Version 3.1.1 of library GxEPD is available, install with Library Manager.
- added support for GDEM029T94 2.9" b/w, actual Waveshare 2.9" b/w
- updated example GxEPD_WiFi_Example, for actual GitHub certificate
This panel has been reported to be used on the actual Waveshare 2.9" b/w board.
But I don't have this Waveshare board, so I can't check and test with.
