Hi @felmue,

after your reply (thanxxxs!) I tested again. And this time it worked :-))) I must have messed up your original example code 'til the failure point with my supplements. This time I sticked rigoroulsy to your formulation. Success!

Regarding your literature hints: Thanks again. I had gone through relevant randomnerd tutorials before. That's how "esp_sleep_enable_touchpad_wakeup()" came to my mind... a dead end road as I learned from your remarks. The Espressif sleep docu I have yet to read.

Best,

hi @felmue,

meanwhile I tested your proposed solution. Unfortunately, it just lead to a continuous reboot cycle without any sleep state ever reached :-((
Substituting "deep_sleep" for "light_sleep" did not change anything.

Grepping in my Arduino libraries i found "gpio_wakeup_enable" and "esp_sleep_enable_gpio_wakeup" to be declared in various header files under
~/.arduino15/packages/esp32/hardware/esp32/2.0.5/...
~/.arduino15/staging/packages/2.0.4/...
~/.arduino15/packages/m5stack/hardware/esp32/2.0.4
but not under ~/Arduino/libraries/M5Core2....

The CST_INT definition was found under ~/Arduino/libraries/M5Core2...
whereas GPIO_INTR_LOW_LEVEL again only in the ~/.arduino15 branch

Is the multitude of declarations under .arduino15 or the absence from the M5Core2 libraries a potential explanation for failure? Could it be, that your solution works fine with one of the ESP32 development boards but not with the M5Core2?

Appreciating your response.
Best, digs

hi @felmue,

thanks a lot for the fast reply. i'll try your proposed solution asap. seems i've missed out on this basic solution, although i did quite some search before and never stumbled across such a piece of code. however, i'll get back to you.

have a good day, digs

Hello,
is there a way to make the M5Core2 wake up from sleeping modes by touching the screen?
I'm aware of the "esp_sleep_enable_touchpad_wakeup();" function, but I just can't get it to do what it is supposed to. Using "touchAttachInterrupt(G27, callback, Threshold);" does not help. Furthermore, except for G27, all other pins I tried to tie to this function (0,2,4,12-15,27,32,33) lead to permanent reboot cycles. With G27, at least this issue did not occur.
Your response is highly appreciated,
digs
