Using a Mkr 1310 to controll a 32x64 rgb Matrix

[simonji]

Hello,

at the moment i am trying to controll a 64X32 RGB Matrix (P4-2121) with an Arduino Mkr WAN 1310.
Sadly in found no matching wiring and library.

Instead I have taken the wiring from an example (Uno Version): https://learn.adafruit.com/32x16-32x32- ... mper-wires.
The programm i am using is an example from the "RGB matrix Panel" Library.

When I turned everything one nothing worked.
While powered on, only a current of 80mA is floating (limitation is at 4A).

Is there matching library for the MKR WAN 1310?
Is it possible edit my currently library to make it work?

// Pin 8 works on the Adafruit Metro M0 or Arduino Zero,
// Pin A4 works on the Adafruit Metro M4 (if using the Adafruit RGB
// Matrix Shield, cut trace between CLK pads and run a wire to A4).
