| Title: LED | |
| About: Purpose | |
| Small set of functions for simple and portable LED usage. | |
| About: Usage | |
| 1 - Configure one or more LEDs using <LED_Configure> and | |
| <LED_ConfigureAll>. | |
| 2 - Set, clear and toggle LEDs using <LED_Set>, <LED_Clear> and | |
| <LED_Toggle>. | |
| 3 - Get the current status of a LED using <LED_Get>. | |
| 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. | |
