Hello,
I need two read 2 ADC channels with a high sampling rate, at least 200kHz. So I used the I2S driver from Esp-idf to read the ADC channel and it works well for ADC1. However the driver doesn´t support to use the ADC2.
What can I do if want to read both ADC with the I2S? Is there any ...

every 256th sample is missing when I read ADC via I2S with DMA
Hello guys,
I want to use the ESP32s internal DAC and ADC with a very high sampling rate (200kHz), so I use the I2S with DMA.
When I connected the DAC to the ADC and I sent a 20 kHz sine wave (10 samples per period) to the DAC, I got an ALMOST correct result. I can see in my ADC data a period is ...
