My Google-fu has completely failed me. I've got an RGB addressable led curtain. It has 20 strings of 20 LEDs in a square arrangement. I initially assumed it had a wire feeding led data back up, to go to the next drop. On checking however, they are T jointed.

Apparently the address is hard coded into the RGB controller in the LED. I've found a few places where others have talked about them. I've also found that adafruit had some available,, unfortunately they lacked any info on how they are programmed, or where to source them from.

Anyone got any info on what the chip name of these is? Even better if you have any info on how they are programmed etc!
