57
 *  Hardware LEDs driver. This provides an easy to use driver for the hardware LEDs present on many boards. It
 *  provides an interface to configure, test and change the status of all the board LEDs.
 *
58
 *  If the \c BOARD value is set to \c BOARD_USER, this will include the \c /Board/LEDs.h file in the user project
59
 *  directory. Otherwise, it will include the appropriate built in board driver header file. If the BOARD value
60
 *  is set to \c BOARD_NONE, this driver is silently disabled.
61
 *
62
 *  For possible \c BOARD makefile values, see \ref Group_BoardTypes.
63
 *
64
65
 *  \note To make code as compatible as possible, it is assumed that all boards carry a minimum of four LEDs. If
 *        a board contains less than four LEDs, the remaining LED masks are defined to 0 so as to have no effect.
66
 *        If other behaviour is desired, either alias the remaining LED masks to existing LED masks via the -D
67
68
69
70
71
 *        switch in the project makefile, or alias them to nothing in the makefile to cause compilation errors when
 *        a non-existing LED is referenced in application code. Note that this means that it is possible to make
 *        compatible code for a board with no LEDs by making a board LED driver (see \ref Page_WritingBoardDrivers)
 *        which contains only stub functions and defines no LEDs.
