Hello everyone, I have recently purchased one of those cool RGB matrix controllers from Sparkfun, and am just beginning to full understand how to work it . Because of it's onboard SPI functionality, I figured I'd control it with that. I only have 2 uC's with SPI capablity (16F88 and ATtiny13) and hopefully will use the PIC, for which I have better programming equipment. However, is this possible to have a PIC control an AVR via SPI? Also, if any of you have any sample code/schematics or links they would be very much appreciated, as I'm just a highschool student introducing myself to this new hobby.
