- *
- * PX4IO Serial interface notes
- * ----------------------------
- *
- * The MSB of the page number is used to distinguish between read and
- * write operations. If set, the operation is a write and additional 
- * data is expected to follow in the packet as for I2C writes.
- *
- * If clear, the packet is expected to contain a single byte giving the
- * number of registers to be read. PX4IO will respond with a packet containing
- * the same header (page, offset) and the requested data.
- *
- * If a read is requested when PX4IO does not have buffer space to store
- * the reply, the request will be dropped. PX4IO is always configured with
- * enough space to receive one full-sized write and one read request, and
- * to send one full-sized read response.

 on the FMU side.

Still needs serial init and some more testing/config on the FMU side, but closer to being ready to test.

From 9d6ec6b3655fcd902be7a7fe4f2a24033c714afb Mon Sep 17 00:00:00 2001
From: px4dev <px4@purgatory.org>
Date: Fri, 2 Aug 2013 22:34:55 -0700
Subject: Restructure things so that the PX4 configs move out of the NuttX
 tree, and most of the PX4-specific board configuration data moves out of the
 config and into the board driver.

Rename some directories that got left behind in the great board renaming.

+
+Development Environment
+=======================
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment because the Raisonance R-Link emulatator and some RIDE7 development tools
+  were used and those tools works only under Windows.
+
+GNU Toolchain Options
+=====================
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. Raisonance GNU toolchain, or
+  4. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery, devkitARM or Raisonance GNU toolchain, you simply need to
+  add one of the following configuration options to your .config (or defconfig)
+  file:
+
+    CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_STM32_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_STM32_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_STM32_RAISONANCE=y     : Raisonance RIDE7 under Windows
+    CONFIG_STM32_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_STM32_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows), devkitARM, and Raisonance toolchains are
+  Windows native toolchains.  The CodeSourcey (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+====
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project (There is a simple RIDE project
+  in the RIDE subdirectory).
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/stm32,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/stm32/stm32_vectors.S.  With RIDE, I have to build NuttX
+  one time from the Cygwin command line in order to obtain the pre-built
+  startup object needed by RIDE.
+
+NuttX buildroot Toolchain
+=========================
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh stm3210e-eval/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+DFU and JTAG
+============
+
+  Enbling Support for the DFU Bootloader
+  --------------------------------------
+  The linker files in these projects can be configured to indicate that you
+  will be loading code using STMicro built-in USB Device Firmware Upgrade (DFU)
+  loader or via some JTAG emulator.  You can specify the DFU bootloader by
+  adding the following line:
+
+    CONFIG_STM32_DFU=y
+
+  to your .config file. Most of the configurations in this directory are set
+  up to use the DFU loader.
+
+  If CONFIG_STM32_DFU is defined, the code will not be positioned at the beginning
+  of FLASH (0x08000000) but will be offset to 0x08003000.  This offset is needed
+  to make space for the DFU loader and 0x08003000 is where the DFU loader expects
+  to find new applications at boot time.  If you need to change that origin for some
+  other bootloader, you will need to edit the file(s) ld.script.dfu for each
+  configuration.
+
+  The DFU SE PC-based software is available from the STMicro website,
+  http://www.st.com.  General usage instructions:
+  
+  1. Convert the NuttX Intel Hex file (nuttx.ihx) into a special DFU
+     file (nuttx.dfu)... see below for details.
+  2. Connect the STM3210E-EVAL board to your computer using a USB
+     cable.
+  3. Start the DFU loader on the STM3210E-EVAL board.  You do this by
+     resetting the board while holding the "Key" button.  Windows should
+     recognize that the DFU loader has been installed.
+  3. Run the DFU SE program to load nuttx.dfu into FLASH.
+
+  What if the DFU loader is not in FLASH?  The loader code is available
+  inside of the Demo dirctory of the USBLib ZIP file that can be downloaded
+  from the STMicro Website.  You can build it using RIDE (or other toolchains);
+  you will need a JTAG emulator to burn it into FLASH the first time.
+
+  In order to use STMicro's built-in DFU loader, you will have to get
+  the NuttX binary into a special format with a .dfu extension.  The
+  DFU SE PC_based software installation includes a file "DFU File Manager"
+  conversion program that a file in Intel Hex format to the special DFU
+  format.  When you successfully build NuttX, you will find a file called
+  nutt.ihx in the top-level directory.  That is the file that you should
+  provide to the DFU File Manager.  You will need to rename it to nuttx.hex
+  in order to find it with the DFU File Manager. You will end up with
+  a file called nuttx.dfu that you can use with the STMicro DFU SE program.
+
+  Enabling JTAG
+  -------------
+  If you are not using the DFU, then you will probably also need to enable
+  JTAG support.  By default, all JTAG support is disabled but there NuttX
+  configuration options to enable JTAG in various different ways.
+
+  These configurations effect the setting of the SWJ_CFG[2:0] bits in the AFIO
+  MAPR register.  These bits are used to configure the SWJ and trace alternate function I/Os. The SWJ (SerialWire JTAG) supports JTAG or SWD access to the
+  Cortex debug port.  The default state in this port is for all JTAG support
+  to be disable.
+
+  CONFIG_STM32_JTAG_FULL_ENABLE - sets SWJ_CFG[2:0] to 000 which enables full
+    SWJ (JTAG-DP + SW-DP)
+
+  CONFIG_STM32_JTAG_NOJNTRST_ENABLE - sets SWJ_CFG[2:0] to 001 which enable
+    full SWJ (JTAG-DP + SW-DP) but without JNTRST.
+
+  CONFIG_STM32_JTAG_SW_ENABLE - sets SWJ_CFG[2:0] to 010 which would set JTAG-DP
