Issues with MMM-Button

@schlomm the bookworm os requires some configuration for the gpio pins. I think you can do this w raspi-config
Edit: this is not correct, my mistake (Sam)

I am not the author. I just fixed the Postinstall process

@schlomm Did you try the fork on the module list?

@KristjanESPERANTO I set up a fresh MagicMirror instance and checked the https://github.com/MarcLandis/MMM-Buttons repository. As a result I get the same issue:

…Yesterday evening I tried to fix the issue of not beingable to control the MagicMirror using some buttons. Digged into the original module, asked help of ChatGPT, debugged some functions and as a result I have a running version for Bookworm.
I’ll try to put this in a Github Repo - will update this thread as soon as I did :)

@sdetweil You’ve said that I only need to change some settings in the rasp-config. Do you have any additional information what needs to be changed?

@schlomm There is a PR that seems to fix the issue: https://github.com/MarcLandis/MMM-Buttons/pull/11
