| /// !Purpose | |
| /// | |
| /// Small set of functions for simple and portable LED usage. | |
| /// | |
| /// !Usage | |
| /// | |
| /// -# Configure one or more LEDs using LED_Configure and | |
| /// LED_ConfigureAll. | |
| /// -# Set, clear and toggle LEDs using LED_Set, LED_Clear and | |
| /// LED_Toggle. | |
| /// | |
| /// LEDs are numbered starting from 0; the number of LEDs depend on the | |
| /// board being used. All the functions defined here will compile properly | |
| /// regardless of whether the LED is defined or not; they will simply | |
| /// return 0 when a LED which does not exist is given as an argument. | |
| /// Also, these functions take into account how each LED is connected on to | |
| /// board; thus, <LED_Set> might change the level on the corresponding pin | |
| /// to 0 or 1, but it will always light the LED on; same thing for the other | |
| /// methods. | |
