I still fail when trying to load and test a lib example.
The GXEPD2 is in the PIO Lib selection. I can install them too.
I can also add them to a new project.
The files also appear at .pio .libdesp.
I copied the content of “GxEPD_HelloWorld” into main.cpp.
But when compiling example “GxEPD_HelloWorld” always appears: xxxx.h not found.
Was mache ich falsch? 
We need the full details: platformio.ini, link to the example code you’re trying to run, full error message.

// if you use a different wiring, you need to adapt the constructor parameters!

But you didn’t copy all example files to src/?
All these missing header files are right there in the example’s folder
Also this code looks very much like you have to comment out 2 of the 3 options. Make sure the right device type is selected one of those header files then only include that.
I don’t really know why, but it works now. Thanks very much
But unfortunately the same display problem as with the lib GxEPD. See link. y-axis is only visible from 6pt. It works with the Arduino IDE.
Then let’s discuss that in that other topic.
