* User code should include this file, which will in turn include the correct LED driver header file for the
|
||||
* currently selected board.
|

*
|

* If the \c BOARD value is set to \c BOARD_USER, this will include the \c /Board/LEDs.h file in the user project
|
||||
* directory.

* For possible \c BOARD makefile values, see \ref Group_BoardTypes.

* The following files must be built with any user project that uses this module:
|
||||
* - None
|
||||
*
|
||||
* \section Sec_LEDs_ModDescription 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 \c BOARD value is set to \c BOARD_USER, this will include the \c /Board/LEDs.h file in the user project
|
||||
* directory. Otherwise, it will include the appropriate built-in board driver header file. If the BOARD value
|
||||
* is set to \c BOARD_NONE, this driver is silently disabled.
|
||||
*
|
||||
* For possible \c BOARD makefile values, see \ref Group_BoardTypes.
|
||||
*
|
||||
* \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 behavior 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.
|
||||
*
|
||||
* \section Sec_LEDs_ExampleUsage Example Usage
|
||||
* The following snippet is an example of how this module may be used within a typical
|
||||
* application.
|
||||
*
|
||||
* \code
|
||||
* // Initialize the board LED driver before first use
|
||||
* LEDs_Init();
|
||||
*
|
||||
* // Turn on each of the four LEDs in turn
|
||||
* LEDs_SetAllLEDs(LEDS_LED1);
|
||||
* Delay_MS(500);
|
||||
* LEDs_SetAllLEDs(LEDS_LED2);
|
||||
* Delay_MS(500);
|
||||
* LEDs_SetAllLEDs(LEDS_LED3);
|
||||
* Delay_MS(500);
|
||||
* LEDs_SetAllLEDs(LEDS_LED4);
|
||||
* Delay_MS(500);
|
||||
*
|
||||
* // Turn on all LEDs
|
||||
* LEDs_SetAllLEDs(LEDS_ALL_LEDS);
|
||||
* Delay_MS(1000);
|
||||
*
|
||||
* // Turn on LED 1, turn off LED 2, leaving LEDs 3 and 4 in their current state
|
||||
* LEDs_ChangeLEDs((LEDS_LED1 | LEDS_LED2), LEDS_LED1);
