RGB LED Matrices With The STM32 and DMA

A few years ago, [Frans-Willem] bought a few RGB LED panels. Ten 32×16 panels is a lot of LEDs, and to drive all of these panels requires some sufficiently powerful hardware. He tried working with an FPGA development board, but that didn’t have enough memory for 24-bit color. The microcontroller du jour – a TI Stellaris – couldn’t get more than 16 bits of color without flickering. With a bunch of LEDs but no way to drive them, [Frans-Willem] put the panels in a box somewhere, waiting for the day they could be used to their fullest capacity. This day came when [Frans-Willem] was introduced to the STM32 series of chips with the F1 Discovery board. While looking for some electronic playthings to use with this board, he stumbled upon the LED panels and gave them one more try. The results are spectacular , with 33 bits of color, with animations streamed over a router over WiFi....
