DFR0472 32x32 LED Matrix with TC5020A shift-registers - What the hell?

Anyone successful getting these to work with Raspberry PI? I can get it to at least show scrambled results using rpi-rgb-led-matrix with:

 sudo ./examples-api-use/demo -D 0 --led-rows=32 --led-cols=32 --led-gpio-mapping=adafruit-hat-pwm --led-slowdown-gpio=2 --led-no-hardware-pulse

I think the problem is with the pinout or code/mappings in rpi-rgb-led-matrix and so I'm starting down a troubleshooting path here. DFRobot Advertises these with different LED drivers than advertised, so I wasted time there already. I don't even know if the product is defective or not. Quite annoying to have to reverse engineer this crap.

Any insights would be great.
