I'm having the hardest time getting multiple Arduinos to run 50 pixel strands. Each one works on it's own, and each one has it's own com port 6, 7, and 8. All are set up in Vixen as their respective 6, 7, and 8, with the settings all consistent, and all are receiving data from Vixen because I can see the receive led on each Arduino active. I know my hub works, because I can program each Arduino via the IDE, but they won't run the lights, and using a scope I don't see any data going out except on one. I'm really wanting to go with pixels this year, but only one limits me to about 300 pixels. I hope someone has been there and done that!
