+For the LED Matrix we wanted to build on the [[CCCamp2007]] we decided to design a GNU LEDMatrix Controller/Driver setup. It consists of two parts the FPGA board and a several driver electronics boards. Now almost one year later we're finally done!

-x48 = 3456 bytes of pixeldata ranging from 0 (0x00) to 15 (0x0F)
- each byte represets one pixel with a brightness ranging from 0 to 15
+=== Raw protocol ===
- the pixels start at the upper left corner and are numbered as in the selfexplaining example below.
- All output on is doublebuffered on the fpga so you have to send a 0x80 after the pixeldata to flip
+x48 = 3456 octets of pixel data followed by a terminating 0x80 octet.
- the framebuffers.
+Each pixel data octet represents one pixel's brightness, ranging from 0 (0x00, off) to 15 (0x0F, brightest).
+The pixels start at the upper left corner and are numbered in [http://en.wikipedia.org/wiki/Row-major_order row-major order] (see the diagram below).
+All output is double-buffered on the fpga, so you have to send a 0x80 after the pixel data to flip the frame buffers.
