Touch-sensitive pin T1 (GPIO 0) doesn't work

[rafaBG]

Hi friends,

I literally just got my hands on my first ever ESP32, so I am trying to figure out things.

I am testing the built-in touch sensors of ESP32, using the example project in the ESP IDF examples folder (https://github.com/espressif/esp-idf/tr ... _interrupt).

It works almost perfectly. The only problem is that the touch-sensitive pin T1, which is supposed to be GPIO 0, doesn't work. It just reads value 0 constantly. The documentation says that the ESP32 has 10 touch-sensitive pins, but I've also read that GPIO 0 is "reserved". So, if you can't use GPIO 0 as a touch sensor, why do they say it is touch-sensitive in the first place?

If anyone knows how to somehow "activate" the touch capabilities of GPIO 0, I would be very thankful.

Thank you in advance!

Did anyone have a similar experience?
