void analogSetWidth(uint8_t bits); ADC 连续模式 ADC 连续模式是一种 API,设计用于在后台对多个引脚执行模拟转换,具有在完成这些转换后接收回调以访问结果的功能。 该API 允许您指定单个周期内每个引脚所需的转换次数及其相应的采样率。该函数的结果analogContinuousRead是一个结构体数组adc_continuous_data_t。这些...
I upload the sketch and read the analog input of ESP32 I read 0. I know that the sensor work since it works with arduino.So, I suppose that ESP32 cannot read the analog input... Do I have toinclude any library into my sketch related with ADC? Thankin advance Edje11 ...
