1 - 8x8 Common Anode RGB matrix
4 - 74hc595 shift registers.
According to the following schematic each chip is responsible for one color and 1 chip for the anodes..
What dictates what chip will handle which color? And what dictates which one will be the chip serving the anodes?
I have built the following schematic on a breadboard, when I was done the colors and the anodes were wrong.
A little testing and I was able to figure out what chip = what color and what the anodes were.
Rewired, the breadboard circuit worked perfect.
Before I build this onto a pcb and solder it, I want to make sure I have the correct layout correct
