This is the 3rd test of my RGB LED Matrix. I now have all 3 sets of coloured LED's (Red, Green and Blue) connected and therefore all 192 LED's connected up to my micro controller (An Arduino). The only thing between the Arduino and the Matrix are 4 x 74HC595N 8-bit serial-parallel Shift Registers. Each register controls a seperate bank of colours with the final register multiplexing the common anode rows. The use of the shift registers plus the technique of multiplexing means I only need 3 digital outputs from my micro controller instead of 192.

Code on the micro controller is scrolling my test message demonstrating each of the 7 colours (blue, green, light blue, red, purple, yellow & white) in turn.

Next step is to tidy up the appearance of the font and to write functions to set individual dots, draw lines, boxes, cycle through preset animations, etc. I've also order some 64k EEPROM's to store the font array and animations in.

I have purposely decreased the exposure in the video to bring out the colours.

    How did you write the code for this? im trying to do pretty much teh same thing, but im trying to use an existing library and just editing it. Could you post a link?
