Unwanted lit pixels across top of display (photos attached)

[877cms]

All working well with esp32, except for there are pixels lit up across the 1st row of the display which seem to correspond to where the numbers 'fall' from.

Code used here https://pastebin.com/7hbYMFpw I've also tried AlphaTest example and it's the same.

Problem - see top row:

Hi @877cms,

I didn't see this issue before. I hope to revisit this project again soon as I find time and I'll try that out on my new 64x32 matrix I've lying around here.

The schematic looks OK to me. And that it's happening with another example code makes me think of a hardware or library problem.

If it's happening with the examples from https://github.com/2dom/PxMatrix/ maybe someone over there can help?

Best regards Tobas

Hi @toblum

Many thanks for the reply, it's working fine with a static image (Mario) so I think it may be a library issue or a code issue. I will post over on PxMatrix to check I have it set up properly.

Have fun with your 64x32 matrix!

Thanks 877dev
