first, install on Arduino IDE the library are you trying to use ... ESP32-HUB75-MatrixPanel-DMA. I suppose you already installed the ESP32 Board support, right? If not, do it first... google-search...

Greetings, You have only ONE unit of this panel? Have another one like 32x32? Also, change this: sudo examples-api-use/demo --led-rows=64 --led-cols=64 --led-parallel=1 --led-chain=1 --led-brightness=30 --led-rgb-sequence=RBG --led-limit-refresh=60 -D4 to sudo examples-api-use/demo...

ok add in Rpi4 the led-gpio-slowdown option now: sudo examples-api-use/demo --led-rows=64 --led-cols=64 --led-gpio-slowdown=4 -D4 test, between 2-4 (even 5) [read this](https://github.com/hzeller/rpi-rgb-led-matrix?tab=readme-ov-file#gpio-speed)

I will try tomorrow just as I do with a RPi 4

Greetings, You wanna be helped? First, take many pictures to your panel, specially to: HUB-75 LED INPUT, code of the RGB PANEL. Second, use the command : Command used on...

what power supply are You using?

FIRST, you need more knowledge about linux raspbian environment: use "ls" command to see the files (as dir in DOS) SECOND, the adafruit tutorial about how to testing LED panel,...
