Can an RGB Matrix Hat or Bonnet create a 64x64 matrix from 2 64x32 matrixes?

Post by bdhoff »

I want to build a small-ish LED display so I bought 2 of these 64x32 matrixes:

To make this project:

https://learn.adafruit.com/raspberry-pi ... ix-display

I would have purchased a single 64x64 matrix but there aren't any I could find in a 6mm pitch. I have both a matrix hat and a matrix bonnet and they appear to work identically and perfectly.

I didn't know when I bought the materials for this that the project does not support Raspberry Pi 3B+, as the rpi-fb-matrix project is no longer supported and will not start to capture video output. Since the code won't execute I decided to use the rpi-rgb-led-matrix library, but I see no options to lay out two 64x32 matrixes as a 64x64 like rpi-fb-matrix does.

I have no issues running these chained as a 128x32 matrix. But I can't seem to get them to work in a 64x64 configuration. Has anyone been able to get this to work? If so, how? I've been looking at the code for rpi-rgb-led-matrix and it looks like it is coded to work if the matrixes are driven in parallel and not chained in series, but I'm not sure if that's right. I see no options for matrix layout at all. I searched the forum to see if anyone had already answered this question but so far haven't found anything to help. Any help would be appreciated.

Thanks!
