今天在使用ESP32-S3的ADC时,需要高速ADC采样,参考example中的持续采样代码设定了ADC,调用adc_digi_controller_configure(&digi_cfg)提示ADC bitwidth not supported。 调用部分代码如下: [Codebox] void ESP32ADC::setHighSpeedADC() { // adc_digi初始化 // controller初始化 adc_digi_init_config_t adc_dma...
完成上述结构体参数配置之后，可以将结构传递给 adc_digi_controller_configure () 函数，用以实例化ADC...

The sampling frequency given in the adc_digi_configuration_t structure before calling adc_digi_controller_configure() doesn't seem to have any purpose but to check for min max value. The variable conv_limit_num inside adc_digi_configuration_t seems to cause double variables when containing high...
