T-Display-S3 Touch Screen Examples (with HEAVY comments)

[highwayman]

Greetings all!

Like the title say, I want to create a super basic application that uses the touch screen capability of this module. I have already reviewed the example “touch_test.ino” for hours and I do not understand the 24 of the 103 lines that are related to the touch screen.

Does anyone have any heavily commented code that details what each group of code is doing? I’ve tried watching Arduino examples, but I’m not successful (or skilled enough) in porting it over to the T-Display-S3.

I’m not even sure what pins are used for the touch screen. If it’s an I2C module used for touch screen communication, which chip?
