This works fine on a single 8×8 but if I hook it up to a 4 block of 8×8 (32×8) then the rightmost 8×8 is fine, next in adds some LEDS, and the same for the remaining two 8X8’s. The random LED’s are always the same ones and I have tried swapping over the 8X8 blocks with the same results.
Do you think I have a faulty PCB/Max7219 chip(s), or is there additional code required to drive the 4 segments?
Love your channel, I’ve learned loads, thank you so much.

I connected it and it works just fine. However I have four of them connected. I can address only the first one. how do i work with 4 of them? Thank you!

It works fine.
I can send the code.

The problem seems to be with a newer version of the timer library. The older version you linked works fine though!

Used the first bit in an university engineering task (this site was referenced). Would have loved to include the pong game as well, but we were being marked on size of the program.

Really made my life a lot easier
