Had a similar experience. I bought an ePaper display and a Pi 4 to run a calendar widget on. I got stuck because the open source project I was building off expected the previous generation of ePaper display, and the firmware had changed completely. I found the new firmware examples, but got stuck trying to get it to work. With Claude assisting we banged it out in two sessions of about 3 hours each.

codeberg.org/mjmvisser/infoframe if anyone’s interested.
