OK, I have a conundrum. I have a bunch of LDP6803 based LED pixels and want to build an adavision type thing or at least a large matrix of 20X20. I got the Adafruit library for them up and running on a boarduino this afternoon, but not the 324u breakout board. What I am wondering is how to even tackle a processing library for them or if anyone knows how to adapt the WS2801 library to it. I am suspecting that the big difference is the resolution of 15 bits for the LDP6803 vs 3 bytes for each WS2801. Any pointers on where to start? I am persistent but not a programming guru by any stretch of the imagination.
