Hi all,
anybody who has managed to compile for the Lilygo T547 e-paper and is willing to share?
I have tried various sources and all I got was a ton of errors:
Running HAOS core 2025.12.1 with ESPHome 2025.12.7
This is an example for a .yaml file, super simple “Hello World”-style. Getting different kinds of compiling errors. “Could not find package Wire”,

It is compiling, however I am getting this error in a loop on the device.

Oh, I have just found out that the git by hbast is for the t547 plus only, I have the “old classic” one. So that one won’t work
