@teastain Excellent, Terry, thank you!
I'm, too, struggling with the setup but I think I got it now, thanks to YouTuber "Volos Projects".
I'm on macOS (both, an Intel-based iMac and an M1 Max based MacBook Pro) and I'm using the Arduino IDE 2.0.
I was able to compile, upload and run the tft.ino example sketch that is provided here.
But I wasn't successful, yet, in running the factory.ino sketch provided here. I compiles and uploads successfully but it doesn't run. Only the LCD's backlight fades on, stays lit app. 2 seconds and that starts over and over again. Can be seen here.
I use the ESP32S3 Dev Module board, Flash Size 8MB and Partition Scheme 8M with spiffs.
I did copy the TFT_eSPI library that was provided by the manufacturer into the Arduino IDE's library folder – but apparently it's not used by the factory.ino sketch (no includes of header files from that library).
I is used by the tft.ino example and that works fine for me (although I don't quite understand the point of that demo (yet) – but that's another topic).
Anyone here who was able to run the factory.ino sketch successfully?
Cheers,
Stefan.
