
+  If the CAN device is configured in loopback mode, then this example can
+  be used to test the CAN device in loop back mode.  It simple sinces a
+  sequence of CAN messages and verifies that those messages are returned
+  exactly as sent.
+
+  This test depends on these specific CAN/NSH configurations settings (your
+  specific CAN settings might require additional settings).
+
+    CONFIG_CAN - Enables CAN support.
+    CONFIG_CAN_LOOPBACK - A CAN driver may or may not support a loopback
+      mode for testing. The STM32 CAN driver does support loopback mode.
+    CONFIG_NSH_BUILTIN_APPS - Build the CAN test as an NSH built-in function.
+      Default: Built as a standalone problem
+ 
+  Specific configuration options for this example include:
+ 
+    CONFIG_EXAMPLES_CAN_DEVPATH - The path to the CAN device. Default: /dev/can0
+    CONFIG_EXAMPLES_CAN_NMSGS - If CONFIG_NSH_BUILTIN_APPS
+      is defined, then the number of loops is provided on the command line
+      and this value is ignored.  Otherwise, this number of CAN message is
+      collected and the program terminates.  Default:  If built as an NSH
+      built-in, the default is 32.  Otherwise messages are sent and received
+      indefinitely.
+
+  The default behavior assumes loopback mode.  Messages are sent, then read
+  and verified.  The behavior can be altered for other kinds of testing where
+  the test only sends or received (but does not verify) can messages.
+
+   CONFIG_EXAMPLES_CAN_READONLY - Only receive messages
+   CONFIG_EXAMPLES_CAN_WRITEONLY - Only send messages
+
+examples/cdcacm
+^^^^^^^^^^^^^^^
+
+  This very simple example shows how a USB CDC/ACM serial can be dynamically
+  connected and disconnected from a host.  This example can only be used as
+  an NSH built-int command.  If built-in, then two new NSH commands will be
+  supported:
+
+    1. sercon - Connect the CDC/ACM serial device
+    2. serdis - Disconnect the CDC/ACM serial device
+
+  Configuration prequisites (not complete):
+
+    CONFIG_USBDEV=y                 : USB device support must be enabled
+    CONFIG_CDCACM=y                 : The CDC/ACM driver must be built
+    CONFIG_NSH_BUILTIN_APPS         : NSH built-in application support must be enabled
+
+  Configuration options specific to this example:
+
+    CONFIG_EXAMPLES_CDCACM_DEVMINOR : The minor number of the CDC/ACM device.
+                                    : i.e., the 'x' in /dev/ttyACMx
+
+  If CONFIG_USBDEV_TRACE is enabled (or CONFIG_DEBUG and CONFIG_DEBUG_USB, or
+  CONFIG_USBDEV_TRACE), then the example code will also initialize the USB trace
+  output.  The amount of trace output can be controlled using:
+
+  CONFIG_EXAMPLES_CDCACM_TRACEINIT
+    Show initialization events
+  CONFIG_EXAMPLES_CDCACM_TRACECLASS
+    Show class driver events
+  CONFIG_EXAMPLES_CDCACM_TRACETRANSFERS
+    Show data transfer events
+  CONFIG_EXAMPLES_CDCACM_TRACECONTROLLER
+    Show controller events
+  CONFIG_EXAMPLES_CDCACM_TRACEINTERRUPTS
+    Show interrupt-related events.
+
+  Note:  This example is only enables or disable USB CDC/ACM via the NSH
+  'sercon' and 'serdis' command.  It will enable and disable tracing per
+  the settings before enabling and after disabling the CDC/ACM device. It
+  will not, however, monitor buffered trace data in the interim.  If
+  CONFIG_USBDEV_TRACE is defined (and the debug options are not), other
+  application logic will need to monitor the buffered trace data.
+
+examples/composite
+^^^^^^^^^^^^^^^^^^
+
+  This example test a USB composite device.  The only supported composite is
+  CDC/ACM serial with a USB mass storage device.
+
+  Required overall configuration:
+
+  CONFIG_USBDEV=y           - USB device support
+  CONFIG_USBDEV_COMPOSITE=y - USB composite device support
+  CONFIG_COMPOSITE_IAD=y    - Interface associate descriptor needed
+
+  CONFIG_CDCACM=y           - USB CDC/ACM serial device support
+  CONFIG_CDCACM_COMPOSITE=y - USB CDC/ACM serial composite device support
+  CONFIG_CDCACM_IFNOBASE=0  - CDC/ACM interfaces start with number 0
+  CONFIG_CDCACM_STRBASE=4   - Base of string numbers (not really needed)
+  CONFIG_CDCACM_EPINTIN=1   - Endpoint numbers must be unique
+  CONFIG_CDCACM_EPBULKIN=2
+  CONFIG_CDCACM_EPBULKOUT=3
+
+  CONFIG_USBMSC             - USB mass storage device support
+  CONFIG_USBMSC_COMPOSITE=y - USB mass storage composite device support
+  CONFIG_USBMSC_IFNOBASE=2  - USB mass storage interfaces start with number 2
+  CONFIG_USBMSC_STRBASE=4   - Base of string numbers (needed)
+  CONFIG_USBMSC_EPBULKOUT=4 - Endpoint numbers must be unique
+  CONFIG_USBMSC_EPBULKIN=5
+
+  CONFIG_NSH_BUILTIN_APPS
+    This example can be built as two NSH "built-in" commands if this option
+    is selected: 'conn' will connect the USB composite device; 'msdis'
+    will disconnect the USB composite device.
+
+  Configuration options unique to this example:
+
+  CONFIG_EXAMPLES_COMPOSITE_DEBUGMM
+    Enables some debug tests to check for memory usage and memory leaks.
+
+  CONFIG_EXAMPLES_COMPOSITE_NLUNS
+    Defines the number of logical units (LUNs) exported by the USB storage
+    driver.  Each LUN corresponds to one exported block driver (or partition
+    of a block driver).  May be 1, 2, or 3.  Default is 1.
+  CONFIG_EXAMPLES_COMPOSITE_DEVMINOR1
+    The minor device number of the block driver for the first LUN. For
+    example, N in /dev/mmcsdN.  Used for registering the block driver. Default
+    is zero.
+  CONFIG_EXAMPLES_COMPOSITE_DEVPATH1
+    The full path to the registered block driver.  Default is "/dev/mmcsd0"
+  CONFIG_EXAMPLES_COMPOSITE_DEVMINOR2 and CONFIG_EXAMPLES_COMPOSITE_DEVPATH2
+    Similar parameters that would have to be provided if CONFIG_EXAMPLES_COMPOSITE_NLUNS
+    is 2 or 3.  No defaults.
+  CONFIG_EXAMPLES_COMPOSITE_DEVMINOR3 and CONFIG_EXAMPLES_COMPOSITE_DEVPATH2
+    Similar parameters that would have to be provided if CONFIG_EXAMPLES_COMPOSITE_NLUNS
+    is 3.  No defaults.
+  CONFIG_EXAMPLES_COMPOSITE_BUFLEN. Default 256.
+
+  CONFIG_EXAMPLES_COMPOSITE_TTYUSB - The minor number of the USB serial device.
+    Default is zero (corresponding to /dev/ttyUSB0 or /dev/ttyACM0).  Default is zero.
+  CCONFIG_EXAMPLES_COMPOSITE_SERDEV - The string corresponding to
+    CONFIG_EXAMPLES_COMPOSITE_TTYUSB.  The default is "/dev/ttyUSB0" (for the PL2303
+    emulation) or "/dev/ttyACM0" (for the CDC/ACM serial device).
+  CONFIG_EXAMPLES_COMPOSITE_BUFSIZE - The size of the serial I/O buffer in
+    bytes.  Default 256 bytes.
+ 
+  If CONFIG_USBDEV_TRACE is enabled (or CONFIG_DEBUG and CONFIG_DEBUG_USB), then
+  the example code will also manage the USB trace output.  The amount of trace output
+  can be controlled using:
+
+  CONFIG_EXAMPLES_COMPOSITE_TRACEINIT
+    Show initialization events
+  CONFIG_EXAMPLES_COMPOSITE_TRACECLASS
+    Show class driver events
+  CONFIG_EXAMPLES_COMPOSITE_TRACETRANSFERS
+    Show data transfer events
+  CONFIG_EXAMPLES_COMPOSITE_TRACECONTROLLER
+    Show controller events
+  CONFIG_EXAMPLES_COMPOSITE_TRACEINTERRUPTS
+    Show interrupt-related events.
+
+examples/dhcpd
+^^^^^^^^^^^^^^
+
+  This examples builds a tiny DCHP server for the target system.
+  
+  NOTE: For test purposes, this example can be built as a
+  host-based DHCPD server.  This can be built as follows:
+
+    cd examples/dhcpd
+    make -f Makefile.host TOPDIR=<nuttx-directory>
+
+  NuttX configuration settings:
+  
+    CONFIG_NET=y                   - Of course
+    CONFIG_NSOCKET_DESCRIPTORS     - And, of course, you must allocate some
+                                     socket descriptors.
+    CONFIG_NET_UDP=y               - UDP support is required for DHCP
+                                     (as well as various other UDP-related
+                                     configuration settings)
+    CONFIG_NET_BROADCAST=y         - UDP broadcast support is needed.
