GC9A01 and Xiaio esp32

Hi there,
I can help you work through it, I’m a "teach a man to fish " kind of person. It wouldn’t benefit anyone else but you, which is counter to the spirit of a PUBLIC forum. Post up what you have and others too will make some very good suggestions. You can read , So I now that already. That’s all you need to do. When your done, it will serve you better to know how and why it works.
Start with loading the proper Board Support Package, a.k.a BSP, the manufactures… nordic, Espressif, x, y, & Z make them available for Arduino IDE. I know now you know this now , so get the correct one going first. Run your compile and be sure in your settings for the IDE it set for “verbose” (tells you a lot)
about the Ingredients mix. (not necessarily how it’s made) that’s almost last but I digress…
If everything compiles but doesn’t display, You have a Choice…

  1. run the Read_User_setup.ino and look at what comes out the serial port.
    it should look like what I posted.
  2. check the edit for what you have enabled there’s only one choice.
    Note , if you have the Round display wiki open on another tab, the stps are documented there there’s ONLY two. FYI :+1:
    NOTE: when you have it (driver recognized) you will see the display right away too.

So what you got?
