We did something like this with lighting panels with 2 separate circuits
on each panel. The PICs were interconnected with CAN, with a local DIP
switch to set the address of each one. The PWM outputs were used to
drive the LEDs on the panels via a couple of MOSFETs. It was pretty nice
to do.
cheers, Rich.
