I want to make an interrupt while deep sleep

[JorgeSayMe]

Good morning.

I am developing a tracker based on a ESP32.

I need to reset a counter variable every time I receive a '1' logic in GPIO 27.

I started using ext1 wake up (because I have different wake-up sources)

However, my problem is that I don´t want to wake up the ESP32 every time I get a '1' on GPIO27, due to the high consumption. Instead of that, I want an interrupt routine that resets my counter variable every time that I have a '1' on GPIO 27 while ESP32 is on deep sleep

Is this possible?

You may want to look into using the ULP for that.

You can configure an RTCIO interrupt without enabling wakeup. Read the int on wake, and clear your counter if set.