+    disabled and SW-DP enabled
+
+  The default setting (none of the above defined) is SWJ_CFG[2:0] set to 100
+  which disable JTAG-DP and SW-DP.
+
+OpenOCD
+=======
+
+I have also used OpenOCD with the STM3210E-EVAL.  In this case, I used
+the Olimex USB ARM OCD.  See the script in configs/stm3210e-eval/tools/oocd.sh
+for more information.  Using the script:
+
+1) Start the OpenOCD GDB server
+
+   cd <nuttx-build-directory>
+   configs/stm3210e-eval/tools/oocd.sh $PWD
+
+2) Load Nuttx
+
+   cd <nuttx-built-directory>
+   arm-none-eabi-gdb nuttx
+   gdb> target remote localhost:3333
+   gdb> mon reset
+   gdb> mon halt
+   gdb> load nuttx
+
+3) Running NuttX
+
+   gdb> mon reset
+   gdb> c
+
+LEDs
+====
+
+The STM3210E-EVAL board has four LEDs labeled LD1, LD2, LD3 and LD4 on the
+board.. These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
+defined.  In that case, the usage by the board port is defined in
+include/board.h and src/up_leds.c. The LEDs are used to encode OS-related
+events as follows:
+
+    SYMBOL           Meaning                 LED1* LED2  LED3  LED4
+    ---------------- ----------------------- ----- ----- ----- -----
+    LED_STARTED      NuttX has been started  ON    OFF   OFF   OFF
+    LED_HEAPALLOCATE Heap has been allocated OFF   ON    OFF   OFF
+    LED_IRQSENABLED  Interrupts enabled      ON    ON    OFF   OFF
+    LED_STACKCREATED Idle stack created      OFF   OFF   ON    OFF
+    LED_INIRQ        In an interrupt**       ON    N/C   N/C   OFF
+    LED_SIGNAL       In a signal handler***  N/C   ON    N/C   OFF
+    LED_ASSERTION    An assertion failed     ON    ON    N/C   OFF
+    LED_PANIC        The system has crashed  N/C   N/C   N/C   ON
+    LED_IDLE         STM32 is is sleep mode  (Optional, not used)
+
+  * If LED1, LED2, LED3 are statically on, then NuttX probably failed to boot
+    and these LEDs will give you some indication of where the failure was
+ ** The normal state is LED3 ON and LED1 faintly glowing.  This faint glow
+    is because of timer interupts that result in the LED being illuminated
+    on a small proportion of the time.
+*** LED2 may also flicker normally if signals are processed.
+
+Temperature Sensor
+==================
+
+Support for the on-board LM-75 temperature sensor is available.  This supported
+has been verified, but has not been included in any of the available the
+configurations.  To set up the temperature sensor, add the following to the
+NuttX configuration file
+
+  CONFIG_I2C=y
+  CONFIG_I2C_LM75=y
+
+Then you can implement logic like the following to use the temperature sensor:
+
+  #include <nuttx/sensors/lm75.h>
+  #include <arch/board/board.h>
+
+  ret =  stm32_lm75initialize("/dev/temp");       /* Register the temperature sensor */
+  fd = open("/dev/temp", O_RDONLY);               /* Open the temperature sensor device */
+  ret = ioctl(fd, SNIOC_FAHRENHEIT, 0);           /* Select Fahrenheit */
+  bytesread = read(fd, buffer, 8*sizeof(b16_t));  /* Read temperature samples */
+
+More complex temperature sensor operations are also available.  See the IOCTAL
+commands enumerated in include/nuttx/sensors/lm75.h.  Also read the descriptions
+of the stm32_lm75initialize() and stm32_lm75attach() interfaces in the
+arch/board/board.h file (sames as configs/stm3210e-eval/include/board.h).
+
+RTC
+===
+
+  The STM32 RTC may configured using the following settings.
+
+    CONFIG_RTC - Enables general support for a hardware RTC. Specific
+      architectures may require other specific settings.
+    CONFIG_RTC_HIRES - The typical RTC keeps time to resolution of 1
+      second, usually supporting a 32-bit time_t value.  In this case,
+      the RTC is used to &quot;seed&quot; the normal NuttX timer and the
+      NuttX timer provides for higher resoution time. If CONFIG_RTC_HIRES
+      is enabled in the NuttX configuration, then the RTC provides higher
+      resolution time and completely replaces the system timer for purpose of
+      date and time.
+      CONFIG_RTC_FREQUENCY - If CONFIG_RTC_HIRES is defined, then the
+      frequency of the high resolution RTC must be provided.  If CONFIG_RTC_HIRES
+      is not defined, CONFIG_RTC_FREQUENCY is assumed to be one.
+    CONFIG_RTC_ALARM - Enable if the RTC hardware supports setting of an alarm. 
+      A callback function will be executed when the alarm goes off
+
+  In hi-res mode, the STM32 RTC operates only at 16384Hz.  Overflow interrupts
+  are handled when the 32-bit RTC counter overflows every 3 days and 43 minutes.
+  A BKP register is incremented on each overflow interrupt creating, effectively,
+  a 48-bit RTC counter.
+
+  In the lo-res mode, the RTC operates at 1Hz.  Overflow interrupts are not handled
+  (because the next overflow is not expected until the year 2106.
+
+   WARNING:  Overflow interrupts are lost whenever the STM32 is powered down.  The
+   overflow interrupt may be lost even if the STM32 is powered down only momentarily.
+   Therefore hi-res solution is only useful in systems where the power is always on.
+
+STM3210E-EVAL-specific Configuration Options
+============================================
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+       be set to:
+
+       CONFIG_ARCH=arm
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_ARM=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_CORTEXM3=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=stm32
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip:
+
+       CONFIG_ARCH_CHIP_STM32F103ZET6
+
+    CONFIG_ARCH_BOARD_STM32_CUSTOM_CLOCKCONFIG - Enables special STM32 clock
+       configuration features.
+
+       CONFIG_ARCH_BOARD_STM32_CUSTOM_CLOCKCONFIG=n
+ 
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=stm3210e_eval (for the STM3210E-EVAL development board)
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_STM3210E_EVAL=y
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+       CONFIG_DRAM_SIZE=0x00010000 (64Kb)
+
+    CONFIG_DRAM_START - The start address of installed DRAM
+

+
+       CONFIG_DRAM_END=(CONFIG_DRAM_START+CONFIG_DRAM_SIZE)
+
+    CONFIG_ARCH_IRQPRIO - The STM32F103Z supports interrupt prioritization
+
+       CONFIG_ARCH_IRQPRIO=y
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+        stack in bytes.  If not defined, the user task stacks will be
+      used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.

