See #334 and #335 for more details.

In short, waveshare introduced a bug in the driver for the 12.48" display to add support for Raspberry Pi 5, but this caused non-Raspberry-Pi-5 rendering attempts with the 12.48" to fail. Furthermore, this PR will allow using the latest version of Raspberry Pi OS again and will hopefully also work with the latest kernel introduced in this version.

The changes boil down to the following:

  • Downgrading epdconfig (known as epdconfig_12_in_48.py in Inkycal) to a version that has been confirmed to work
  • Installing wiringpi from GitHub
  • Updating Raspberry Pi OS image used by tests to the latest version (15th March 2024)
  • Removing warning about the latest OS from the README (breaking change due to kernel upgrade)

Special thanks to @J-CMartin for finding the issue, performing the tests and providing useful information on how to fix this

See #334 and #335 for more details

Changes look good. One minor fix to ReadMe is needed.
