| * \section Purpose |
| * |
| * Small set of functions for simple and portable LED usage. |
| * |
| * \section 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, \ref 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. |