+
+    CONFIG_EXAMPLE_DHCPD_NOMAC     - (May be defined to use software assigned MAC)
+    CONFIG_EXAMPLE_DHCPD_IPADDR    - Target IP address
+    CONFIG_EXAMPLE_DHCPD_DRIPADDR  - Default router IP addess
+    CONFIG_EXAMPLE_DHCPD_NETMASK   - Network mask
+
+  See also CONFIG_NETUTILS_DHCPD_* settings described elsewhere
+  and used in netutils/dhcpd/dhcpd.c. These settings are required
+  to described the behavior of the daemon.
+
+  Applications using this example will need to provide an appconfig
+  file in the configuration driver with instruction to build applications
+  like:
+
+  CONFIGURED_APPS += uiplib
+
+examples/discover
+^^^^^^^^^^^^^^^^^
+
+  This example exercises netutils/discover utility.  This example initializes
+  and starts the UDP discover daemon. This daemon is useful for discovering
+  devices in local networks, especially with DHCP configured devices.  It
+  listens for UDP broadcasts which also can include a device class so that
+  groups of devices can be discovered. It is also possible to address all
+  classes with a kind of broadcast discover.
+
+  This example will automatically be built as an NSH built-in if
+  CONFIG_NSH_BUILTIN_APPS is selected.  Otherwise, it will be a standalone
+  program with entry point "discover_main".
+
+  NuttX configuration settings:
+
+    CONFIG_EXAMPLE_DISCOVER_DHCPC - DHCP Client
+    CONFIG_EXAMPLE_DISCOVER_NOMAC - Use canned MAC address
+    CONFIG_EXAMPLE_DISCOVER_IPADDR - Target IP address
+    CONFIG_EXAMPLE_DISCOVER_DRIPADDR - Router IP address
+    CONFIG_EXAMPLE_DISCOVER_NETMASK - Network Mask
+
+examples/ftpc
+^^^^^^^^^^^^^
+
+  This is a simple FTP client shell used to exercise the capabilities
+  of the FTPC library (apps/netutils/ftpc).  This example is configured
+  to that it will only work as a "built-in" program that can be run from
+  NSH when CONFIG_NSH_BUILTIN_APPS is defined.
+
+  From NSH, the startup command sequence is as follows.  This is only
+  an example, your configration could have different mass storage devices,
+  mount paths, and FTP directories:
+
+    nsh> mount -t vfat /dev/mmcsd0 /tmp # Mount the SD card at /tmp
+    nsh> cd /tmp                        # cd into the /tmp directory
+    nsh> ftpc xx.xx.xx.xx[:pp]          # Start the FTP client
+    nfc> login <name> <password>        # Log into the FTP server
+    nfc> help                           # See a list of FTP commands
+
+  where xx.xx.xx.xx is the IP address of the FTP server and pp is an
+  optional port number.
+
+  NOTE:  By default, FTPC uses readline to get data from stdin.  So your
+  appconfig file must have the following build path:
+
+    CONFIGURED_APPS += system/readline
+
+  NOTE: If you use the ftpc task over a telnet NSH connection, then you
+  should set the following configuration item:
+
+    CONFIG_EXAMPLES_FTPC_FGETS=y
+
+  By default, the FTPC client will use readline() to get characters from
+  the console.  Readline includes and command-line editor and echos
+  characters received in stdin back through stdout.  Neither of these
+  behaviors are desire-able if Telnet is used.
+
+  You may also want to define the following in your configuration file.
+  Otherwise, you will have not feeback about what is going on:
+ 
+    CONFIG_DEBUG=y
+    CONFIG_DEBUG_VERBOSE=y
+    CONFIG_DEBUG_FTPC=y
+
+examples/ftpd
+^^^^^^^^^^^^^^
+
+  This example exercises the FTPD daemon at apps/netuils/ftpd.  Below are
+  configurations specific to the FTPD example (the FTPD daemon itself may
+  require other configuration options as well).
+
+   CONFIG_EXAMPLES_FTPD_PRIO - Priority of the FTP daemon.
+     Default: SCHED_PRIORITY_DEFAULT
+   CONFIG_EXAMPLES_FTPD_STACKSIZE - Stack size allocated for the
+     FTP daemon. Default: 2048
+   CONFIG_EXAMPLES_FTPD_NONETINIT - Define to suppress configuration of the
+     network by apps/examples/ftpd.  You would need to suppress network
+     configuration if the network is configuration prior to running the
+     example.
+
+  NSH always initializes the network so if CONFIG_NSH_BUILTIN_APPS is
+  defined, so is CONFIG_EXAMPLES_FTPD_NONETINIT (se it does not explicitly
+  need to be defined in that case):
+
+    CONFIG_NSH_BUILTIN_APPS - Build the FTPD daemon example test as an
+      NSH built-in function.  By default the FTPD daemon will be built
+      as a standalone application.
+
+  If CONFIG_EXAMPLES_FTPD_NONETINIT is not defined, then the following may
+  be specified to customized the network configuration:
+
+    CONFIG_EXAMPLE_FTPD_NOMAC - If the hardware has no MAC address of its
+      own, define this =y to provide a bogus address for testing.
+    CONFIG_EXAMPLE_FTPD_IPADDR - The target IP address.  Default 10.0.0.2
+    CONFIG_EXAMPLE_FTPD_DRIPADDR - The default router address. Default
+      10.0.0.1
+    CONFIG_EXAMPLE_FTPD_NETMASK - The network mask.  Default: 255.255.255.0
+
+  Other required configuration settings:  Of course TCP networking support
+  is required.  But here are a couple that are less obvious:
+
+    CONFIG_DISABLE_PTHREAD - pthread support is required
+    CONFIG_DISABLE_POLL - poll() support is required
+
+  Other FTPD configuration options thay may be of interest:
+
+    CONFIG_FTPD_VENDORID - The vendor name to use in FTP communications.
+      Default: "NuttX"
+    CONFIG_FTPD_SERVERID - The server name to use in FTP communications.
+      Default: "NuttX FTP Server"
+    CONFIG_FTPD_CMDBUFFERSIZE - The maximum size of one command.  Default:
+      512 bytes.
+    CONFIG_FTPD_DATABUFFERSIZE - The size of the I/O buffer for data
+      transfers.  Default: 2048 bytes.
+    CONFIG_FTPD_WORKERSTACKSIZE - The stacksize to allocate for each
+      FTP daemon worker thread.  Default:  2048 bytes.
+
+  The appconfig file (apps/.config) should include:
+
+    CONFIGURED_APPS += examples/ftpd
+    CONFIGURED_APPS += netutils/uiplib
+    CONFIGURED_APPS += netutils/ftpd
+
+examples/hello
+^^^^^^^^^^^^^^
+
+  This is the mandatory, "Hello, World!!" example.  It is little more
+  than examples/null with a single printf statement.  Really useful only
+  for bringing up new NuttX architectures.
+
+  * CONFIG_EXAMPLES_HELLO_BUILTIN
+    Build the "Hello, World" example as an NSH built-in application.
+
+examples/helloxx
+^^^^^^^^^^^^^^^^
+
+  This is C++ version of the "Hello, World!!" example.  It is intended
+  only to verify that the C++ compiler is functional, that basic C++
+  library suupport is available, and that class are instantiated
+  correctly.
+
+  NuttX configuration prerequisites:
+
+    CONFIG_HAVE_CXX -- Enable C++ Support
+
+  Optional NuttX configuration settings:
+  
+    CONFIG_HAVE_CXXINITIALIZE -- Enable support for static constructors
+      (may not be available on all platforms).
+
+  NuttX configuration settings specific to this examp;le:
+
+    CONFIG_EXAMPLES_HELLOXX_BUILTIN -- Build the helloxx example as a
+      "built-in"  that can be executed from the NSH command line.
+    CONFIG_EXAMPLES_HELLOXX_NOSTACKCONST - Set if the system does not
+      support construction of objects on the stack.
+
+  Also needed:
+
+    CONFIG_HAVE_CXX=y
+
+  And you may have to tinker with the following to get libxx to compile
+  properly:
+
+    CONFIG_CXX_NEWLONG=y or =n
+
+  The argument of the 'new' operators should take a type of size_t.  But size_t
+  has an unknown underlying.  In the nuttx sys/types.h header file, size_t
+  is typed as uint32_t (which is determined by architecture-specific logic).
+  But the C++ compiler may believe that size_t is of a different type resulting
+  in compilation errors in the operator.  Using the underlying integer type
+  Instead of size_t seems to resolve the compilation issues.
+
+examples/hidkbd
+^^^^^^^^^^^^^^^^
+
+  This is a simple test to debug/verify the USB host HID keyboard class
+  driver.
+
+    CONFIG_EXAMPLES_HIDKBD_DEFPRIO - Priority of "waiter" thread.
+    CONFIG_EXAMPLES_HIDKBD_STACKSIZE - Stacksize of "waiter" thread.
+
+examples/igmp
+^^^^^^^^^^^^^
+
+  This is a trivial test of the NuttX IGMP capability.  It present it
+  does not do much of value -- Much more is needed in order to verify
+  the IGMP features!
+
+  * CONFIG_EXAMPLE_IGMP_NOMAC
+      Set if the hardware has no MAC address; one will be assigned
+  * CONFIG_EXAMPLE_IGMP_IPADDR
+      Target board IP address
+  * CONFIG_EXAMPLE_IGMP_DRIPADDR
+      Default router address
+  * CONFIG_EXAMPLE_IGMP_NETMASK
+      Network mask
+  * CONFIG_EXAMPLE_IGMP_GRPADDR
+      Multicast group address
+
+  Applications using this example will need to provide an appconfig
+  file in the configuration driver with instruction to build applications
+  like:
+
+  CONFIGURED_APPS += uiplib
+
+examples/lcdrw
+^^^^^^^^^^^^^^
+
+  This example may be used to verify if you can or cannot read data
+  correctly from an LCD interface.  At present, this supports only LCDs
+  with RGB565 color format.
