Function Documentation

◆ main()

int main	(	int	argc,
		char **	argv
	)

The device has a RGB LED, which has two states for each "sub-LED", on and off. The "sub-LEDs" are red, green and blue.

Obviously there are 8 possible combinations for their state. It seems there aren't bits mapped to each sub-LED, but instead 3-bit values mapped to the 8 combinations.
