WebThe ADC conversion results provided by the ADC driver APIs are raw data. Resolution of ESP32 ADC raw results under Single Read mode is 12-bit. adc1_get_raw () adc2_get_raw () To calculate the voltage based on the ADC raw results, this formula can be used: Vout = Dout * Vmax / Dmax (1) where: Vout. Digital output result, standing for the voltage. WebADC2 is used by the Wi-Fi driver, so ADC2 is only usable when the Wi-Fi driver has not started. Three of the ADC2 pins are strapping pins and thus should be used with caution. Strapping pins are used during power-on/reset to configure the device boot mode, the operating voltage, and other initial settings ( link )