+
+  * CONFIG_EXAMPLES_LDCRW_DEVNO
+      LCD device number.  Default: 0
+  * CONFIG_EXAMPLES_LDCRW_XRES
+      LCD X resolution.  Default: 240
+  * CONFIG_EXAMPLES_LDCRW_YRES
+      LCD Y resolution.  Default: 320
+  
+examples/mm
+^^^^^^^^^^^
+
+  This is a simplified version of the "built-in" memory manager test of
+  mm/mm_test.c.  It is simplified because it does not have access to the
+  internals of the memory manager as does mm/mm_test.c, but it has the
+  advantage that it runs in the actual NuttX tasking environment (the
+  mm/mm_test.c only runs in a PC simulation environment).
+
+examples/modbus
+^^^^^^^^^^^^^^^
+
+  This is a port of the FreeModbus Linux demo.  It derives from the
+  demos/LINUX directory of the FreeModBus version 1.5.0 (June 6, 2010)
+  that can be downloaded in its entirety from http://developer.berlios.de/project/showfiles.php?group_id=6120.
+
+    CONFIG_EXAMPLES_MODBUS_PORT, Default 0 (for /dev/ttyS0)
+    CONFIG_EXAMPLES_MODBUS_BAUD, Default B38400
+    CONFIG_EXAMPLES_MODBUS_PARITY, Default MB_PAR_EVEN
+
+    CONFIG_EXAMPLES_MODBUS_REG_INPUT_START, Default 1000
+    CONFIG_EXAMPLES_MODBUS_REG_INPUT_NREGS, Default 4
+    CONFIG_EXAMPLES_MODBUS_REG_HOLDING_START, Default 2000
+    CONFIG_EXAMPLES_MODBUS_REG_HOLDING_NREGS, Default 130
+
+  The FreeModBus library resides at apps/modbus.  See apps/modbus/README.txt
+  for additional configuration information.
+
+examples/mount
+^^^^^^^^^^^^^^
+
+  This contains a simple test of filesystem mountpoints.
+
+  * CONFIG_EXAMPLES_MOUNT_DEVNAME
+      The name of the user-provided block device to mount.
+      If CONFIG_EXAMPLES_MOUNT_DEVNAME is not provided, then
+      a RAM disk will be configured.
+
+  * CONFIG_EXAMPLES_MOUNT_NSECTORS
+      The number of "sectors" in the RAM disk used when
+      CONFIG_EXAMPLES_MOUNT_DEVNAME is not defined.
+
+  * CONFIG_EXAMPLES_MOUNT_SECTORSIZE
+      The size of each sectors in the RAM disk used when
+      CONFIG_EXAMPLES_MOUNT_DEVNAME is not defined.
+
+  * CONFIG_EXAMPLES_MOUNT_RAMDEVNO
+      The RAM device minor number used to mount the RAM disk used
+      when CONFIG_EXAMPLES_MOUNT_DEVNAME is not defined.  The
+      default is zero (meaning that "/dev/ram0" will be used).
+
+examples/netttest
+^^^^^^^^^^^^^^^^^
+
+  This is a simple network test for verifying client- and server-
+  functionality in a TCP/IP connection.
+
+  Applications using this example will need to provide an appconfig
+  file in the configuration driver with instruction to build applications
+  like:
+
+  CONFIGURED_APPS += uiplib
+
+examples/nsh
+^^^^^^^^^^^^
+
+  This directory provides an example of how to configure and use
+  the NuttShell (NSH) application.  NSH is a simple shell
+  application.  NSH is described in its own README located at
+  apps/nshlib/README.txt
+
+  Applications using this example will need to provide an appconfig
+  file in the configuration driver with instruction to build applications
+  like:
+
+  CONFIGURED_APPS += nshlib
+
+  NOTE:  If the NSH serial console is used, then following is also
+  required to build the readline() library:
+
+  CONFIGURED_APPS += system/readline
+
+  And if networking is included:
+
+  CONFIGURED_APPS += uiplib
+  CONFIGURED_APPS += dhcpc
+  CONFIGURED_APPS += resolv
+  CONFIGURED_APPS += tftp
+  CONFIGURED_APPS += webclient
+
+  If the Telnet console is enabled, then the appconfig file (apps/.config)
+  should also include:
+
+  CONFIGURED_APPS += netutils/telnetd
+
+  Also if the Telnet console is enabled, make sure that you have the
+  following set in the NuttX configuration file or else the performance
+  will be very bad (because there will be only one character per TCP
+  transfer):
+  
+  CONFIG_STDIO_BUFFER_SIZE - Some value >= 64
+  CONFIG_STDIO_LINEBUFFER=y
+
+examples/nx
+^^^^^^^^^^^
+
+  This directory contains a simple test of a subset of the NX APIs
+  defined in include/nuttx/nx/nx.h.  The following configuration options
+  can be selected:
+
+    CONFIG_EXAMPLES_NX_BUILTIN -- Build the NX example as a "built-in"
+      that can be executed from the NSH command line    
+    CONFIG_EXAMPLES_NX_VPLANE -- The plane to select from the frame-
+      buffer driver for use in the test.  Default: 0
+    CONFIG_EXAMPLES_NX_DEVNO - The LCD device to select from the LCD
+      driver for use in the test: Default: 0
+    CONFIG_EXAMPLES_NX_BGCOLOR -- The color of the background.  Default depends on
+      CONFIG_EXAMPLES_NX_BPP.
+    CONFIG_EXAMPLES_NX_COLOR1 -- The color of window 1. Default depends on
+      CONFIG_EXAMPLES_NX_BPP.
+    CONFIG_EXAMPLES_NX_COLOR2 -- The color of window 2. Default depends on
+      CONFIG_EXAMPLES_NX_BPP.
+    CONFIG_EXAMPLES_NX_TBCOLOR -- The color of the toolbar. Default depends on
+      CONFIG_EXAMPLES_NX_BPP.
+    CONFIG_EXAMPLES_NX_FONTID - Selects the font (see font ID numbers in
+      include/nuttx/nx/nxfonts.h)
+    CONFIG_EXAMPLES_NX_FONTCOLOR -- The color of the fonts. Default depends on
+      CONFIG_EXAMPLES_NX_BPP.
+    CONFIG_EXAMPLES_NX_BPP -- Pixels per pixel to use.  Valid options
+      include 2, 4, 8, 16, 24, and 32.  Default is 32.
+    CONFIG_EXAMPLES_NX_RAWWINDOWS -- Use raw windows;  Default is to
+      use pretty, framed NXTK windows with toolbars.
+    CONFIG_EXAMPLES_NX_EXTERNINIT - The driver for the graphics device on
+      this platform requires some unusual initialization.  This is the
+      for, for example, SPI LCD/OLED devices.  If this configuration is
+      selected, then the platform code must provide an LCD initialization
+      function with a prototype like:
+
+      #ifdef CONFIG_NX_LCDDRIVER
+      FAR struct lcd_dev_s *up_nxdrvinit(unsigned int devno);
+      #else
+      FAR struct fb_vtable_s *up_nxdrvinit(unsigned int devno);
+      #endif
+
+  This test can be performed with either the single-user version of
+  NX or with the multiple user version of NX selected with CONFIG_NX_MULTIUSER.
+  If CONFIG_NX_MULTIUSER is defined, then the following configuration
+  options also apply:
+
+    CONFIG_EXAMPLES_NX_STACKSIZE -- The stacksize to use when creating
+      the NX server.  Default 2048
+    CONFIG_EXAMPLES_NX_CLIENTPRIO -- The client priority.  Default: 100
+    CONFIG_EXAMPLES_NX_SERVERPRIO -- The server priority.  Default: 120
+    CONFIG_EXAMPLES_NX_LISTENERPRIO -- The priority of the event listener
+      thread. Default 80.
+    CONFIG_EXAMPLES_NX_NOTIFYSIGNO -- The signal number to use with
+      nx_eventnotify().  Default: 4
+
+  If CONFIG_NX_MULTIUSER is defined, then the example also expects the
+  following settings and will generate an error if they are not as expected:
+
+    CONFIG_DISABLE_MQUEUE=n
+    CONFIG_DISABLE_SIGNALS=n
+    CONFIG_DISABLE_PTHREAD=n
+    CONFIG_NX_BLOCKING=y
+
+examples/nxconsole
+^^^^^^^^^^^^^^^^^^
+
+  This directory contains yet another version of the NuttShell (NSH).  This
+  version uses the NX console device defined in include/nuttx/nx/nxconsole.h
+  for output.  the result is that the NSH input still come from the standard
+  console input (probably a serial console).  But the text output will go to
+  an NX winbdow.  Prerequisite configuration settings for this test include:
+
+    CONFIG_NX=y              -- NX graphics must be enabled
+    CONFIG_NXCONSOLE=y       -- The NX console driver must be built
+    CONFIG_NX_MULTIUSER=y    -- NX multi-user support must be enabled.
+    CONFIG_DISABLE_MQUEUE=n  -- Message queue support must be available.
+    CONFIG_DISABLE_SIGNALS=n -- Signals are needed
+    CONFIG_DISABLE_PTHREAD=n -- pthreads are needed
+    CONFIG_NX_BLOCKING=y     -- pthread APIs must be blocking
+    CONFIG_NSH_CONSOLE=y     -- NSH must be configured to use a console.
