LED Matrix Modules

Framework Laptop 16
1

I have the LED Matrix modules but am struggling to get them to work. I’ve downloaded a project from github but I can’t get it to work. The python script that is I think official is really bad. I don’t know exactly what I want to do with them, but it would be nice to at least have them on! Thanks

I tried this one: GitHub - FrameworkComputer/inputmodule-rs: Framework Laptop 16 Input Module SW/FW

I’ve been using this to make use of my Matrix modules. I rather like the at-a-glance for my system status.

It’s all written in python, so you can tweak and modify it as you see fit. It’s also robust enough that, with it running as a system service all the time, you can remove and reinstall the modules whenever (I sometimes swap in my numpad when working) and they begin reporting again properly right away.

A script to display battery percentage, quick and dirty:
