After some fussing we found Trammell Hudson's really excellent Octoscroller and LEDscape project to interface with our low-level hardware.
We also need an Octoscroller cape. You can order the cape circuit board in sets of 3 from OSH Park! Share with a friend! The process takes two or three weeks.
Make a DigiKey order. Here are the parts you want:
|1||296-8503-5-ND||8-bit bus transceiver|
|8||S9171-ND||16 pin ribbon connector|
|4||S1012E-36-ND||Breakable header pins|
Solder your hardware. The buffer IC goes on the underside of the circuit board. Solder this first. The hole in the ribbon cable connectors face towards the bottom of the PCB.
These LED panels can potentially use a lot of power. Make sure you have an adequate power supply (~1.5A panel) or you may experience unusual issues!
