64x64 panel, every pair of lines are blank

[Tenumen]

Hi there
Would someone be able to point me to what is wrong with my setup and causing this issue where two lines are working then the next two are blank?

I am using an unnamed panel with E but no D channel. I obtained this pattern by running the Plasma Pattern example with only the pin-outs changed. I am using an ESP32-WROOM Dev board connected directly to the panel via a simple breadboard -so I am sending 3.3v signals to the panel.

Any guidance that someone can offer me would be much appreciated.
Thanks

This project is using a Raspberry Pi, not an ESP32.

Oops sorry! I've been looking at both yours and https://github.com/mrcodetastic/ESP32-HUB75-MatrixPanel-DMA and got the two mixed up.
