Actually I didn't find that cuz generally I skip over any result that doesn't look like an actual datasheet will be there. But upon following your link and reading several threads, I have come to realize there is no available datasheet for this chip - at least not in english. So it looks like there are 2 choices - port the duino code to PBP, or play guessing games with the part. Assuming it has 4 connections, I would assume that it is an I2C interface.

If this is the case (which you may be able to verify by pouring over the duino code to find the actual method called to talk to it), you can just set up some loops to start sending address/data to see if anything happens. My guess would be an address for each chip maybe then some data describing the color. So I would start by sending FFh to all 127 address's 1 at a time then see if the LED's light up. If none do, try different data going through the entire address selection again.

Not sure if this is helpful or not, I hope it is. Also I hope I don't come off sounding like a smart A$$ - I do not mean too if I do.
