Hi all! I need to connect two adafruit matrixes 64x32 64x32 RGB LED Matrix - 3mm pitch : ID 2279 : $44.95 : Adafruit Industries, Unique & fun DIY electronics and kits to BlinkStick Pro. Does anyone know how to do wiring? Many thanks for the help!
I think this might help 
I checked it. I used “mode 0” for rgb mode since led matrix has these pins: Connections | 32x16 and 32x32 RGB LED Matrix | Adafruit Learning System
But still doesn’t work
