ADC max input voltage? Quote Postbytorntrousers»Fri Dec 09, 2016 2:21 pm Hi, can anyone tell me the absolute maximum input voltage of the ESP32 ADC pins? I've seen a few blog posts suggesting 4.0 volts but I can't see that any any Espressif docs. ...
这两个调用adc1_config_width和adc1_config_channel_atten是至关重要的,因为校准特性需要匹配ADC配置。 //calibration values for the adc#defineDEFAULT_VREF 1100esp_adc_cal_characteristics_t*adc_chars;//Range 0-4096adc1_config_width(ADC_WIDTH_BIT_12);//full voltage rangeadc1_config_channel_atten(A...

Maximum input voltage on "Sig" pins = 3.3V (be careful with very old receivers, which may deliver 5V) It is recommended to use a fuse between your battery and the sound controller / ESC Supply for audio amplifier, shaker motor and LED: ...

Is anyone successfully using the ADC filters on the esp32s3? I supply a constant voltage to an input pin (GPIO 8 - ADC0) and measure the same standard deviation of the converted ADC values regardless of the filter setting (0/1/2/3/4/off). I am using the continuous mode driver. ...