+
+  The following configuration options can be selected to customize the
+  test:
+
+    CONFIG_EXAMPLES_NXCON_VPLANE -- The plane to select from the frame-
+      buffer driver for use in the test.  Default: 0
+    CONFIG_EXAMPLES_NXCON_DEVNO - The LCD device to select from the LCD
+      driver for use in the test: Default: 0
+    CONFIG_EXAMPLES_NXCON_BGCOLOR -- The color of the background.  Default
+      Default is a darker royal blue.
+    CONFIG_EXAMPLES_NXCON_WCOLOR -- The color of the window. Default is a light
+      slate blue.
+    CONFIG_EXAMPLES_NXCON_FONTID -- Selects the font (see font ID numbers in
+      include/nuttx/nx/nxfonts.h)
+    CONFIG_EXAMPLES_NXCON_FONTCOLOR -- The color of the fonts. Default is
+      black.
+    CONFIG_EXAMPLES_NXCON_BPP -- Pixels per pixel to use.  Valid options
+      include 2, 4, 8, 16, 24, and 32.  Default is 32.
+    CONFIG_EXAMPLES_NXCON_TOOLBAR_HEIGHT -- The height of the toolbar.
+      Default: 16
+    CONFIG_EXAMPLES_NXCON_TBCOLOR -- The color of the toolbar. Default is
+      a medium grey.
+    CONFIG_EXAMPLES_NXCON_EXTERNINIT - The driver for the graphics device on
+      this platform requires some unusual initialization.  This is the
+      for, for example, SPI LCD/OLED devices.  If this configuration is
+      selected, then the platform code must provide an LCD initialization
+      function with a prototype like:
+
+      #ifdef CONFIG_NX_LCDDRIVER
+      FAR struct lcd_dev_s *up_nxdrvinit(unsigned int devno);
+      #else
+      FAR struct fb_vtable_s *up_nxdrvinit(unsigned int devno);
+      #endif
+
+    CONFIG_EXAMPLES_NXCON_MINOR -- The NX console device minor number.
+      Default is 0 corresponding to /dev/nxcon0
+    CONFIG_EXAMPLES_NXCON_DEVNAME -- The quoated, full path to the
+      NX console device corresponding to CONFIG_EXAMPLES_NXCON_MINOR.

+      Default: SCHED_PRIORITY_DEFAULT
+    CONFIG_EXAMPLES_NXCONSOLE_STACKSIZE - Stack size allocated for the
+      NxConsole task. Default: 2048
+
+  The following configuration settings determine how to set up the NX
+  server (CONFIG_NX_MULTIUSER):
+
+    CONFIG_EXAMPLES_NXCON_STACKSIZE -- The stacksize to use when creating
+      the NX server.  Default 2048
+    CONFIG_EXAMPLES_NXCON_CLIENTPRIO -- The client priority.  Default: 100

+
+examples/nxffs
+^^^^^^^^^^^^^^
+
+  This is a test of the NuttX NXFFS FLASH file system.  This is an NXFFS
+  stress test and beats on the file system very hard.  It should only
+  be used in a simulation environment!  Putting this NXFFS test on real
+  hardware will most likely destroy your FLASH.  You have been warned.
+
+examples/nxflat
+^^^^^^^^^^^^^^^
+
+  This example builds a small NXFLAT test case.  This includes several
+  test programs under examples/nxflat tests.  These tests are build using
+  the NXFLAT format and installed in a ROMFS file system.  At run time,
+  each program in the ROMFS file system is executed.  Requires CONFIG_NXFLAT.
+
+examplex/nxhello
+^^^^^^^^^^^^^^^^
+
+  A very simple graphics example that just says "Hello, World!" in the
+  center of the display.
+

+    CONFIG_EXAMPLES_NXHELLO_FONTCOLOR -- The color of the fonts used in the
+      background window. Default depends on CONFIG_EXAMPLES_NXHELLO_BPP.
+    CONFIG_EXAMPLES_NXHELLO_BPP -- Pixels per pixel to use.  Valid options
+      include 2, 4, 8, 16, 24, and 32.  Default is 32.
+    CONFIG_EXAMPLES_NXHELLO_EXTERNINIT - The driver for the graphics device on
+      this platform requires some unusual initialization.  This is the
+      for, for example, SPI LCD/OLED devices.  If this configuration is
+      selected, then the platform code must provide an LCD initialization
+      function with a prototype like:
+
+      #ifdef CONFIG_NX_LCDDRIVER
+      FAR struct lcd_dev_s *up_nxdrvinit(unsigned int devno);
+      #else
+      FAR struct fb_vtable_s *up_nxdrvinit(unsigned int devno);
+      #endif
+
+examples/nximage
+^^^^^^^^^^^^^^^^
+
+  This is a simple example that just puts the NuttX logo image in the center
+  of the display.  This only works for RGB23 (888), RGB16 (656), RGB8 (332),
+  and 8-bit greyscale for now.
+
+    CONFIG_EXAMPLES_NXIMAGE_BUILTIN -- Build the NXIMAGE example as a "built-in"
+      that can be executed from the NSH command line    
+    CONFIG_EXAMPLES_NXIMAGE_VPLANE -- The plane to select from the frame-
+      buffer driver for use in the test.  Default: 0
+    CONFIG_EXAMPLES_NXIMAGE_DEVNO - The LCD device to select from the LCD
+      driver for use in the test: Default: 0
+    CONFIG_EXAMPLES_NXIMAGE_BPP -- Pixels per pixel to use.  Valid options
+      include 8, 16, and 24.  Default is 16.
+    CONFIG_EXAMPLES_NXIMAGE_XSCALEp5, CONFIG_EXAMPLES_NXIMAGE_XSCALE1p5,
+    CONFIG_EXAMPLES_NXIMAGE_XSCALE2p0 -- The logo image width is 160 columns.
+      One of these may be defined to rescale the image horizontally by .5, 1.5,
+      or 2.0.
+    CONFIG_EXAMPLES_NXIMAGE_YSCALEp5, CONFIG_EXAMPLES_NXIMAGE_YSCALE1p5,
+    CONFIG_EXAMPLES_NXIMAGE_YSCALE2p0 -- The logo image height is 160 rows.

+      this platform requires some unusual initialization.  This is the
+      for, for example, SPI LCD/OLED devices.  If this configuration is
+      selected, then the platform code must provide an LCD initialization
+      function with a prototype like:
+
+      #ifdef CONFIG_NX_LCDDRIVER

+      #else
+      FAR struct fb_vtable_s *up_nxdrvinit(unsigned int devno);
+      #endif
+
+    How was that run-length encoded image produced?
+
+    a. I used GIMP output the image as a .c file.
+    b. I added som C logic to palette-ize the RGB image in the GIMP .c file
+    c. Then I add some simple run-length encoding to palette-ized image.
+
+    NOTE: As of this writing, most of the pixel depth, scaling options, and
+    combinations thereof  have not been tested.

+      #endif
+
+examples/nxtext
+^^^^^^^^^^^^^^^
+
+  This directory contains another simple test of a subset of the NX APIs
+  defined in include/nuttx/nx/nx.h.  This text focuses on text displays on
+  the dispaly background combined with pop-up displays over the text.
+  The text display will continue to update while the pop-up is visible.
+
+  NOTE:  This example will *only* work with FB drivers and with LCD
+  drivers that support reading the contents of the internal LCD memory
+  *unless* you define CONFIG_EXAMPLES_NXTEXT_NOGETRUN.  If you notice
+  garbage on the display or a failure at the point where the display
+  should scroll, it is probably because you have an LCD driver that is
+  write-only.
+  
+  The following configuration options can be selected:
+
+    CONFIG_EXAMPLES_NXTEXT_BUILTIN -- Build the NXTEXT example as a "built-in"
+      that can be executed from the NSH command line

+      background text (see font ID numbers in include/nuttx/nx/nxfonts.h)
+    CONFIG_EXAMPLES_NXTEXT_BGFONTCOLOR -- The color of the fonts used in the
+      background window. Default depends on CONFIG_EXAMPLES_NXTEXT_BPP.
+    CONFIG_EXAMPLES_NXTEXT_PUCOLOR -- The color of the pop-up window.  Default
+      depends on CONFIG_EXAMPLES_NXTEXT_BPP.
+    CONFIG_EXAMPLES_NXTEXT_PUFONTID - Selects the font to use in the pop-up
+      windows (see font ID numbers in include/nuttx/nx/nxfonts.h)
+    CONFIG_EXAMPLES_NXTEXT_PUFONTCOLOR -- The color of the fonts used in the
+      background window. Default depends on CONFIG_EXAMPLES_NXTEXT_BPP.
+    CONFIG_EXAMPLES_NXTEXT_BPP -- Pixels per pixel to use.  Valid options
+      include 2, 4, 8, 16, 24, and 32.  Default is 32.
+    CONFIG_EXAMPLES_NXTEXT_NOGETRUN -- If your display is read-only OR if
+      reading is not reliable, then select this configuration to avoid
+      reading from the display.
+    CONFIG_EXAMPLES_NXTEXT_EXTERNINIT - The driver for the graphics device on
+      this platform requires some unusual initialization.  This is the
+      for, for example, SPI LCD/OLED devices.  If this configuration is
+      selected, then the platform code must provide an LCD initialization
+      function with a prototype like:
+
+      #ifdef CONFIG_NX_LCDDRIVER
+      FAR struct lcd_dev_s *up_nxdrvinit(unsigned int devno);

+      #endif
+
+    CONFIG_EXAMPLES_NXTEXT_BMCACHE - The maximum number of characters that
+      can be put in the background window.  Default is 128.
