I was wondering if it is possible to address an 8x8 matrix alone.
What I am hoping to do: (5) 7219 chips side by side, scrolling a message. Then have (2) 7219 chips displaying random data. These 7219's will be connected to 8x8 LED matrices.
I can place the extra (2) either at the front or end of the chain, that won't be an issue.
