GxEPD(2) text is working, but not GFX or anything else

Hello,

I bought this eink display : https://fr.aliexpress.com/item/1005006165184542.html which contains a WFT0290CZ10 screen with white, black and yellow. Here is what I managed to get working:

  • GxEPD2 "Hello World" example
  • GxEPD2 "Hello World" example with a modified text, font and yellow color
  • GxEPD "Hello World" example

Every other examples involving GFX (from GxEPD or GxEPD2) compile and upload to my ESP32 but the display doesn't do anything, it stays as it is. The wiring I use is the one suggested in the library. So all the "Hello World" examples are working without editing anything except of course the display model selection part.

Did I miss something?

Best regards

NB: @ZinggJM I'm not sure about how we are supposed to ask question for your library this is why I'm mentionning your username on my subject, sorry if it's create spam for you

@hyrla2 , hi, welcome to the forum!

You may need to update the download link for the ESP32 package.
This, if you use an ESP32 and the package version you use is 1.0.6 or older.

Yes, I miss some additional information!

Please test with GxEPD2_Example.ino and report the display you selected or constructor you use.
Then report diagnostic output from the example, in a code window, please.

Yes, you chose the right place for questions. Mentioning me doesn't hurt, as I have disabled e-mail notification. Mentioning helps, as other responders notice that the question is directed at me. But I read most posts in the Displays section anyway.

Thank you for your reply!

My problem is now fixed. Following another tutorial I wired the VCC pin of the screen to a regular I/O port on my ESP32, which I think is not able to provide enough current. Now, everything is working geat, thank you.
