LED window display

Collecting notes for the LED window display.

Anyone have ideas for a better project name???

System Architecture

nCode

This is intended to be a common format that is read by the computer connected to the LED driver. The syntax is based on JSON. The pixels in the frames represent Red, Green, Blue, and Alpha values. It is assumed that 0,0 is in the upper left corner of the display.

^^ these turned out to be wrong, since we needed common anode.

Marty purchased 100 common anode ones so now we have those.
