Overdue update: my AI agent got a modified fork of OpenEPaperLink running on a hacked e-paper price tag.
The tag has an EFR32FG22 and a 2.6" black/white/red panel. My part was just soldering the SWD wires and doing a few HW measurements. The agent did the rest: it flashed builds over SWD, read the RTT logs and fixed the display driver until the panel finally rendered.
The photo isn't mine. The agent took it itself with the webcam to see if it works.
