I cant seem to get the RGBmtx to work... For some reason it is stuck in plasma mode possibly? I am not sure. I see the RXTX lines working, but nothing changes on the display. Am I doing something wrong?
This is great, I'm looking at doing something similar with a Colorduino but I'm thinking of using 2 RGB LEDs per cell. I cant work out from the datasheet, would the Colorduino be able to power that? It says 60ma per channel, does that mean it can only power 1 LED (since RGB use 20ma for each leg x 3 = 60ma) or does it mean it can power 3 RGB leds?
the colorduino only has enough RAM to hold a few frames at a time. If you store the animation in program memory, however, and send it over as part of the sketch, it can hold a lot more. I'm eventually going to add an SD card so that it has more dynamic storage.
@lincomatic alright, sweet. I hope to see it added to your instructable sometime. really interested in using it standalone, but I'm not exactly a pro at Arduino yet..

@jimbom2k I seem to remember reading the specs and concluding that 2 LED/s channel was too much current, but you can just email ITead to verify

can you upload an animation to the board and then run it standalone without being connected to a computer?

@lorenznijs no, the board doesn't have enough memory. but it can be done by adding an SD card interface

sorry, i can't remember ... it's from the moods collection in youtube's audioswap function. i just spent 15 min looking for it and can't find it.
