Detect long touch upon wake up from deep sleep

Q&A Forum › Category: ESP32 › Detect long touch upon wake up from deep sleep

Jas asked 6 years ago

Hi,

I am trying to detect if the user is still touching the pin T2 after ESP32 wakes up.

touchAttachInterrupt(T2, callback, Threshold);

Since I cannot use digitalRead(T2)==LOW because this pin it is not HIGH or LOW, it is threshold based.

I would like to use the same pin for touch wakeup and when device wakes up I would like to detect that the pin is still touched for 2 seconds etc. and do something.

Any ideas?
Thanks

Never mind, I found the answer, i.e. is to use callback.

Thanks