+  Timer and I2C devices may need to the following to force power to be applied
+  unconditionally at power up.  (Otherwise, the device is powered when it is
+  initialized).
+
+    CONFIG_STM32_FORCEPOWER
+
+  Timer devices may be used for different purposes.  One special purpose is
+  to generate modulated outputs for such things as motor control.  If CONFIG_STM32_TIMn
+  is defined (as above) then the following may also be defined to indicate that
+  the timer is intended to be used for pulsed output modulation, ADC conversion,
+  or DAC conversion.  Note that ADC/DAC require two definition:  Not only do you have
+  to assign the timer (n) for used by the ADC or DAC, but then you also have to
+  configure which ADC or DAC (m) it is assigned to.
+
+    CONFIG_STM32_TIMn_PWM   Reserve timer n for use by PWM, n=1,..,8
+    CONFIG_STM32_TIMn_ADC   Reserve timer n for use by ADC, n=1,..,8

+    CONFIG_STM32_TIMn_DACm  Reserve timer n to trigger DACm, n=1,..,8, m=1,..,2
+
+  For each timer that is enabled for PWM usage, we need the following additional
+  configuration settings:
+
+    CONFIG_STM32_TIMx_CHANNEL - Specifies the timer output channel {1,..,4}
+ 
+  NOTE: The STM32 timers are each capable of generating different signals on
+  each of the four channels with different duty cycles.  That capability is
+  not supported by this driver:  Only one output channel per timer.

+      support. Non-interrupt-driven, poll-waiting is recommended if the
+      interrupt rate would be to high in the interrupt driven case.
+    CONFIG_STM32_SPI_DMA - Use DMA to improve SPI transfer performance.
+      Cannot be used with CONFIG_STM32_SPI_INTERRUPT.
+
+    CONFIG_SDIO_DMA - Support DMA data transfers.  Requires CONFIG_STM32_SDIO
+      and CONFIG_STM32_DMA2.
+    CONFIG_SDIO_PRI - Select SDIO interrupt prority.  Default: 128
+    CONFIG_SDIO_DMAPRIO - Select SDIO DMA interrupt priority. 
+      Default:  Medium
+    CONFIG_SDIO_WIDTH_D1_ONLY - Select 1-bit transfer mode.  Default:
+      4-bit transfer mode.
+
+  STM3210E-EVAL CAN Configuration
+
+    CONFIG_CAN - Enables CAN support (one or both of CONFIG_STM32_CAN1 or
+      CONFIG_STM32_CAN2 must also be defined)
+    CONFIG_CAN_EXTID - Enables support for the 29-bit extended ID.  Default
+      Standard 11-bit IDs.

+    CONFIG_CAN_REGDEBUG - If CONFIG_DEBUG is set, this will generate an
+      dump of all CAN registers.
+
+  STM3210E-EVAL LCD Hardware Configuration
+
+    CONFIG_LCD_LANDSCAPE - Define for 320x240 display "landscape"
+      support. Default is this 320x240 "landscape" orientation
+      (this setting is informative only... not used).
+    CONFIG_LCD_PORTRAIT - Define for 240x320 display "portrait"
+      orientation support.  In this orientation, the STM3210E-EVAL's
+      LCD ribbon cable is at the bottom of the display. Default is
+      320x240 "landscape" orientation.
+    CONFIG_LCD_RPORTRAIT - Define for 240x320 display "reverse
+      portrait" orientation support.  In this orientation, the
+      STM3210E-EVAL's LCD ribbon cable is at the top of the display.
+      Default is 320x240 "landscape" orientation.
+    CONFIG_LCD_BACKLIGHT - Define to support a backlight.
+    CONFIG_LCD_PWM - If CONFIG_STM32_TIM1 is also defined, then an
+      adjustable backlight will be provided using timer 1 to generate
+      various pulse widthes.  The granularity of the settings is
+      determined by CONFIG_LCD_MAXPOWER.  If CONFIG_LCD_PWM (or
+      CONFIG_STM32_TIM1) is not defined, then a simple on/off backlight
+      is provided.
+    CONFIG_LCD_RDSHIFT - When reading 16-bit gram data, there appears
+      to be a shift in the returned data.  This value fixes the offset.
+      Default 5.
+
+    The LCD driver dynamically selects the LCD based on the reported LCD
+    ID value.  However, code size can be reduced by suppressing support for
+    individual LCDs using:
+
+    CONFIG_STM32_AM240320_DISABLE
+    CONFIG_STM32_SPFD5408B_DISABLE
+    CONFIG_STM32_R61580_DISABLE
+
+Configurations
+==============
+
+Each STM3210E-EVAL configuration is maintained in a sudirectory and
+can be selected as follow:
+
+    cd tools
+    ./configure.sh stm3210e-eval/<subdir>
+    cd -
+    . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  buttons:
+  --------
+
+    Uses apps/examples/buttons to exercise STM3210E-EVAL buttons and
+    button interrupts.
+ 
+    CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+
+  composite
+  ---------
+
+    This configuration exercises a composite USB interface consisting
+    of a CDC/ACM device and a USB mass storage device.  This configuration
+    uses apps/examples/composite.
+
+  nsh and nsh2:
+  ------------
+    Configure the NuttShell (nsh) located at examples/nsh.
+
+    Differences between the two NSH configurations:
+
+    =========== ======================= ================================
+                nsh                     nsh2
+    =========== ======================= ================================

