Despite the superiority of PBP and Mecanique IDE, working with the i2c commands is a bear! Struggled for a week on it, still no go. Went back to Arduino, and still cursing at all the syntax. However, a quick hookup and I have 80 LEDS spread across 5 boards (PCB above), running all kinds of patterns in COLOR without issue. It's basically the code I submitted (for Arduino) except the CS.digitalWrite is repeated 5 times, once for each board. I've got 20 pages of code done in Arduino, couldn't get one light to light up consistently with PBP.

Thanks anyway. Going to the Arduino forum now to find out how to create functions (subroutines) to make my code trim and proper.
