Bob Davis has been working on an 8×8 RGB LED array with a Raspberry Pi project:
I have been working on a book of Raspberry Pi projects. One of the projects is an 8×8 three color LED array. I picked up some more of them on eBay lately and they had a different pin-out.
The MEU 8860 RGB pin-out as seen from above. I use Dx for the rows as Rx is used for Red.
Check out the video after the break.
