Meduim 32x32 RGB matrix "Draw" problems

Post by steveng »

I have checked the wiring to and from my Arduino UNO to the matrix carefully three times. I have not edited any of your code before noticing all of the 32x32 examples have drawing abnormalities. I've documented the problems below.

Could you post clear pictures of your board and the connections to it? Thanks.

Looks like a couple of the row select pins are out of place. Try swapping A1 and A2, see if that improves.

PBurgess,

You are correct, swapping those rows fixed the frustrating problem.
I'm impressed.

Thank you very much, now I can move forward!
