i read at
https://learn.adafruit.com/adafruit-qt- ... ns-3119700
that there are 5 touchio capable pins.
in the visual pinout
they are marked `T5` - `T9`
in the guide for the Adafruit ESP32-S3 Reverse TFT Feather
https://learn.adafruit.com/esp32-s3-rev ... er/pinouts
touch is never mentioned.
in the visual pinout there are a bunch of pins mentioned with `T*`:
i tried with this code
Code: Select all
import time
import board
import touchio
import touchio
print("")
print("touchio_test.py")
while True:
touch_pin = touchio.TouchIn(board.D3)
print(touch_pin.value)
time.sleep(0.1)
i think it somehow interacts with the I2C functionality of the port??