+                                        apps/examples/usbstorage (5)
+    =========== ======================= ================================
+
+    (1) You will probably need to modify nsh/setenv.sh or nsh2/setenv.sh
+        to set up the correct PATH variable for whichever toolchain you
+        may use.
+    (2) Since DfuSe is assumed, this configuration may only work under
+        Cygwin without modification.
+    (3) When any other device other than /dev/console is used for a user
+        interface, (1) linefeeds (\n) will not be expanded to carriage return
+        / linefeeds \r\n). You will need to configure your terminal program
+        to account for this. And (2) input is not automatically echoed so
+        you will have to turn local echo on.
+    (4) Microsoft holds several patents related to the design of
+        long file names in the FAT file system.  Please refer to the
+        details in the top-level COPYING file.  Please do not use FAT
+        long file name unless you are familiar with these patent issues.
+    (5) When built as an NSH add-on command (CONFIG_EXAMPLES_USBMSC_BUILTIN=y),
+        Caution should be used to assure that the SD drive 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.
+
+  nx:
+  ---
+    An example using the NuttX graphics system (NX).  This example
+    focuses on general window controls, movement, mouse and keyboard
+    input.
+
+    CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_LCD_RPORTRAIT=y        : 240x320 reverse portrait
+
+  nxlines:
+  ------
+    Another example using the NuttX graphics system (NX).   This
+    example focuses on placing lines on the background in various
+    orientations.
+
+    CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_LCD_RPORTRAIT=y        : 240x320 reverse portrait
+
+  nxtext:
+  ------
+    Another example using the NuttX graphics system (NX).   This
+    example focuses on placing text on the background while pop-up
+    windows occur.  Text should continue to update normally with
+    or without the popup windows present.
+
+    CONFIG_STM32_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin
+    CONFIG_LCD_RPORTRAIT=y        : 240x320 reverse portrait
+
+    NOTE:  When I tried building this example with the CodeSourcery
+    tools, I got a hardfault inside of its libgcc.  I haven't
+    retested since then, but beware if you choose to change the
+    toolchain.
+
+  ostest:
+  ------
+    This configuration directory, performs a simple OS test using
+    examples/ostest.  By default, this project assumes that you are
+    using the DFU bootloader.
+
+    CONFIG_STM32_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin
+
+  RIDE
+  ----
+    This configuration builds a trivial bring-up binary.  It is
+    useful only because it words with the RIDE7 IDE and R-Link debugger.
+
+    CONFIG_STM32_RAISONANCE=y     : Raisonance RIDE7 under Windows
+
+  usbserial:
+  ---------
+    This configuration directory exercises the USB serial class
+    driver at examples/usbserial.  See examples/README.txt for
+    more information.
+
+    CONFIG_STM32_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin
+
+    USB debug output can be enabled as by changing the following
+    settings in the configuration file:
+
+    -CONFIG_DEBUG=n
+    -CONFIG_DEBUG_VERBOSE=n
+    -CONFIG_DEBUG_USB=n
+    +CONFIG_DEBUG=y
+    +CONFIG_DEBUG_VERBOSE=y
+    +CONFIG_DEBUG_USB=y
+
+    -CONFIG_EXAMPLES_USBSERIAL_TRACEINIT=n
+    -CONFIG_EXAMPLES_USBSERIAL_TRACECLASS=n
+    -CONFIG_EXAMPLES_USBSERIAL_TRACETRANSFERS=n
+    -CONFIG_EXAMPLES_USBSERIAL_TRACECONTROLLER=n
+    -CONFIG_EXAMPLES_USBSERIAL_TRACEINTERRUPTS=n
+    +CONFIG_EXAMPLES_USBSERIAL_TRACEINIT=y
+    +CONFIG_EXAMPLES_USBSERIAL_TRACECLASS=y
+    +CONFIG_EXAMPLES_USBSERIAL_TRACETRANSFERS=y
+    +CONFIG_EXAMPLES_USBSERIAL_TRACECONTROLLER=y
+    +CONFIG_EXAMPLES_USBSERIAL_TRACEINTERRUPTS=y
+
+    By default, the usbserial example uses the Prolific PL2303
+    serial/USB converter emulation.  The example can be modified
+    to use the CDC/ACM serial class by making the following changes
+    to the configuration file:
+
+    -CONFIG_PL2303=y
+    +CONFIG_PL2303=n
+
+    -CONFIG_CDCACM=n
+    +CONFIG_CDCACM=y
+
+    The example can also be converted to use the alternative
+    USB serial example at apps/examples/usbterm by changing the 
+    following:
+
+    -CONFIGURED_APPS += examples/usbserial
+    +CONFIGURED_APPS += examples/usbterm
+
+    In either the original appconfig file (before configuring)
+    or in the final apps/.config file (after configuring).
+
+  usbstorage:
+  ----------
+    This configuration directory exercises the USB mass storage
+    class driver at examples/usbstorage.  See examples/README.txt for
+    more information.

+#   and stderr.
+# CONFIG_SDCLONE_DISABLE. Disable cloning of all socket
+#   desciptors by task_create() when a new task is started. If
+#   set, all sockets will appear to be closed in the new task.
+# CONFIG_SCHED_WORKQUEUE.  Create a dedicated "worker" thread to
+#  handle delayed processing from interrupt handlers.  This feature
+#  is required for some drivers but, if there are not complaints,
+#  can be safely disabled.  The worker thread also performs
+#  garbage collection -- completing any delayed memory deallocations
+#  from interrupt handlers.  If the worker thread is disabled,
+#  then that clean will be performed by the IDLE thread instead
+#  (which runs at the lowest of priority and may not be appropriate
+#  if memory reclamation is of high priority).  If CONFIG_SCHED_WORKQUEUE

+# CONFIG_SCHED_WORKPRIORITY - The execution priority of the worker
+#  thread.  Default: 50

From e931d3b9cda723d63bf352ca866dc499d8df21f5 Mon Sep 17 00:00:00 2001
From: px4dev <px4@purgatory.org>
Date: Sat, 3 Aug 2013 22:35:18 -0700
Subject: Add an option to the systemreset() call and to the reboot command
 (-b) to reboot into the bootloader.

The system will remain in the bootloader until it's reset, or until an upload is completed.

