I get this error when compiling in Arduino

Do you the screen driver installed?

ok I added the epdiy library to the demo sketch and that solved the error however now it's asking for a display type

I was using the epdiy library direct from the epdiy/git and not from this git. I cleaned everything out and now it seems to work

G6EJD commented 3 years ago

Close the issue then?

Could you please explain more details about how had you fixed the issue ? I have the absolute same problem. Thank you.
