routing reference voltage to GPIO pin while WIFI is enabled
Posted: Wed Jul 07, 2021 9:55 pm
Device: ESP32-S2-WROOVER
As ADC1 of ESP32-S2-WROOVER does not support an external reference voltage, I need to route the internal reference voltage of ADC1 to one of the GPIO pins. Therefore I use the command adc_vref_to_gpio. Unfortunately that does not seem to work while WIFI is enabled.
Is there any other way to route the internal reference voltage to any of the GPIO pins, while WIFI ist enabled?
