@ajb2k3 I tried to reinstall Arduino IDE 1.8.9 and the library M5Stack, the only one included in my code but nothing changed, always the same error!
Thank you for your help :(

Hi, can anyone help me?!
I cannot compile anything with the Arduino IDE, due to the the following message:

Arduino:1.8.9 (Mac OS X), Scheda:"M5Stack-FIRE, Enabled, 921600, None"

/Users/Fabrizio/Documents/Arduino/libraries/M5Stack-master/src/utility/Power.cpp: In member function 'void POWER::powerOFF()':
/Users/Fabrizio/Documents/Arduino/libraries/M5Stack-master/src/utility/Power.cpp:360:35: error: 'ESP_SLEEP_WAKEUP_ALL' was not declared in this scope
esp_sleep_disable_wakeup_source(ESP_SLEEP_WAKEUP_ALL);

                               ^

What is happening?
I reinstalled the Silicon Labs drivers and the M5Stack library (version 0.2.8) but nothing changed...

Thank you very much

Hi Dominik,
thank you for your help.
Unfortunately I’m not so expert to be able to read (and to understand) the IP5306 datasheet.
I hope someone from M5Stack development team will reply to my (and to your) question.

Thank you
Fabrizio

No one knows about tha residual voltage on power pins, when the M5Stack is OFF?
Can anyone help me?

Thanks

Hi, I’m developing a sport stopwatch for curling training, based on M5Stack ESP32, gray version.

I’ve seen that, when the ESP32 is switched off, there are inexplicably about 1.90 and 0.7 V, respectively on the 5V and 3.3V pins.
This could be a big problem, for the fact that I need to connect the Xbee radio system, I use to riceive pulses from laser triggers, to the 5V pin and, due to this residual voltage on power pin, I risk to drain the battery for nothing.

Can anyone help me?

Thank you very much.
Fabrizio