+/**
+   \mainpage CMSIS DSP Software Library
+   *
+   * <b>Introduction</b>
+   *
+   * This user manual describes the CMSIS DSP software library,
+   * a suite of common signal processing functions for use on Cortex-M processor based devices.
+   *
+   * The library is divided into a number of functions each covering a specific category:
+   * - Basic math functions
+   * - Fast math functions
+   * - Complex math functions
+   * - Filters
+   * - Matrix functions
+   * - Transforms
+   * - Motor control functions
+   * - Statistical functions
+   * - Support functions
+   * - Interpolation functions
+   *
+   * The library has separate functions for operating on 8-bit integers, 16-bit integers,
+   * 32-bit integer and 32-bit floating-point values.
+   *
+   * <b>Using the Library</b>
+   *
+   * The library installer contains prebuilt versions of the libraries in the <code>Lib</code> folder.
+   * - arm_cortexM4lf_math.lib (Little endian and Floating Point Unit on Cortex-M4)
+   * - arm_cortexM4bf_math.lib (Big endian and Floating Point Unit on Cortex-M4)
+   * - arm_cortexM4l_math.lib (Little endian on Cortex-M4)
+   * - arm_cortexM4b_math.lib (Big endian on Cortex-M4)
+   * - arm_cortexM3l_math.lib (Little endian on Cortex-M3)
+   * - arm_cortexM3b_math.lib (Big endian on Cortex-M3)
+   * - arm_cortexM0l_math.lib (Little endian on Cortex-M0)
+   * - arm_cortexM0b_math.lib (Big endian on Cortex-M3)
+   *
+   * The library functions are declared in the public file <code>arm_math.h</code> which is placed in the <code>Include</code> folder.
+   * Simply include this file and link the appropriate library in the application and begin calling the library functions. The Library supports single
+   * public header file <code> arm_math.h</code> for Cortex-M4/M3/M0 with little endian and big endian. Same header file will be used for floating point unit(FPU) variants.
+   * Define the appropriate pre processor MACRO ARM_MATH_CM4 or  ARM_MATH_CM3 or
+   * ARM_MATH_CM0 or ARM_MATH_CM0PLUS depending on the target processor in the application.
+   *
+   * <b>Examples</b>
+   *
+   * The library ships with a number of examples which demonstrate how to use the library functions.
+   *
+   * <b>Toolchain Support</b>
+   *
+   * The library has been developed and tested with MDK-ARM version 4.60.
+   * The library is being tested in GCC and IAR toolchains and updates on this activity will be made available shortly.
+   *
+   * <b>Building the Library</b>
+   *
+   * The library installer contains project files to re build libraries on MDK Tool chain in the <code>CMSIS\\DSP_Lib\\Source\\ARM</code> folder.
+   * - arm_cortexM0b_math.uvproj
+   * - arm_cortexM0l_math.uvproj
+   * - arm_cortexM3b_math.uvproj
+   * - arm_cortexM3l_math.uvproj
+   * - arm_cortexM4b_math.uvproj
+   * - arm_cortexM4l_math.uvproj
+   * - arm_cortexM4bf_math.uvproj
+   * - arm_cortexM4lf_math.uvproj
+   *
+   *
+   * The project can be built by opening the appropriate project in MDK-ARM 4.60 chain and defining the optional pre processor MACROs detailed above.
+   *
+   * <b>Pre-processor Macros</b>
+   *
+   * Each library project have differant pre-processor macros.
+   *
+   * - UNALIGNED_SUPPORT_DISABLE:
+   *
+   * Define macro UNALIGNED_SUPPORT_DISABLE, If the silicon does not support unaligned memory access
+   *
+   * - ARM_MATH_BIG_ENDIAN:
+   *
+   * Define macro ARM_MATH_BIG_ENDIAN to build the library for big endian targets. By default library builds for little endian targets.
+   *
+   * - ARM_MATH_MATRIX_CHECK:
+   *
+   * Define macro ARM_MATH_MATRIX_CHECK for checking on the input and output sizes of matrices
+   *
+   * - ARM_MATH_ROUNDING:
+   *
+   * Define macro ARM_MATH_ROUNDING for rounding on support functions
+   *
+   * - ARM_MATH_CMx:
+   *
+   * Define macro ARM_MATH_CM4 for building the library on Cortex-M4 target, ARM_MATH_CM3 for building library on Cortex-M3 target
+   * and ARM_MATH_CM0 for building library on cortex-M0 target, ARM_MATH_CM0PLUS for building library on cortex-M0+ target.
+   *
+   * - __FPU_PRESENT:
+   *
+   * Initialize macro __FPU_PRESENT = 1 when building on FPU supported Targets. Enable this macro for M4bf and M4lf libraries
+   *
+   * <b>Copyright Notice</b>

+/**
+ * @defgroup groupFastMath Fast Math Functions
+ * This set of functions provides a fast approximation to sine, cosine, and square root.
+ * As compared to most of the other functions in the CMSIS math library, the fast math functions