+    CONFIG_EXAMPLES_NXTEXT_GLCACHE - The maximum nuber of pre-rendered
+      fonts that can be retained for the background window.
+
+  This test can be performed with either the single-user version of
+  NX or with the multiple user version of NX selected with CONFIG_NX_MULTIUSER.
+  If CONFIG_NX_MULTIUSER is defined, then the following configuration
+  options also apply:
+
+    CONFIG_EXAMPLES_NXTEXT_STACKSIZE -- The stacksize to use when creating

+  following settings and will generate an error if they are not as expected:
+
+    CONFIG_DISABLE_MQUEUE=n
+    CONFIG_DISABLE_SIGNALS=n
+    CONFIG_DISABLE_PTHREAD=n
+    CONFIG_NX_BLOCKING=y
+
+examples/null
+^^^^^^^^^^^^^
+
+  This is the do nothing application.  It is only used for bringing
+  up new NuttX architectures in the most minimal of environments.
+
+examples/ostest
+^^^^^^^^^^^^^^^
+
+  This is the NuttX 'qualification' suite.  It attempts to exercise
+  a broad set of OS functionality.  Its coverage is not very extensive
+  as of this writing, but it is used to qualify each NuttX release.
+
+  The behavior of the ostest can be modified with the following
+  settings in the configs/<board-name>/defconfig file:
+
+  * CONFIG_EXAMPLES_OSTEST_BUILTIN
+      Build the OS test example as an NSH built-in application.
+  * CONFIG_EXAMPLES_OSTEST_LOOPS
+      Used to control the number of executions of the test.  If
+      undefined, the test executes one time.  If defined to be
+      zero, the test runs forever.
+  * CONFIG_EXAMPLES_OSTEST_STACKSIZE
+      Used to create the ostest task.  Default is 8192.
+  * CONFIG_EXAMPLES_OSTEST_NBARRIER_THREADS
+      Specifies the number of threads to create in the barrier
+      test.  The default is 8 but a smaller number may be needed on
+      systems without sufficient memory to start so many threads.
+
+examples/pashello
+^^^^^^^^^^^^^^^^^
+
+  This is "Hello, World" implemented via the Pascal P-Code interpreter. In
+  order to use this example, you must first download and install the
+  NuttX pascal module.  After unpacking the pascal module, you can find
+  installation instructions in pascal/nuttx/README.txt.
+
+  The correct install location for the NuttX examples and build files is
+  apps/interpreters.
+
+examples/pipe
+^^^^^^^^^^^^^
+
+  A test of the mkfifo() and pipe() APIs.
+
+ * CONFIG_EXAMPLES_PIPE_STACKSIZE
+     Sets the size of the stack to use when creating the child tasks.
+     The default size is 1024.
+
+examples/poll
+^^^^^^^^^^^^^
+
+  A test of the poll() and select() APIs using FIFOs and, if available,
+  stdin, and a TCP/IP socket.  In order to build this test, you must the
+  following selected in your NuttX configuration file:
+
+  CONFIG_NFILE_DESCRIPTORS          - Defined to be greater than 0
+  CONFIG_DISABLE_POLL               - NOT defined
+
+  In order to use the TCP/IP select test, you have also the following
+  additional things selected in your NuttX configuration file:
+
+  CONFIG_NET                        - Defined for general network support
+  CONFIG_NET_TCP                    - Defined for TCP/IP support
+  CONFIG_NSOCKET_DESCRIPTORS        - Defined to be greater than 0
+  CONFIG_NET_NTCP_READAHEAD_BUFFERS - Defined to be greater than zero
+
+  CONFIG_EXAMPLE_POLL_NOMAC         - (May be defined to use software assigned MAC)
+  CONFIG_EXAMPLE_POLL_IPADDR        - Target IP address
+  CONFIG_EXAMPLE_POLL_DRIPADDR      - Default router IP addess
+  CONFIG_EXAMPLE_POLL_NETMASK       - Network mask
+
+  In order to for select to work with incoming connections, you
+  must also select:
+
+  CONFIG_NET_TCPBACKLOG             - Incoming connections pend in a backlog until accept() is called.
+
+  In additional to the target device-side example, there is also
+  a host-side application in this directory.  It can be compiled under
+  Linux or Cygwin as follows:
+
+    cd examples/usbserial
+    make -f Makefile.host TOPDIR=<nuttx-directory> TARGETIP=<target-ip>
+
+  Where <target-ip> is the IP address of your target board.
+
+  This will generate a small program called 'host'.  Usage:
+
+  1. Build the examples/poll target program with TCP/IP poll support
+     and start the target.
+
+  3. Then start the host application:
+
+       ./host
+
+  The host and target will exchange are variety of small messages. Each
+  message sent from the host should cause the select to return in target.
+  The target example should read the small message and send it back to
+  the host.  The host should then receive the echo'ed message.
+
+  If networking is enabled, applications using this example will need to
+  provide an appconfig file in the configuration driver with instruction
+  to build applications like:
+
+  CONFIGURED_APPS += uiplib
+
+examples/pwm
+^^^^^^^^^^^^
+
+  A test of a PWM device driver. It simply enables a pulsed output for
+  a specified frequency and duty for a specified period of time.  This
+  example can ONLY be built as an NSH built-in function.
+
+  This test depends on these specific PWM/NSH configurations settings (your
+  specific PWM settings might require additional settings).
+
+    CONFIG_PWM - Enables PWM support.
+    CONFIG_EXAMPLES_PWM_COUNT - Enabled PWM pulse count support (if the
+      hardware supports it).
+    CONFIG_NSH_BUILTIN_APPS - Build the PWM test as an NSH built-in function.
+      Default: Not built!  The example can only be used as an NSH built-in
+      application
+ 
+  Specific configuration options for this example include:
+ 
+    CONFIG_EXAMPLES_PWM_DEVPATH - The path to the default PWM device. Default: /dev/pwm0
+    CONFIG_EXAMPLES_PWM_FREQUENCY - The initial PWM frequency.  Default: 100 Hz
+    CONFIG_EXAMPLES_PWM_DUTYPCT - The initial PWM duty as a percentage.  Default: 50%
+    CONFIG_EXAMPLES_PWM_DURATION - The initial PWM pulse train duration in seconds.
+       Used only if the current pulse count is zero (pulse count is only supported
+       if CONFIG_PWM_PULSECOUNT is defined). Default: 5 seconds
+    CONFIG_EXAMPLES_PWM_PULSECOUNT - The initial PWM pulse count.  This option is
+       only available if CONFIG_PWM_PULSECOUNT is non-zero. Default: 0 (i.e., use
+       the duration, not the count).
+
+examples/qencoder
+^^^^^^^^^^^^^^^^^
+
+  This example is a simple test of a Quadrature Encoder driver.  It simply reads
+  positional data from the encoder and prints it.,
+
+  This test depends on these specific QE/NSH configurations settings (your
+  specific PWM settings might require additional settings).
+
+    CONFIG_QENCODER - Enables quadrature encoder support (upper-half driver).
+    CONFIG_NSH_BUILTIN_APPS - Build the QE test as an NSH built-in function.
+      Default: Built as a standalone progrem.
+
+  Additional configuration options will mostly likely be required for the board-
+  specific lower-half driver.  See the README.txt file in your board configuration
+  directory.
+
+  Specific configuration options for this example include:
+ 
+  CONFIG_EXAMPLES_QENCODER_DEVPATH - The path to the QE device. Default:
+    /dev/qe0
+  CONFIG_EXAMPLES_QENCODER_NSAMPLES - If CONFIG_NSH_BUILTIN_APPS
+    is defined, then the number of samples is provided on the command line
+    and this value is ignored.  Otherwise, this number of samples is
+    collected and the program terminates.  Default:  Samples are collected
+    indefinitely.
+  CONFIG_EXAMPLES_QENCODER_DELAY - This value provides the delay (in
+    milliseonds) between each sample.  If CONFIG_NSH_BUILTIN_APPS
+    is defined, then this value is the default delay if no other delay is
+    provided on the command line.  Default:  100 milliseconds
+
+examples/rgmp
+^^^^^^^^^^^^^
+
+  RGMP stands for RTOS and GPOS on Multi-Processor.  RGMP is a project for 
+  running GPOS and RTOS simultaneously on multi-processor platforms. You can
+  port your favorite RTOS to RGMP together with an unmodified Linux to form a
+  hybrid operating system. This makes your application able to use both RTOS
+  and GPOS features.
+
+  See http://rgmp.sourceforge.net/wiki/index.php/Main_Page for further
+
+  At present, the RGMP example folder contains only an empty rgmp_main.c file.
+
+examples/romfs
+^^^^^^^^^^^^^^
+
+  This example exercises the romfs filesystem.  Configuration options
+  include:
+
+  * CONFIG_EXAMPLES_ROMFS_RAMDEVNO
+      The minor device number to use for the ROM disk.  The default is
+      1 (meaning /dev/ram1)
+
+  * CONFIG_EXAMPLES_ROMFS_SECTORSIZE
+      The ROM disk sector size to use.  Default is 64.
