I²C stucks with Adafruit STMPE610


I bought a STMPE610 Resistive Touchscreen Controller with a 2.4" TFT Touchscreen Display from Adafruit.
The display works as expected but the touchscreen doesn't.

I used this library (GitHub - adafruit/Adafruit_STMPE610: Arduino library for STMPE610/811 resistive touch screen controllers) with the provided example "TouchTest" to test the touchscreen controller with I²C.
I also tried SPI but no success :frowning:

When ts.begin() is called, the code stucks at this point and I don't get an answer in the serial monitor.
The first times I got the error that the controller was not found but after rewiring it, the code stucks.


Do you have a clue for a solution?