+ *

+
+/**

+ * This set of functions operates on complex data vectors.
+ * The data in the complex arrays is stored in an interleaved fashion
+ * (real, imag, real, imag, ...).
+ * In the API functions, the number of samples in a complex array refers
+ * to the number of complex values; the array contains twice this number of
+ * real values.
+ */
+
+/**
+ * @defgroup groupFilters Filtering Functions
+ */
+
+/**
+ * @defgroup groupMatrix Matrix Functions
+ *
+ * This set of functions provides basic matrix math operations.
+ * The functions operate on matrix data structures.  For example,
+ * the type
+ * definition for the floating-point matrix structure is shown
+ * below:
+ * <pre>
+ *     typedef struct
+ *     {
+ *       uint16_t numRows;     // number of rows of the matrix.
+ *       uint16_t numCols;     // number of columns of the matrix.
+ *       float32_t *pData;     // points to the data of the matrix.
+ *     } arm_matrix_instance_f32;
+ * </pre>
+ * There are similar definitions for Q15 and Q31 data types.
+ *
+ * The structure specifies the size of the matrix and then points to
+ * an array of data.  The array is of size <code>numRows X numCols</code>
+ * and the values are arranged in row order.  That is, the
+ * matrix element (i, j) is stored at:
+ * <pre>
+ *     pData[i*numCols + j]
+ * </pre>
+ *
+ * \par Init Functions
+ * There is an associated initialization function for each type of matrix
+ * data structure.
+ * The initialization function sets the values of the internal structure fields.
+ * Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
+ * and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types,  respectively.
+ *
+ * \par
+ * Use of the initialization function is optional. However, if initialization function is used
+ * then the instance structure cannot be placed into a const data section.
+ * To place the instance structure in a const data
+ * section, manually initialize the data structure.  For example:
+ * <pre>
+ * <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
+ * <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
+ * <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
+ * </pre>
+ * where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
+ * specifies the number of columns, and <code>pData</code> points to the
+ * data array.
+ *
+ * \par Size Checking
+ * By default all of the matrix functions perform size checking on the input and
+ * output matrices.  For example, the matrix addition function verifies that the
+ * two input matrices and the output matrix all have the same number of rows and
+ * columns.  If the size check fails the functions return:
+ * <pre>
+ *     ARM_MATH_SIZE_MISMATCH
+ * </pre>
+ * Otherwise the functions return
+ * <pre>
+ *     ARM_MATH_SUCCESS
+ * </pre>
+ * There is some overhead associated with this matrix size checking.
+ * The matrix size checking is enabled via the \#define
+ * <pre>
+ *     ARM_MATH_MATRIX_CHECK
+ * </pre>
+ * within the library project settings.  By default this macro is defined
+ * and size checking is enabled.  By changing the project settings and
+ * undefining this macro size checking is eliminated and the functions
+ * run a bit faster.  With size checking disabled the functions always
+ * return <code>ARM_MATH_SUCCESS</code>.

+   *
+   * A Proportional Integral Derivative (PID) controller is a generic feedback control
+   * loop mechanism widely used in industrial control systems.
+   * A PID controller is the most commonly used type of feedback controller.
+   *
+   * This set of functions implements (PID) controllers
+   * for Q15, Q31, and floating-point data types.  The functions operate on a single sample
+   * of data and each call to the function returns a single processed value.
+   * <code>S</code> points to an instance of the PID control data structure.  <code>in</code>
+   * is the input sample value. The functions return the output value.
+   *
+   * \par Algorithm:
+   * <pre>
+   *    y[n] = y[n-1] + A0 * x[n] + A1 * x[n-1] + A2 * x[n-2]
+   *    A0 = Kp + Ki + Kd
+   *    A1 = (-Kp ) - (2 * Kd )
+   *    A2 = Kd  </pre>
+   *
+   * \par
+   * where \c Kp is proportional constant, \c Ki is Integral constant and \c Kd is Derivative constant
+   *
+   * \par
+   * \image html PID.gif "Proportional Integral Derivative Controller"
+   *
+   * \par
+   * The PID controller calculates an "error" value as the difference between
+   * the measured output and the reference input.
+   * The controller attempts to minimize the error by adjusting the process control inputs.
+   * The proportional value determines the reaction to the current error,
+   * the integral value determines the reaction based on the sum of recent errors,
+   * and the derivative value determines the reaction based on the rate at which the error has been changing.
+   *
+   * \par Instance Structure
+   * The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
+   * A separate instance structure must be defined for each PID Controller.
+   * There are separate instance structure declarations for each of the 3 supported data types.
+   *
+   * \par Reset Functions
+   * There is also an associated reset function for each data type which clears the state array.
+   *
+   * \par Initialization Functions
+   * There is also an associated initialization function for each data type.
+   * The initialization function performs the following operations:
+   * - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
+   * - Zeros out the values in the state buffer.
+   *
+   * \par
+   * Instance structure cannot be placed into a const data section and it is recommended to use the initialization function.
+   *
+   * \par Fixed-Point Behavior
+   * Care must be taken when using the fixed-point versions of the PID Controller functions.
+   * In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.
+   * Refer to the function specific documentation below for usage guidelines.

+   *
+   * Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
+   * The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
+   * determines values between the grid points.
+   * Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
+   * Bilinear interpolation is often used in image processing to rescale images.
+   * The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
+   *
+   * <b>Algorithm</b>
+   * \par
+   * The instance structure used by the bilinear interpolation functions describes a two dimensional data table.
+   * For floating-point, the instance structure is defined as:
+   * <pre>
+   *   typedef struct
+   *   {
+   *     uint16_t numRows;
+   *     uint16_t numCols;
+   *     float32_t *pData;
+   * } arm_bilinear_interp_instance_f32;
+   * </pre>
+   *
+   * \par
+   * where <code>numRows</code> specifies the number of rows in the table;
+   * <code>numCols</code> specifies the number of columns in the table;
+   * and <code>pData</code> points to an array of size <code>numRows*numCols</code> values.
+   * The data table <code>pTable</code> is organized in row order and the supplied data values fall on integer indexes.
+   * That is, table element (x,y) is located at <code>pTable[x + y*numCols]</code> where x and y are integers.
+   *
+   * \par
+   * Let <code>(x, y)</code> specify the desired interpolation point.  Then define:
+   * <pre>
+   *     XF = floor(x)
+   *     YF = floor(y)
+   * </pre>
+   * \par
+   * The interpolated output point is computed as:
+   * <pre>
+   *  f(x, y) = f(XF, YF) * (1-(x-XF)) * (1-(y-YF))
+   *           + f(XF+1, YF) * (x-XF)*(1-(y-YF))
+   *           + f(XF, YF+1) * (1-(x-XF))*(y-YF)
+   *           + f(XF+1, YF+1) * (x-XF)*(y-YF)
+   * </pre>
+   * Note that the coordinates (x, y) contain integer and fractional components.
+   * The integer components specify which portion of the table to use while the
+   * fractional components control the interpolation processor.
+   *
+   * \par
+   * if (x,y) are outside of the table boundary, Bilinear interpolation returns zero output.