+
+  * CONFIG_EXAMPLES_ROMFS_MOUNTPOINT
+      The location to mount the ROM disk.  Deafault: "/usr/local/share"
+
+examples/sendmail
+^^^^^^^^^^^^^^^^^
+
+  This examples exercises the uIP SMTP logic by sending a test message
+  to a selected recipient.  This test can also be built to execute on
+  the Cygwin/Linux host environment:
+
+    cd examples/sendmail
+    make -f Makefile.host TOPDIR=<nuttx-directory>
+
+ Settings unique to this example include:
+
+    CONFIG_EXAMPLE_SENDMAIL_NOMAC     - May be defined to use software assigned MAC (optional)
+    CONFIG_EXAMPLE_SENDMAIL_IPADDR    - Target IP address (required)
+    CONFIG_EXAMPLE_SENDMAIL_DRIPADDR  - Default router IP addess (required)
+    CONFIG_EXAMPLE_SENDMAILT_NETMASK  - Network mask (required)
+    CONFIG_EXAMPLE_SENDMAIL_RECIPIENT - The recipient of the email (required)
+    CONFIG_EXAMPLE_SENDMAIL_SENDER    - Optional. Default: "nuttx-testing@example.com"
+    CONFIG_EXAMPLE_SENDMAIL_SUBJECT   - Optional. Default: "Testing SMTP from NuttX"
+    CONFIG_EXAMPLE_SENDMAIL_BODY   -    Optional. Default: "Test message sent by NuttX"
+
+  NOTE: This test has not been verified on the NuttX target environment.
+  As of this writing, unit-tested in the Cygwin/Linux host environment.
+
+  NOTE 2: This sendmail example only works for the simplest of 
+  environments.  Virus protection software on your host may have
+  to be disabled to allow you to send messages.  Only very open,
+  unprotected recipients can be used.  Most will protect themselves
+  from this test email because it looks like SPAM.
+
+  Applications using this example will need to provide an appconfig
+  file in the configuration driver with instruction to build applications
+  like:
+
+  CONFIGURED_APPS += uiplib
+  CONFIGURED_APPS += smtp
+
+examples/serloop
+^^^^^^^^^^^^^^^^
+
+  This is a mindlessly simple loopback test on the console.  Useful
+  for testing new serial drivers.  Configuration options include:
+
+  * CONFIG_EXAMPLES_SERLOOP_BUFIO
+      Use C buffered I/O (getchar/putchar) vs. raw console I/O
+      (read/read).
+
+examples/telnetd
+^^^^^^^^^^^^^^^^
+
+  This directory contains a functional port of the tiny uIP shell.  In
+  the NuttX environment, the NuttShell (at apps/nshlib) supercedes this
+  tiny shell and also supports telnetd.

+    CONFIG_EXAMPLE_TELNETD_DRIPADDR - The default router address. Default
+      10.0.0.1
+    CONFIG_EXAMPLE_TELNETD_NETMASK - The network mask.  Default: 255.255.255.0
+ 
+  The appconfig file (apps/.config) should include:
+
+    CONFIGURED_APPS += examples/telnetd
+    CONFIGURED_APPS += netutils/uiplib
+    CONFIGURED_APPS += netutils/telnetd
+
+  Also, make sure that you have the following set in the NuttX configuration
+  file or else the performance will be very bad (because there will be only
+  one character per TCP transfer):
+  
+    CONFIG_STDIO_BUFFER_SIZE - Some value >= 64
+    CONFIG_STDIO_LINEBUFFER=y
+
+examples/thttpd
+^^^^^^^^^^^^^^^
+
+  An example that builds netutils/thttpd with some simple NXFLAT
+  CGI programs.  see configs/README.txt for most THTTPD settings.
+  In addition to those, this example accepts:
+
+    CONFIG_EXAMPLE_THTTPD_NOMAC    - (May be defined to use software assigned MAC)
+    CONFIG_EXAMPLE_THTTPD_DRIPADDR - Default router IP addess
+    CONFIG_EXAMPLE_THTTPD_NETMASK  - Network mask
+
+  Applications using this example will need to provide an appconfig
+  file in the configuration directory with instruction to build applications
+  like:
+
+    CONFIGURED_APPS += uiplib
+    CONFIGURED_APPS += thttpd
+
+examples/tiff
+^^^^^^^^^^^^^
+
+  This is a simple unit test for the TIFF creation library at apps/graphic/tiff.
+  It is configured to work in the Linux user-mode simulation and has not been
+  tested in any other environment.  Since the example also depends on some
+  other logic to mount a file system, currently it will only work as an NSH
+  built-on, i.e., if the following is defined:
+
+    CONFIG_NSH_BUILTIN_APPS=y
+    CONFIG_EXAMPLES_TIFF_BUILTIN=y
+
+  At a miniumum, to run in an embedded environment, you will probably have to
+  change the configured paths to the TIFF files defined in the example.
+
+    CONFIG_EXAMPLES_TIFF_OUTFILE - Name of the resulting TIFF file.  Default is
+       "/tmp/result.tif"
+    CONFIG_EXAMPLES_TIFF_TMPFILE1/2 - Names of two temporaries files that
+      will be used in the file creation.  Defaults are "/tmp/tmpfile1.dat" and
+      "/tmp/tmpfile2.dat"
+
+  The following must also be defined in your apps/ configuration file:
+
+    CONFIGURED_APPS += examples/tiff
+    CONFIGURED_APPS += graphics/tiff
+
+examples/touchscreen
+^^^^^^^^^^^^^^^^^^^^
+
+  This configuration implements a simple touchscreen test at
+  apps/examples/touchscreen.  This test will create an empty X11 window
+  and will print the touchscreen output as it is received from the 
+  simulated touchscreen driver.
+
+    CONFIG_EXAMPLES_TOUCHSCREEN_BUILTIN - Build the touchscreen test as 
+      an NSH built-in function.  Default: Built as a standalone problem
+    CONFIG_EXAMPLES_TOUCHSCREEN_MINOR - The minor device number.  Minor=N
+      correspnds to touchscreen device /dev/input0.  Note this value must
+      with CONFIG_EXAMPLES_TOUCHSCREEN_DEVPATH.  Default 0.
+    CONFIG_EXAMPLES_TOUCHSCREEN_DEVPATH - The path to the touchscreen
+     device.  This must be consistent with CONFIG_EXAMPLES_TOUCHSCREEN_MINOR.
+     Default: "/dev/input0"
+    CONFIG_EXAMPLES_TOUCHSCREEN_NSAMPLES - If CONFIG_EXAMPLES_TOUCHSCREEN_BUILTIN
+     is defined, then the number of samples is provided on the command line
+     and this value is ignored.  Otherwise, this number of samples is
+     collected and the program terminates.  Default:  Samples are collected
+     indefinitely.
+
+  The following additional configurations must be set in the NuttX
+  configuration file:
+  
+    CONFIG_INPUTP=y
+    (Plus any touchscreen-specific settings).
+
+  The following must also be defined in your apps configuration file:
+
+    CONFIGURED_APPS += examples/tiff
+    CONFIGURED_APPS += graphics/tiff
+
+  The board-specific logic must provide the following interfaces that will
+  be called by the example in order to initialize and uninitialize the
+  touchscreen hardware:
+
+    int arch_tcinitialize(int minor);
+    int arch_tcuninitialize(void);
+
+examples/udp
+^^^^^^^^^^^^
+
+  This is a simple network test for verifying client- and server-
+  functionality over UDP.
+
+  Applications using this example will need to provide an appconfig
+  file in the configuration driver with instruction to build applications
+  like:
+
+  CONFIGURED_APPS += uiplib
+
+examples/uip
+^^^^^^^^^^^^
+
+  This is a port of uIP tiny webserver example application.  Settings
+  specific to this example include:
+
+    CONFIG_EXAMPLE_UIP_NOMAC     - (May be defined to use software assigned MAC)
+    CONFIG_EXAMPLE_UIP_IPADDR    - Target IP address
+    CONFIG_EXAMPLE_UIP_DRIPADDR  - Default router IP addess
+    CONFIG_EXAMPLE_UIP_NETMASK   - Network mask
+    CONFIG_EXAMPLE_UIP_DHCPC     - Select to get IP address via DHCP
+
+  If you use DHCPC, then some special configuration network options are
+  required.  These include:
+
+    CONFIG_NET=y                 - Of course
+    CONFIG_NSOCKET_DESCRIPTORS   - And, of course, you must allocate some
+                                   socket descriptors.
+    CONFIG_NET_UDP=y             - UDP support is required for DHCP
+                                   (as well as various other UDP-related
+                                   configuration settings).
+    CONFIG_NET_BROADCAST=y       - UDP broadcast support is needed.
+    CONFIG_NET_BUFSIZE=650       - Per RFC2131 (p. 9), the DHCP client must be
+    (or larger)                    prepared to receive DHCP messages of up to
+                                   576 bytes (excluding Ethernet, IP, or UDP
+                                   headers and FCS).
+
+  Other configuration items apply also to the selected webserver net utility.
+  Additional relevant settings for the uIP webserver net utility are:
+
+    CONFIG_NETUTILS_HTTPDSTACKSIZE
+    CONFIG_NETUTILS_HTTPDFILESTATS
+    CONFIG_NETUTILS_HTTPDNETSTATS
+
+  Applications using this example will need to provide an appconfig
+  file in the configuration driver with instruction to build applications
+  like:
+
+    CONFIGURED_APPS += uiplib
+    CONFIGURED_APPS += dhcpc
+    CONFIGURED_APPS += resolv
+    CONFIGURED_APPS += webserver
+
+  NOTE:  This example does depend on the perl script at
+  nuttx/tools/mkfsdata.pl.  You must have perl installed on your
+  development system at /usr/bin/perl.
