touchscreen XPT2046 (ili9341) with esp32 s3

[fabse-hack]

hi kdschlosser and hi community :)

my code is working already, but the slider jumping and follow my touching with delay.

Jumping is in the middle of the display.
So, makes it sense to send you the debug log from the REPL ?

How i can improve the touchscreen ?