-/**
-   \mainpage CMSIS DSP Software Library
-   *
-   * <b>Introduction</b>
-   *
-   * This user manual describes the CMSIS DSP software library,
-   * a suite of common signal processing functions for use on Cortex-M processor based devices.
-   *
-   * The library is divided into a number of functions each covering a specific category:
-   * - Basic math functions
-   * - Fast math functions
-   * - Complex math functions
-   * - Filters
-   * - Matrix functions
-   * - Transforms
-   * - Motor control functions
-   * - Statistical functions
-   * - Support functions
-   * - Interpolation functions
-   *
-   * The library has separate functions for operating on 8-bit integers, 16-bit integers,
-   * 32-bit integer and 32-bit floating-point values.
-   *
-   * <b>Using the Library</b>
-   *
-   * The library installer contains prebuilt versions of the libraries in the <code>Lib</code> folder.
-   * - arm_cortexM4lf_math.lib (Little endian and Floating Point Unit on Cortex-M4)
-   * - arm_cortexM4bf_math.lib (Big endian and Floating Point Unit on Cortex-M4)
-   * - arm_cortexM4l_math.lib (Little endian on Cortex-M4)
-   * - arm_cortexM4b_math.lib (Big endian on Cortex-M4)
-   * - arm_cortexM3l_math.lib (Little endian on Cortex-M3)
-   * - arm_cortexM3b_math.lib (Big endian on Cortex-M3)
-   * - arm_cortexM0l_math.lib (Little endian on Cortex-M0)
-   * - arm_cortexM0b_math.lib (Big endian on Cortex-M3)
-   *
-   * The library functions are declared in the public file <code>arm_math.h</code> which is placed in the <code>Include</code> folder.
-   * Simply include this file and link the appropriate library in the application and begin calling the library functions. The Library supports single
-   * public header file <code> arm_math.h</code> for Cortex-M4/M3/M0 with little endian and big endian. Same header file will be used for floating point unit(FPU) variants.
-   * Define the appropriate pre processor MACRO ARM_MATH_CM4 or  ARM_MATH_CM3 or
-   * ARM_MATH_CM0 or ARM_MATH_CM0PLUS depending on the target processor in the application.
-   *
-   * <b>Examples</b>
-   *
-   * The library ships with a number of examples which demonstrate how to use the library functions.
-   *
-   * <b>Toolchain Support</b>
-   *
-   * The library has been developed and tested with MDK-ARM version 4.60.
-   * The library is being tested in GCC and IAR toolchains and updates on this activity will be made available shortly.
-   *
-   * <b>Building the Library</b>
-   *
-   * The library installer contains project files to re build libraries on MDK Tool chain in the <code>CMSIS\\DSP_Lib\\Source\\ARM</code> folder.
-   * - arm_cortexM0b_math.uvproj
-   * - arm_cortexM0l_math.uvproj
-   * - arm_cortexM3b_math.uvproj
-   * - arm_cortexM3l_math.uvproj
-   * - arm_cortexM4b_math.uvproj
-   * - arm_cortexM4l_math.uvproj
-   * - arm_cortexM4bf_math.uvproj
-   * - arm_cortexM4lf_math.uvproj
-   *
-   *
-   * The project can be built by opening the appropriate project in MDK-ARM 4.60 chain and defining the optional pre processor MACROs detailed above.
-   *
-   * <b>Pre-processor Macros</b>
-   *
-   * Each library project have differant pre-processor macros.
-   *
-   * - UNALIGNED_SUPPORT_DISABLE:
-   *
-   * Define macro UNALIGNED_SUPPORT_DISABLE, If the silicon does not support unaligned memory access
-   *
-   * - ARM_MATH_BIG_ENDIAN:
-   *
-   * Define macro ARM_MATH_BIG_ENDIAN to build the library for big endian targets. By default library builds for little endian targets.
-   *
-   * - ARM_MATH_MATRIX_CHECK:
-   *
-   * Define macro ARM_MATH_MATRIX_CHECK for checking on the input and output sizes of matrices
-   *
-   * - ARM_MATH_ROUNDING:
-   *
-   * Define macro ARM_MATH_ROUNDING for rounding on support functions
-   *
-   * - ARM_MATH_CMx:
-   *
-   * Define macro ARM_MATH_CM4 for building the library on Cortex-M4 target, ARM_MATH_CM3 for building library on Cortex-M3 target
-   * and ARM_MATH_CM0 for building library on cortex-M0 target, ARM_MATH_CM0PLUS for building library on cortex-M0+ target.
-   *
-   * - __FPU_PRESENT:
-   *
-   * Initialize macro __FPU_PRESENT = 1 when building on FPU supported Targets. Enable this macro for M4bf and M4lf libraries
-   *

-/**
- * @defgroup groupFastMath Fast Math Functions
- * This set of functions provides a fast approximation to sine, cosine, and square root.
- * As compared to most of the other functions in the CMSIS math library, the fast math functions

- * This set of functions operates on complex data vectors.
- * The data in the complex arrays is stored in an interleaved fashion
- * (real, imag, real, imag, ...).
- * In the API functions, the number of samples in a complex array refers
- * to the number of complex values; the array contains twice this number of
- * real values.

