That’s on beaglebone, but I assume it shouldn’t be too different from a Pi code-wise (both are running linux).
It would be interesting if rpi-rgb-panel ran on that although I assume their have their own lib (not sure which one?).
Does anyone know more about it?
I filed a bug to track this RFE/Placeholder: Support for 6 port board: Beaglebone Pocketcroller V2 · Issue #1733 · hzeller/rpi-rgb-led-matrix · GitHub and get more info from the other team on how their driver works
