Using --led-slowdown-gpio=2 as argument doesnt work #37

My setup (3x2, 192X64) works, but has quite some jitter. Using hzeller implementation, I can fix this issue with using --led-slowdown-gpio=2. Also tried to fix it in node-red by adding --led-slowdown-gpio=2 to the "Command-Line Arguments" field but it seems it doesnt affect anything.

same here. any solution for that. maybe a workaround?

If you also need a solution, quick an dirty would be to edit: /root/.node-red/node_modules/easybotics-rpi-rgb-led-matrix/external/matrix/include/gpio.h and change line 40 slowdown = 1 to slowdown = 2

after that go to "/root/.node-red/node_modules" and do "npm rebuild"

not nice, but working

@mark77-DE is there a way to do the same with the other flags? I was looking to do the pixel mapper

@abwilson2020 I'm not an expert (was more luck, I did find the solution) but maybe if you specify, what you are looking fore, I can help.
