well... so far I have a rough plan on how I can implement this "rainbow FoC" feature. for non electronics experts this may be over your head, and for that I am sorry.
I plan on building a circuit that consists of a 555 timer in astable mode to as a clock pulse for a binary counter. 3 of the outputs for the counter control the RBG LEDs . To activate this circuit I am hoping to have one of the accent LED pads set to turn on and stay on for the duration of the FoC feature. Also, in order to prevent both the PC3 and this circuit from sending signals to the LEDs at the same time, I am planning on setting the PC3 to have absolutely no output to the LEDs for the duration of the FoC feature.
for those who understood this and has more experience with the plecter products, does this sound like a decent solution? if not, what would you do different?
thanks!
