I’m working on a controller board for the 16×32 and 32×32 RGB LED Matrix Displays you may have seen at Adafruit and Sparkfun.
After seeing Paul’s post on driving WS2811 LED strips with DMA on the Teensy 3.0, I looked into driving the Matrix displays with DMA and now have the basics of a driver working. The Arduino really struggles to drive these displays, but the Teensy 3.0 with DMA is able to update them at a high frame rate with CPU left over to do other stuff. I’m working on releasing an open source library for driving the displays, and want to release a open source breakout board as well.
