Touch wake up ESP32-S3
Posted: Wed Oct 12, 2022 2:11 pm
Hello,
I'm trying to build an application for an ESP32-S3. I would like to wake the device up from deep-sleep using a touch pad. I found this example: https://github.com/espressif/esp-idf/bl ... le_main.c
The problem however is that this seems to be written for older ESP32 models. To enable the touch-wake up you need to set a threshold. Once the touch level is below this threshold, the device will wake up.
The problem however is that with the ESP32-S3 the touch value increases when it's being touched and therefore the threshold should work the other way. Do you have examples on how to implement this?
Thanks!
