examples ^^^^^^^^ The examples directory contains several sample applications that can be linked with nuttx. The specific example is selected in the configs//defconfig file via the CONFIG_EXAMPLE setting. For example, CONFIG_EXAMPLE=ostest Selects the examples/ostest example. 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//defconfig file: * CONFIG_OSTEST_STACKSIZE Used to create the ostest task. Default is 8192. examples/nsh ^^^^^^^^^^^^ This directory contains the NuttShell (NSH). This is a simple shell-like application. With some additional development, NSH will someday be a great NuttX application debugger. At present, NSH supports the following commands: Command Depends on Configuration ---------- -------------------------- cat CONFIG_NFILE_DESCRIPTORS > 0 cp CONFIG_NFILE_DESCRIPTORS > 0 echo -- exec -- exit -- help -- ifconfig CONFIG_NET && CONFIG_NSOCKET_DESCRIPTORS > 0 ls CONFIG_NFILE_DESCRIPTORS > 0 mkdir !CONFIG_DISABLE_MOUNTPOINT && CONFIG_NFILE_DESCRIPTORS > 0 mount !CONFIG_DISABLE_MOUNTPOINT && CONFIG_NFILE_DESCRIPTORS > 0 ps -- set !CONFIG_DISABLE_ENVIRON rm !CONFIG_DISABLE_MOUNTPOINT && CONFIG_NFILE_DESCRIPTORS > 0 rmdir !CONFIG_DISABLE_MOUNTPOINT && CONFIG_NFILE_DESCRIPTORS > 0 umount !CONFIG_DISABLE_MOUNTPOINT && CONFIG_NFILE_DESCRIPTORS > 0 unset !CONFIG_DISABLE_ENVIRON Other behavior of NSH can be modified with the following settings in the configs//defconfig file: * CONFIG_NSH_IOBUFFERSIZE Size of a static I/O buffer used for file access (ignored if there is no filesystem). * CONFIG_NSH_STRERROR strerror(errno) makes more readable output but strerror() is very large and will not be used unless this setting is 'y' * CONFIG_EXAMPLES_NSH_TELNET By default, NSH is configured to use the serial console. If CONFIG_EXAMPLES_NSH_TELNET is set to 'y', then a TELENET server front-end is selected. When this option is provided, you must log into NuttX remotely using telnet in order to access NSH. If CONFIG_EXAMPLES_NSH_TELNET is selected, then there some other configuration settings that apply: * CONFIG_EXAMPLES_NSH_IOBUFFER_SIZE Determines the size of the I/O buffer to use for sending/ receiving TELNET commands/reponses * CONFIG_EXAMPLES_NSH_CMD_SIZE The size of one parsed NSH command * CONFIG_EXAMPLES_NSH_STACKSIZE The stack size to use when spawning new threads as new TELNET connections are established. * CONFIG_EXAMPLES_NSH_DHCPC Obtain the the IP address via DHCP. * CONFIG_EXAMPLES_NSH_IPADDR If CONFIG_EXAMPLES_NSH_DHCPC is NOT set, then the static IP address must be provided. * CONFIG_EXAMPLES_NSH_DRIPADDR Default router IP address * CONFIG_EXAMPLES_NSH_NETMASK Network mask * CONFIG_EXAMPLES_NSH_NOMAC Set if your ethernet hardware has no built-in MAC address. If set, a bogus MAC will be assigned. examples/mount ^^^^^^^^^^^^^^ This contains a simple test of filesystem mountpoints. examples/null ^^^^^^^^^^^^^ This is the do nothing application. It is only used for bringing up new NuttX architectures. examples/uip ^^^^^^^^^^^^ This is a port of uIP example application. It includes conditionally compiled logic to exercise the uIP webserver, webclient, telnet, smtp, dncpc, and resolver. examples/netttest ^^^^^^^^^^^^^^^^^ This is a simple network test for verifying client- and server- functionality in a TCP/IP connection. examples/udp ^^^^^^^^^^^^ This is a simple network test for verifying client- and server- functionality over UDP. examples/pashello ^^^^^^^^^^^^^^^^^ This is "Hello, World" implemented via the Pascal P-Code interpreter
