did you work out how to fix this? i have the same issue
No, I had to rewrite my software and remap pixel addressing
These things can be simplified by using the library's PixelMapper feature - you can write a class that will tell how input to output pixels map, register it with the library and enable, and your application then does not have to worry about that anymore as it writes its images to the canvas which does the mapping to the right location on the panel automatically.
There are a few standard mappers defined that you can access directly at the command-line, e.g. things that rotate or mirror the image or accomodate certain panel wirings. But with the PixelMapper, the library gives you the liberty to define a special mapping needed in your project.
Hi, guys. I've connected chain of two led panes (40x20) with the Amperka driver to the my Rpi4. All works but I cannot change the order of panels. pixel-mover shows X,Y = 0,0 on the second (right) pane not on the left.
sudo ./rpi-rgb-led-matrix/examples-api-use/pixel-mover --led-rows=20 --led-cols=40 --led-multiplexing=16 --led-gpio-mapping=adafruit-hat --led-chain=2