+
+examples/usbserial
+^^^^^^^^^^^^^^^^^^
+
+  TARGET CONFIGURATION:
+
+    This is another implementation of "Hello, World" but this one uses
+    a USB serial driver.  Configuration options can be used to simply
+    the test. These options include:
+
+    CONFIG_EXAMPLES_USBSERIAL_INONLY
+       Only verify IN (device-to-host) data transfers.  Default: both
+    CONFIG_EXAMPLES_USBSERIAL_OUTONLY
+       Only verify OUT (host-to-device) data transfers.  Default: both
+    CONFIG_EXAMPLES_USBSERIAL_ONLYSMALL
+       Send only small, single packet messages.  Default: Send large and small.
+    CONFIG_EXAMPLES_USBSERIAL_ONLYBIG
+       Send only large, multi-packet messages.  Default: Send large and small.
+
+    If CONFIG_USBDEV_TRACE is enabled (or CONFIG_DEBUG and CONFIG_DEBUG_USB), then
+    the example code will also manage the USB trace output.  The amount of trace output
+    can be controlled using:
+
+    CONFIG_EXAMPLES_USBSERIAL_TRACEINIT
+      Show initialization events
+    CONFIG_EXAMPLES_USBSERIAL_TRACECLASS
+      Show class driver events
+    CONFIG_EXAMPLES_USBSERIAL_TRACETRANSFERS
+      Show data transfer events
+    CONFIG_EXAMPLES_USBSERIAL_TRACECONTROLLER
+      Show controller events
+    CONFIG_EXAMPLES_USBSERIAL_TRACEINTERRUPTS
+      Show interrupt-related events.
+
+    Error results are always shown in the trace output
+
+  HOST-SIDE TEST PROGRAM
+
+    In additional to the target device-side example, there is also a
+    host-side application in this directory.  This host side application
+    must be executed on a Linux host in order to perform the USBSERIAL
+    test.  The host application can be compiled under Linux (or Cygwin?)
+    as follows:
+
+      cd examples/usbserial
+      make -f Makefile.host TOPDIR=<nuttx-directory>
+
+  RUNNING THE TEST
+
+    This will generate a small program called 'host'.  Usage:
+
+    1. Build the examples/usbserial target program and start the target.
+
+    2. Wait a bit, then do enter:
+
+       dmesg
+
+       At the end of the dmesg output, you should see the serial
+       device was successfully idenfied and assigned to a tty device,
+       probably /dev/ttyUSB0 or /dev/ttyACM0 (depending on the configured
+       USB serial driver).
+
+    3. Then start the host application:
+
+         ./host [<tty-dev>]
+
+       Where:
+
+         <tty-dev> is the USB TTY device to use.   The default is
+         "/dev/ttyUSB0" (for the PL2303 emulation) or "/dev/ttyACM0" (for
+         the CDC/ACM serial device).
+
+    The host and target will exchange are variety of very small and very large
+    serial messages.
+
+examples/usbstorage
+^^^^^^^^^^^^^^^^^^^
+
+  This example registers a block device driver, then exports the block
+  the device using the USB storage class driver.  In order to use this
+  example, your board-specific logic must provide the function:
+
+    void usbmsc_archinitialize(void);
+
+  This function will be called by the example/usbstorage in order to
+  do the actual registration of the block device drivers.  For examples
+  of the implementation of usbmsc_archinitialize() see
+  configs/mcu123-lpc124x/src/up_usbmsc.c or
+  configs/stm3210e-eval/src/usbmsc.c
+
+  Configuration options:
+
+  CONFIG_EXAMPLES_USBMSC_BUILTIN
+    This example can be built as two NSH "built-in" commands if this option
+    is selected: 'msconn' will connect the USB mass storage device; 'msdis'
+    will disconnect the USB storage device.
+  CONFIG_EXAMPLES_USBMSC_NLUNS
+    Defines the number of logical units (LUNs) exported by the USB storage
+    driver.  Each LUN corresponds to one exported block driver (or partition
+    of a block driver).  May be 1, 2, or 3.  Default is 1.
+  CONFIG_EXAMPLES_USBMSC_DEVMINOR1
+    The minor device number of the block driver for the first LUN. For
+    example, N in /dev/mmcsdN.  Used for registering the block driver. Default
+    is zero.
+  CONFIG_EXAMPLES_USBMSC_DEVPATH1
+    The full path to the registered block driver.  Default is "/dev/mmcsd0"
+  CONFIG_EXAMPLES_USBMSC_DEVMINOR2 and CONFIG_EXAMPLES_USBMSC_DEVPATH2
+    Similar parameters that would have to be provided if CONFIG_EXAMPLES_USBMSC_NLUNS
+    is 2 or 3.  No defaults.
+  CONFIG_EXAMPLES_USBMSC_DEVMINOR3 and CONFIG_EXAMPLES_USBMSC_DEVPATH3
+    Similar parameters that would have to be provided if CONFIG_EXAMPLES_USBMSC_NLUNS
+    is 3.  No defaults.
+  CONFIG_EXAMPLES_USBMSC_DEBUGMM
+    Enables some debug tests to check for memory usage and memory leaks.
+
+  If CONFIG_USBDEV_TRACE is enabled (or CONFIG_DEBUG and CONFIG_DEBUG_USB), then
+  the example code will also manage the USB trace output.  The amount of trace output
+  can be controlled using:
+
+  CONFIG_EXAMPLES_USBMSC_TRACEINIT
+    Show initialization events
+  CONFIG_EXAMPLES_USBMSC_TRACECLASS
+    Show class driver events
+  CONFIG_EXAMPLES_USBMSC_TRACETRANSFERS
+    Show data transfer events
+  CONFIG_EXAMPLES_USBMSC_TRACECONTROLLER
+    Show controller events
+  CONFIG_EXAMPLES_USBMSC_TRACEINTERRUPTS
+    Show interrupt-related events.
+
+  Error results are always shown in the trace output
+
+  NOTE 1: When built as an NSH add-on command (CONFIG_EXAMPLES_USBMSC_BUILTIN=y),
+  Caution should be used to assure that the SD drive (or other storage device) is
+  not in use when the USB storage device is configured.  Specifically, the SD
+  driver should be unmounted like:
+
+  nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard # Card is mounted in NSH
+  ...
+  nsh> umount /mnd/sdcard                    # Unmount before connecting USB!!!
+  nsh> msconn                                # Connect the USB storage device
+  ...
+  nsh> msdis                                 # Disconnect USB storate device
+  nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard # Restore the mount
+
+  Failure to do this could result in corruption of the SD card format.
+
+  NOTE 2: This test exercises internal USB device driver interfaces.  As such,
+  it relies on internal OS interfaces that are not normally available to a
+  user-space program.  As a result, this example cannot be used if a
+  NuttX is built as a protected, supervisor kernel (CONFIG_NUTTX_KERNEL).
+
+examples/usbterm
+^^^^^^^^^^^^^^^^
+
+  This example implements a little USB terminal.. more of a USB "chat"
+  edited lines are received from the remote host connected via USB
+  serial and echoed out the target serial console.  Edited lines from
+  the local target serial console are received and forwarded to the
+  remote host via USB serial.
+
+  Usage:
+    - Build the example and load into the target FLASH
+    - Connect on  terminal to the target RS-232 connect and configure
+      for 115200 8N1.  For example, suppose this Tera Term on a Windows
+      box.
+    - Power up the target board
+    - Connect the USB to a Linux box.  Use the Linux dmesg command to
+      assure that the connect was successful.  The USB CDC ACM device
+      should appear as /dev/ttyACM0
+    - On the Linux box, open minicom with tty=/dev/ttyACM0.
+      Configure minicom so that (1) local characters are echoed and (2)
+      so that no CR is required.
+    - Now what you type on the target Tera Term window should echo on
+      the Linux  minicom window and, conversely, what you type on the
+      minicom winow should be echo in the target Tera Term window.
+
+  Configuration options:
+
+  CONFIG_EXAMPLES_USBTERM_BUILTIN - Build the usbterm example as an NSH
+    built-in command.  NOTE:  This is not fully functional as of this
+    writing.. It should work, but there is no mechanism in place yet
+    to exit the USB terminal program and return to NSH.
+  CONFIG_EXAMPLES_USBTERM_DEVINIT - If defined, then the example will
+    call a user provided function as part of its initialization:
+       int usbterm_devinit(void);
+    And another user provided function at termination:
+       void usbterm_devuninit(void);
+  CONFIG_EXAMPLES_USBTERM_BUFLEN - The size of the input and output
+    buffers used for receiving data. Default 256 bytes.
+
+  If CONFIG_USBDEV_TRACE is enabled (or CONFIG_DEBUG and CONFIG_DEBUG_USB, or
+  CONFIG_USBDEV_TRACE), then the example code will also manage the USB trace
+  output.  The amount of trace output can be controlled using:
+
+  CONFIG_EXAMPLES_USBTERM_TRACEINIT
+    Show initialization events
+  CONFIG_EXAMPLES_USBTERM_TRACECLASS
+    Show class driver events
+  CONFIG_EXAMPLES_USBTERM_TRACETRANSFERS
+    Show data transfer events
+  CONFIG_EXAMPLES_USBTERM_TRACECONTROLLER
+    Show controller events
+  CONFIG_EXAMPLES_USBTERM_TRACEINTERRUPTS
+    Show interrupt-related events.
