single panel 64x64

[JeremC82]

Hello, I am facing a problem.
I wrote a code which depending on the activation of a strap configures the mcu for two 64x32 panels or a single 64x64 panel. It works perfectly on the two 64x32 panels. On the other hand, on the 64X64 model I have a big offset. However, I declared and connected my io 32 pin

Can you post a video of the issue?

Looks like some interference to me. Make you are not using GPIOs that are used for serial communications, also, make sure the wire running from the esp32 to panel is not longer than 10cm
