Re: esp32s3 ADC sampling rate
Follow-up to this question. It looks like the main way maximum ADC frequency is controlled in the driver is through: 1. SOC_ADC_SAMPLE_FREQ_THRES_HIGH in soc_caps.h which controls absolute maximum sampling_freq that can be programmed 2. ADC_LL_CLKM_DIV_NUM_DEFAULT in adc_ll.h that controls the divis...

esp32s3 ADC sampling rate
I have an application using esp32s3 where I want to sample three channels through ADC1. If I program a sampling rate of 3000 samples/sec, is it 3000 samples/sec per channel or 3000 samples across all channels. i.e. Do I see signal through channels 1, 2, 3 sampled at 3000samples/sec each, or 1000 sam...
