I have 12 5940's driving 64 rgb led's all ran by an Arduino Uno.. The colors are ordered blue, green and red. When I pulse the blue and green it works fine. When I pulse the red, I get flickering from the other colors on the last six chips, and on the entire ring every n'th(didn't count them) doesn't light and shifts forward on the update. Sounds like a timing issue to me. Any thoughts? Thanks.
