I'm using a Arduino Uno for power and transfer, and a Rainbowduino v2 with a 8x8 Matrix
When I upload the Rainbowduino_v3_0h firmware the board lights up in the standard diagonal rainbow (See picture)
But if I try to upload anything else, even the most basic sketch, it will go "upload done" with no errors, but no lights will appear.
Anyone know what I'm doing wrong here?
