\r
35 * Small set of functions for simple and portable LED usage.
\r
39 * -# Configure one or more LEDs using LED_Configure and
\r
41 * -# Set, clear and toggle LEDs using LED_Set, LED_Clear and
\r
44 * LEDs are numbered starting from 0; the number of LEDs depend on the
\r
45 * board being used. All the functions defined here will compile properly
\r
46 * regardless of whether the LED is defined or not; they will simply
\r
47 * return 0 when a LED which does not exist is given as an argument.
\r
48 * Also, these functions take into account how each LED is connected on to
\r
49 * board; thus, \ref LED_Set might change the level on the corresponding pin
\r
50 * to 0 or 1, but it will always light the LED on; same thing for the other
