* @brief Access macros to control the on-board LEDs
*
* This header contains a set of macros for controlling the on-board LEDs of
* a board. The LEDs are enumerated, starting from LED0 to LED7. As most
* platforms have a different number of LEDs, the existing ones are mapped onto
* the lowest LED numbers, while the higher LED numbers will simply be empty
* defines. This ensures, that the LED macros are portable to any platform with
* any number of LEDs.
*
* Providing access macros to 8 LEDs is a random decision, as currently 8 is the
* maximum number of on-board LEDs found on any board in RIOT (stm32f3discovery).
