  32  *  \brief Master include file for the board LEDs driver.
  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.
  42  *
  43  *  For possible BOARD makefile values, see \ref Group_BoardTypes.

  49  *  \section Sec_Dependencies Module Source Dependencies
  50  *  The following files must be built with any user project that uses this module:
  51  *    - None
  52  *
  53  *  \section Sec_ModDescription Module Description
  54  *  Hardware LEDs driver. This provides an easy to use driver for the hardware LEDs present on many boards. It
  55  *  provides an interface to configure, test and change the status of all the board LEDs.
  56  *
  57  *  If the BOARD value is set to BOARD_USER, this will include the /Board/Dataflash.h file in the user project
  58  *  directory. Otherwise, it will include the appropriate built in board driver header file. If the BOARD value
  59  *  is set to BOARD_NONE, this driver is silently disabled.
  60  *
  61  *  For possible BOARD makefile values, see \ref Group_BoardTypes.
  62  *
  63  *  \note To make code as compatible as possible, it is assumed that all boards carry a minimum of four LEDs. If
  64  *        a board contains less than four LEDs, the remaining LED masks are defined to 0 so as to have no effect.
  65  *        If other behaviour is desired, either alias the remaining LED masks to existing LED masks via the -D
  66  *        switch in the project makefile, or alias them to nothing in the makefile to cause compilation errors when
  67  *        a non-existing LED is referenced in application code. Note that this means that it is possible to make
  68  *        compatible code for a board with no LEDs by making a board LED driver (see \ref Page_WritingBoardDrivers)
  69  *        which contains only stub functions and defines no LEDs.
  70  *
  71  *  \section Sec_ExampleUsage Example Usage
  72  *  The following snippet is an example of how this module may be used within a typical
  73  *  application.
  74  *
  75  *  \code
  76  *      // Initialise the board LED driver before first use
  77  *      LEDs_Init();
  78  *
  79  *      // Turn on each of the four LEDs in turn
  80  *      LEDs_SetAllLEDs(LEDS_LED1);
  81  *      _delay_ms(500);
  82  *      LEDs_SetAllLEDs(LEDS_LED1);
  83  *      _delay_ms(500);
  84  *      LEDs_SetAllLEDs(LEDS_LED1);
  85  *      _delay_ms(500);
  86  *      LEDs_SetAllLEDs(LEDS_LED1);
  87  *      _delay_ms(500);
  88  *
  89  *      // Turn on all LEDs
  90  *      LEDs_SetAllLEDs(LEDS_ALL_LEDS);
  91  *      _delay_ms(1000);
  92  *
  93  *      // Turn on LED 1, turn off LED 2, leaving LEDs 3 and 4 in their current state
  94  *      LEDs_ChangeLEDs((LEDS_LED1 | LEDS_LED2), LEDS_LED1);
  95  *  \endcode
