Hi Terry, I'm back in business again!
And... I have solved the problems, thanks to this link:
Device declaration
My basic altitudemeter is working now. I still have to 'clean' my sketch. Afterwards I will post the code here.
Thank you again for helping me.

Hi Terry, this tick-tock works! I see the output in the Serial monitor
So, connection is OK
I use the board LilyGo T-Display-S3 an I can now compile, upload and run the display.ino example:-)
However, the factory.ino gives me many errors that seem to be related to the lvgl library. There are many lvgl libraries, which one do I need to install for the factory.ino to compile?
Again, your help is really preventing me from giving up!!
