Using SmartMatrix library with HUB12 monochrome panels

[Louis]

It’s a HUB12 (not HUB75) pinout. You can search Google Images for what a HUB12 pinout looks like.

I added limited support for HUB12 panels, with some brief info here:

SmartMatrix with 1/4 scan hub75 panels

Thanks to a generous donation from Martin Welford (@viking), I’m happy to say that the teensylc branch now has support for panels with non-linear pixel mapping, including multi-row-mapping, like the 1/4 scan panels mentioned above. I added this support to both the ESP32 and Teensy on that branch. Adding support for new panels requires some code changes, but it’s mostly copy/paste and modifying numbers, not actual coding from scratch, so it’s accessible to more people. There’s documentation in…

Some more details are in the ESP32 branch README:
