touchRead(32) and touchRead(33) pins are swapped

Postby OutOfLine » Thu Oct 15, 2020 6:29 am

After some long debugging sessions I just found out that the Arduino function touchRead(pin) swaps pins 32 and 33. So touchRead(32) does in fact check pin 33 and vice versa.
Quite unexpected result ;)
Will have to explore further when I'll have the time...

Somehow my follow up has disappeared, so I summarize:
The issue is in the esp32-arduino software.
Please react in the thread in the Arduino subforum