-
-/**
- * @defgroup groupFilters Filtering Functions
- */
-
-/**
- * @defgroup groupMatrix Matrix Functions
- *
- * This set of functions provides basic matrix math operations.
- * The functions operate on matrix data structures.  For example,
- * the type
- * definition for the floating-point matrix structure is shown
- * below:
- * <pre>
- *     typedef struct
- *     {
- *       uint16_t numRows;     // number of rows of the matrix.
- *       uint16_t numCols;     // number of columns of the matrix.
- *       float32_t *pData;     // points to the data of the matrix.
- *     } arm_matrix_instance_f32;
- * </pre>
- * There are similar definitions for Q15 and Q31 data types.
- *
- * The structure specifies the size of the matrix and then points to
- * an array of data.  The array is of size <code>numRows X numCols</code>
- * and the values are arranged in row order.  That is, the
- * matrix element (i, j) is stored at:
- * <pre>
- *     pData[i*numCols + j]
- * </pre>
- *
- * \par Init Functions
- * There is an associated initialization function for each type of matrix
- * data structure.
- * The initialization function sets the values of the internal structure fields.
- * Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
- * and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types,  respectively.
- *
- * \par
- * Use of the initialization function is optional. However, if initialization function is used
- * then the instance structure cannot be placed into a const data section.
- * To place the instance structure in a const data
- * section, manually initialize the data structure.  For example:
- * <pre>
- * <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
- * <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
- * <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
- * </pre>
- * where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
- * specifies the number of columns, and <code>pData</code> points to the
- * data array.
- *
- * \par Size Checking
- * By default all of the matrix functions perform size checking on the input and
- * output matrices.  For example, the matrix addition function verifies that the
- * two input matrices and the output matrix all have the same number of rows and
- * columns.  If the size check fails the functions return:
- * <pre>
- *     ARM_MATH_SIZE_MISMATCH
- * </pre>
- * Otherwise the functions return
- * <pre>
- *     ARM_MATH_SUCCESS
- * </pre>
- * There is some overhead associated with this matrix size checking.
- * The matrix size checking is enabled via the \#define
- * <pre>
- *     ARM_MATH_MATRIX_CHECK
- * </pre>
- * within the library project settings.  By default this macro is defined
- * and size checking is enabled.  By changing the project settings and
- * undefining this macro size checking is eliminated and the functions
- * run a bit faster.  With size checking disabled the functions always
- * return <code>ARM_MATH_SUCCESS</code>.

-   * @defgroup PID PID Motor Control
-   *
-   * A Proportional Integral Derivative (PID) controller is a generic feedback control
-   * loop mechanism widely used in industrial control systems.
-   * A PID controller is the most commonly used type of feedback controller.
-   *
-   * This set of functions implements (PID) controllers
-   * for Q15, Q31, and floating-point data types.  The functions operate on a single sample
-   * of data and each call to the function returns a single processed value.
-   * <code>S</code> points to an instance of the PID control data structure.  <code>in</code>
-   * is the input sample value. The functions return the output value.
-   *
-   * \par Algorithm:
-   * <pre>
-   *    y[n] = y[n-1] + A0 * x[n] + A1 * x[n-1] + A2 * x[n-2]
-   *    A0 = Kp + Ki + Kd
-   *    A1 = (-Kp ) - (2 * Kd )
-   *    A2 = Kd  </pre>
-   *
-   * \par
-   * where \c Kp is proportional constant, \c Ki is Integral constant and \c Kd is Derivative constant
-   *
-   * \par
-   * \image html PID.gif "Proportional Integral Derivative Controller"
-   *
-   * \par
-   * The PID controller calculates an "error" value as the difference between
-   * the measured output and the reference input.
-   * The controller attempts to minimize the error by adjusting the process control inputs.
-   * The proportional value determines the reaction to the current error,
-   * the integral value determines the reaction based on the sum of recent errors,
-   * and the derivative value determines the reaction based on the rate at which the error has been changing.
-   *
-   * \par Instance Structure
-   * The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
-   * A separate instance structure must be defined for each PID Controller.
-   * There are separate instance structure declarations for each of the 3 supported data types.
-   *
-   * \par Reset Functions
-   * There is also an associated reset function for each data type which clears the state array.
-   *
-   * \par Initialization Functions
-   * There is also an associated initialization function for each data type.
-   * The initialization function performs the following operations:
-   * - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
-   * - Zeros out the values in the state buffer.
-   *
-   * \par
-   * Instance structure cannot be placed into a const data section and it is recommended to use the initialization function.
-   *
-   * \par Fixed-Point Behavior
-   * Care must be taken when using the fixed-point versions of the PID Controller functions.
-   * In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.
-   * Refer to the function specific documentation below for usage guidelines.

-   * @defgroup BilinearInterpolate Bilinear Interpolation
-   *
-   * Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
-   * The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
-   * determines values between the grid points.
-   * Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
-   * Bilinear interpolation is often used in image processing to rescale images.
-   * The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
-   *
-   * <b>Algorithm</b>
-   * \par
-   * The instance structure used by the bilinear interpolation functions describes a two dimensional data table.
-   * For floating-point, the instance structure is defined as:
-   * <pre>
-   *   typedef struct
-   *   {
-   *     uint16_t numRows;
-   *     uint16_t numCols;
-   *     float32_t *pData;
-   * } arm_bilinear_interp_instance_f32;
-   * </pre>
-   *
-   * \par
-   * where <code>numRows</code> specifies the number of rows in the table;
-   * <code>numCols</code> specifies the number of columns in the table;
-   * and <code>pData</code> points to an array of size <code>numRows*numCols</code> values.
-   * The data table <code>pTable</code> is organized in row order and the supplied data values fall on integer indexes.
-   * That is, table element (x,y) is located at <code>pTable[x + y*numCols]</code> where x and y are integers.
-   *
-   * \par
-   * Let <code>(x, y)</code> specify the desired interpolation point.  Then define:
-   * <pre>
-   *     XF = floor(x)
-   *     YF = floor(y)
-   * </pre>
-   * \par
-   * The interpolated output point is computed as:
-   * <pre>
-   *  f(x, y) = f(XF, YF) * (1-(x-XF)) * (1-(y-YF))
-   *           + f(XF+1, YF) * (x-XF)*(1-(y-YF))
-   *           + f(XF, YF+1) * (1-(x-XF))*(y-YF)
-   *           + f(XF+1, YF+1) * (x-XF)*(y-YF)
-   * </pre>
-   * Note that the coordinates (x, y) contain integer and fractional components.
-   * The integer components specify which portion of the table to use while the
-   * fractional components control the interpolation processor.
-   *
-   * \par
-   * if (x,y) are outside of the table boundary, Bilinear interpolation returns zero output.
