I’m struggling to get any reasonable output trying to run demo 0 (rotating square). I had claude create a script that cycles through hundreds of configuration options but at the end of the day the closest I get is garbled lights. I’m running a raspberry pi 4 B with an [ElectroDragon RGB Matrix Panel Drive Board](https://www.electrodragon.com/product/rgb-matrix-panel-drive-board-for-raspberry-pi-v2/).

I purchased [these boards](https://www.aliexpress.us/item/3256809767134266.html?spm=a2g0o.order_list.order_list_main.5.41d21802ClHV9H&gatewayAdapt=glo2usa) from AliExpress (B44C 3Pcs P6 Outdoor LED Screen Panel 32X32 Pixels LED Display Module 192X192mm 1/4 Scan RGB Full Color LED Screen Panel).

The Hub75 pins are labeled as labeled as.  
R1 - G1  
B1 - GND  
R2 - G2  
B2 - GND  
A - B  
C - NC  
CLK - LAT  
OE - GND

I do have a spare P3 64x64 panel I used for verifying my setup and I could get that panel to work just fine. But the P6 32x32 has been a no go. Please help!

The most probably reason of this that the panels are “1/4 Scan”. Such panels needs to setup a custom pixel mapping as described in Readme “Multiplexing” section:
