shutdown not working #448

Closed MHz000 closed 3 years ago

MHz000 commented 3 years ago

Hi Ed declared in Config pin_shutdown = 34
Save & Restart, source new compiled and flashed neithher set Vol = 0, Mute nor Stop resets pin 34 to GND wiring is ok What is missing, what wents wrong? Thank-you

GPIO 34-39 have no internal configurable pullup/down, you have to add a 10kohm resistor from the GPIO to 3.3V.

Maybe pin 34 in input only, I am not sure. Please check.

MHz000 commented 3 years ago

Ok, I'll check. In the source code? In one of the header files? Pls advice. Thank you

Nona, as output port there is no need for a pull up R Thank-you

NonaSuomy commented 3 years ago

34-39 are input only. This is not code related it is a limitation with the ESP32 hardware. I thought you were talking about a button input.

MHz000 commented 3 years ago

in main.cpp line 946: pinMode(shutdown_pin, OUTPUT);

in Config page WEB interface pin_shutdown = 34

something missing, wrong interpreted?

Nona thank-you for the hint, I'm not aware of that HW limitation. *) Try to find an other - useable - pin. Maybe Edzelf will give some advice how to use the shutdown function of ESP32-Radio.

*) my ESP32 pin map GPIO34/35 is yellow colored. Are output GPIOs blue colored?

using pin 7 GPIO17 => U2_TXD as shutdown works fine now! Set: pin_shutdown = 17 in Web Config page Thank-you Nona for pointing me to special HW caracteristics