+
+  NOTE:  By default, USBterm uses readline to get data from stdin.  So your
+  appconfig file must have the following build path:
+
+    CONFIGURED_APPS += system/readline
+
+  NOTE: If you use the USBterm task over a telnet NSH connection, then you
+  should set the following configuration item:
+
+    CONFIG_EXAMPLES_USBTERM_FGETS=y
+
+  By default, the USBterm client will use readline() to get characters from
+  the console.  Readline includes and command-line editor and echos
+  characters received in stdin back through stdout.  Neither of these
+  behaviors are desire-able if Telnet is used.
+
+  Error results are always shown in the trace output
+
+  Other relevant configuration options:  CONFIG_CDCACM selected by the
+  Prolifics emulation (not defined) and the CDC serial implementation
+  (when defined). CONFIG_USBDEV_TRACE_INITIALIDSET.
+
+examples/watchdog
+^^^^^^^^^^^^^^^^^
+
+  A simple test of a watchdog timer driver.  Initializes starts the watchdog
+  timer.  It pings the watchdog timer for a period of time then lets the
+  watchdog timer expire... resetting the CPU is successful.  This
+  example can ONLY be built as an NSH built-in function.
+
+  This test depends on these specific Watchdog/NSH configurations settings (your
+  specific watchdog hardware settings might require additional settings).
+
+    CONFIG_WATCHDOG- Enables watchdog timer support support.
+    CONFIG_NSH_BUILTIN_APPS - Build the watchdog time test as an NSH
+      built-in function. Default: Not built!  The example can only be used
+      as an NSH built-in application
+ 
+  Specific configuration options for this example include:
+ 
+    CONFIG_EXAMPLES_WATCHDOG_DEVPATH - The path to the Watchdog device.
+      Default: /dev/watchdog0
+    CONFIG_EXAMPLES_WATCHDOG_PINGTIME - Time in milliseconds that the example
+      will ping the watchdog before letting the watchdog expire. Default: 5000
+      milliseconds
+    CONFIG_EXAMPLES_WATCHDOG_PINGDELAY - Time delay between pings in
+      milliseconds. Default: 500 milliseconds.
+    CONFIG_EXAMPLES_WATCHDOG_TIMEOUT - The watchdog timeout value in
+      milliseconds before the watchdog timer expires.  Default:  2000
+      milliseconds.
+
+examples/wget
+^^^^^^^^^^^^^
+
+  A simple web client example.  It will obtain a file from a server using the HTTP
+  protocol.  Settings unique to this example include:
+
+    CONFIG_EXAMPLE_WGET_URL       - The URL of the file to get
+    CONFIG_EXAMPLE_WGET_NOMAC     - (May be defined to use software assigned MAC)
+    CONFIG_EXAMPLE_WGET_IPADDR    - Target IP address
+    CONFIG_EXAMPLE_WGET_DRIPADDR  - Default router IP addess
+    CONFIG_EXAMPLE_WGET_NETMASK   - Network mask
+
+  This example uses netutils/webclient.  Additional configuration settings apply
+  to that code as follows (but built-in defaults are probably OK):
+
+    CONFIG_WEBCLIENT_GETMIMETYPE, CONFIG_WEBCLIENT_MAXHTTPLINE,
+    CONFIG_WEBCLIENT_MAXMIMESIZE, CONFIG_WEBCLIENT_MAXHOSTNAME,
+    CONFIG_WEBCLIENT_MAXFILENAME
+
+  Of course, the example also requires other settings including CONFIG_NET and
+  CONFIG_NET_TCP.  The example also uses the uIP resolver which requires CONFIG_UDP.
+
+  WARNNG: As of this writing, wget is untested on the target platform.  At present
+  it has been tested only in the host-based configuration described in the following
+  note.  The primary difference is that the target version will rely on the also
+  untested uIP name resolver.
+
+  NOTE: For test purposes, this example can be built as a host-based wget function.
+  This can be built as follows:
+
+    cd examples/wget
+    make -f Makefile.host
+
+  Applications using this example will need to provide an appconfig
+  file in the configuration driver with instruction to build applications
+  like:
+
+    CONFIGURED_APPS += uiplib
+    CONFIGURED_APPS += resolv
+    CONFIGURED_APPS += webclient
+
+examples/xmlrpc
+
+  This example exercises the "Embeddable Lightweight XML-RPC Server" which
+  is discussed at:
+
+    http://www.drdobbs.com/web-development/an-embeddable-lightweight-xml-rpc-server/184405364
+
+  Configuration options:
+
+    CONFIG_EXAMPLES_XMLRPC_BUFFERSIZE - HTTP buffer size. Default 1024
+    CONFIG_EXAMPLES_XMLRPC_DHCPC - Use DHCP Client.  Default n. Ignored
+      if CONFIG_NSH_BUILTIN_APPS is selected.
+    CONFIG_EXAMPLES_XMLRPC_NOMAC - Use Canned MAC Address. Defaul n. Ignored
+      if CONFIG_NSH_BUILTIN_APPS is selected.
+    CONFIG_EXAMPLES_XMLRPC_IPADDR - Target IP address. Default 0x0a000002.
+      Ignored if CONFIG_NSH_BUILTIN_APPS is selected.
+    CONFIG_EXAMPLES_XMLRPC_DRIPADDR - Default Router IP address (Gateway).
+      Default 0x0a000001. Ignored if CONFIG_NSH_BUILTIN_APPS is selected.
+    CONFIG_EXAMPLES_XMLRPC_NETMASK - Network Mask.  Default 0xffffff00
+      Ignored if CONFIG_NSH_BUILTIN_APPS is selected.

+hello.pas
+
+  This is a sample "Hello, World!" Pascal Program
+
+hello.pex
+
+  This is the compiled, linked P-Code executable that results
+  when hello.pas is compiled.
+
+hello.h
+
+  This file defines an initialized C array holds a copy of
+  hello.pex.  This file as created by:
+
+    xxd -i hello.pex >hello.h
+
+mkhello.sh
+
+  This is a scripts that can be used to rebuild both hello.pex
+  and hello.h.
+
+device.c
+
+  The hello.pex file must be provided to the interpreter as a file
+  in the file system.  Normally this would be done using real storage
+  medium.  In this example, we will use device.c:
+
+  device.c implements a simple device driver.  Reads from this device
+  will access the in-memory copy of hello.pex  This device driver is
+  registered as /dev/pashello in the pseudo filesystem.

+This directory contains a functional port of the tiny uIP shell.  In the
+NuttX environment, the NuttShell (at apps/nshlib) supercedes this tiny
+shell and also supports telnetd.
+
+This example is retained here for reference purposes only.

+  "who for so many years has committed Germany to democracy and freedom and "
+  "progress, and to come here in the company of my fellow American, General Clay, "
+  "who has been in this city during its great moments of crisis and will come "
+  "again if ever needed.\n"
+  "Two thousand years ago the proudest boast was \"civis Romanus sum.\" Today, "
+  "in the world of freedom, the proudest boast is \"Ich bin ein Berliner.\"\r\""
+  "I appreciate my interpreter translating my German!\n"
+  "There are many people in the world who really don't understand, or say they "
+  "don't, what is the great issue between the free world and the Communist world. "
+  "Let them come to Berlin. There are some who say that communism is the wave of "
+  "the future. Let them come to Berlin. And there are some who say in Europe and "
+  "elsewhere we can work with the Communists. Let them come to Berlin. And there "
+  "are even a few who say that it is true that communism is an evil system, but it "
+  "permits us to make economic progress. Lass' sie nach Berlin kommen. Let them "
+  "come to Berlin.\n"
+  "Freedom has many difficulties and democracy is not perfect, but we have never "
+  "had to put a wall up to keep our people in, to prevent them from leaving us. I "
+  "want to say, on behalf of my countrymen, who live many miles away on the other "
+  "side of the Atlantic, who are far distant from you, that they take the greatest "
+  "pride that they have been able to share with you, even from a distance, the "
+  "story of the last 18 years. I know of no town, no city, that has been besieged "
+  "for 18 years that still lives with the vitality and the force, and the hope and "
+  "the determination of the city of West Berlin. While the wall is the most obvious "
+  "and vivid demonstration of the failures of the Communist system, for all the "
+  "world to see, we take no satisfaction in it, for it is, as your Mayor has said, "
+  "an offense not only against history but an offense against humanity, separating "
+  "families, dividing husbands and wives and brothers and sisters, and dividing a "
+  "people who wish to be joined together.\n"
+  "What is true of this city is true of Germany--real, lasting peace in Europe can "
+  "never be assured as long as one German out of four is denied the elementary "
+  "right of free men, and that is to make a free choice. In 18 years of peace and "
+  "good faith, this generation of Germans has earned the right to be free, "
+  "including the right to unite their families and their nation in lasting peace, "
+  "with good will to all people. You live in a defended island of freedom, but "
+  "your life is part of the main. So let me ask you as I close, to lift your eyes "
+  "beyond the dangers of today, to the hopes of tomorrow, beyond the freedom merely "
+  "of this city of Berlin, or your country of Germany, to the advance of freedom "
+  "everywhere, beyond the wall to the day of peace with justice, beyond yourselves "
+  "and ourselves to all mankind.\n"
+  "Freedom is indivisible, and when one man is enslaved, all are not free. When all "
+  "are free, then we can look forward to that day when this city will be joined as "
+  "one and this country and this great Continent of Europe in a peaceful and hopeful "
+  "globe. When that day finally comes, as it will, the people of West Berlin can take "
+  "sober satisfaction in the fact that they were in the front lines for almost two "
+  "decades.\n"
+  "All free men, wherever they may live, are citizens of Berlin, and, therefore, "
+  "as a free man, I take pride in the words \"Ich bin ein Berliner.\"\n"
