China RGB-LED-Matrix Display

Use cheap chines LED RGB modules to control the PWM of each individual LED by a CortexM4. Normally a FPGA is required for this work load. But you could also use the CortexM external parallel memory interface to get fast refresh rates. The Tiva-C boards from TI acts as WS2801 protocol receiver, so each WS2801 controller could be used. To Tiva boards could be chained. This gives controll over 2048 RGB-LEDs.
