LED Matrix Serial Number Fix

Community Support

There seems to be no way to differentiate LED Matrix modules. I have 2 currently showing CPU usage but I want one side to show other things as well. There seems to be no way to reliable differentiate left and right. I am blaming this on the fact that the LED Matrix Module comes without a valid serial number. They are both:
FRAKDEBZ0100000000
So it seems they forgot to add any increment to the base number.

Question:
Is there a firmware update / way to change the firmware to change the serial number or otherwise differentiate a set of LED Matrix Modules?

If you are comfortable compiling and flashing your own firmware, you can probably just alter this line: inputmodule-rs/ledmatrix/src/main.rs at main · FrameworkComputer/inputmodule-rs · GitHub

If you are using Linux as your OS, you can differentiate the modules by using the devices entries inside of /dev/serial/by-path/ (rather than the direct entries in /dev), as those won’t change between reboots.

Thanks for the detailed reply. The readme on the firmware page seems easy to follow and I can start using /dev/serial/by-path right away.
