## Led Controller Code ## Led Controller Code
In the Infinity60 project folder, led_controller.c sets up ability to write led layers at startup or control leds on demand as part of fn_actions. By default led_controller.c assumes page 0 will be used for full on/off and page 7 for controlling individual leds. The remaining 6 pages (1-6) are free to preset led maps at init or on demand.
