The communcation with the game play controller is implemented as a sequences of tuples of LED address (0 to 211) and color code. A single octet of 253 where the LED address is expected is taken as the end-of-telegram mark. Readiness to receive a telegram is signaled to the game play controller via a single line connected to a GPIO of the game play controller.
