* \section Module Description
|
|
* 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.
|
|
*
|
|
* If the BOARD value is set to BOARD_USER, this will include the /Board/Dataflash.h file in the user project
|
|
* directory. Otherwise, it will include the appropriate built in board driver header file.
|
|
*
|
|
* \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.
|
|
* If other behaviour is desired, either alias the remaining LED masks to existing LED masks via the -D
|
|
* 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.
