  33  *
  34  *  This file is the master dispatch header file for the board-specific LED driver, for boards containing user
  35  *  controllable LEDs.
  36  *
  37  *  User code should include this file, which will in turn include the correct LED driver header file for the
  38  *  currently selected board.
  39  *
  40  *  If the BOARD value is set to BOARD_USER, this will include the /Board/LEDs.h file in the user project
  41  *  directory.

  48  *  The following files must be built with any user project that uses this module:
  49  *    - None
  50  *
  51  *  \section Module Description
  52  *  Hardware LEDs driver. This provides an easy to use driver for the hardware LEDs present on many boards. It
  53  *  provides an interface to configure, test and change the status of all the board LEDs.
  54  *
  55  *  If the BOARD value is set to BOARD_USER, this will include the /Board/Dataflash.h file in the user project
  56  *  directory. Otherwise, it will include the appropriate built in board driver header file. If the BOARD value
  57  *  is set to BOARD_NONE, this driver is silently disabled.
  58  *
  59  *  \note To make code as compatible as possible, it is assumed that all boards carry a minimum of four LEDs. If
  60  *        a board contains less than four LEDs, the remaining LED masks are defined to 0 so as to have no effect.
  61  *        If other behavior is desired, either alias the remaining LED masks to existing LED masks via the -D
  62  *        switch in the project makefile, or alias them to nothing in the makefile to cause compilation errors when
  63  *        a non-existing LED is referenced in application code. Note that this means that it is possible to make
  64  *        compatible code for a board with no LEDs by making a board LED driver (see \ref Page_WritingBoardDrivers)
  65  *        which contains only stub functions and defines no LEDs.
