Having fun trying to get this panel running! While it does display something close to a moving cube using D0, it’s obviously not right. Had high hopes for panel type FM6126A, but no joy. Any suggestions?
(Edit: Sorry - fixed product link)
Oh, and I should say this is being driven by a Pi 3B with an Adafruit RGB Matrix HAT and I have also tried all the multiplex options.
There are several threads (here and elsewhere) with discussions about how to work with this type panel. Unfortunately I haven’t found a definitive solution. I am making progress though.
sudo ./demo -D0 --led-rows=64 --led-cols=128 --led-gpio-mapping=adafruit-hat --led-chain=1 --led-show-refresh --led-parallel=1 --led-pwm-dither-bits=1 --led-pwm-bits=7 --led-row-addr-type=0 --led-panel-type=FM6126A
Hi, try ledrowadresstype 3
Thank you! Unfortunately the panel stays completely black with that option.
Looks like @alsaleem00 has created a driver that will work. Am hoping it can be merged with the code base.
I believe you have this panel Sigh, new panels: ABC with fm6126A (128x64) · Issue #823 · hzeller/rpi-rgb-led-matrix · GitHub
Try: ~/rpi-rgb-led-matrix/examples-api-use/demo --led-rows=64 --led-cols=128 --led-chain=1 --led-show-refresh --led-parallel=3 --led-pwm-dither-bits=1 --led-pwm-bits=7 --led-panel-type=FM6126A --led-row-addr-type=3
Wow. Was almost certain I had tried that config, but this time it was much better. Just a couple of changes - I only have a single panel and an Adafruit HAT, so I added --led-gpio-mapping=adafruit-hat and changed the --led-parallel=1, Now just need to track down a phantom row of leds at the bottom of the panel!
