BLM 8x16 Project - DOUT LED Advice Needed

[Rowan]

I've built the DIN side of a 8x16 BLM and it's working great but I'm at a bit of a dead end on the DOUT side for the LED's.

 

What I'm looking for is a schematic for single colour LED's in a 8x8 matrix configuration for the MIDIO128 App.

 

Any advice?
