Hi, I have one of the QiangLi P8 panels @JiDudeS suggested in his pull https://github.com/hzeller/rpi-rgb-led-matrix/pull/879 . I tried so much things, but can't get it to work. I'm using the active-3 board.

This is my command line string: sudo ./demo -D0 --led-rows=20 --led-cols=40 --led-multiplexing=10 --led-gpio-mapping=regular

I also tried all scan-modes and row-addr-types. No readable result. Anybody here who got the panel to run (maybe @JiDudeS)?

Any hints whatelse I could try? thanks!

solved the problem. it was the missing --led-slowdown-gpio statement.
