To do this project I came up with, I first experimented on a breadboard and then created the PCBs with the features I wanted. Unfortunately, I made some youthful mistakes in hardware development... trivial but significant...
I redid the PCB designs but haven't ordered them from the service yet. For now, I've already spent enough money on a "gamble."
If you want, there are some kits that need fixing, so it would arrive with various jumpers soldered on the fly.
In any case, the eval version is fully functional like the final one, but it doesn't have all the peripherals enabled.

I don't want you to be my free testers.So.....you are wanting testers for a closed source hardware project
What's in it for the testers ?

part of the udev rule.I've just pushed the fix to the repository. This is exactly why community feedback is so important! Now everything should set up correctly with a simple copy-paste.

Thanks COFHAL! You're right, I found the typo in the README and demo files. I missed a curly bracket in theThanks, I had an error in the rules file, that's why that error appeared.
ENV{ID_MM_DEVICE_IGNORE}

Another error I found is in the io_decoder-keymap.cfg file. In the example, there are comments with #, and when LCN is run, errors appear. I deleted all the extra lines and only left the lines that assign keys to the inputs.
