Hello folks, I am looking for a funcional sample to reading two ADC channels using I2S & DMA. Every part I have found does not work or does not even compile without erros... Thanks

I forgot to mentioned that I used IDF 5.1.2. I am trying to get a i2s buffer with two interleaved ADC channels readings such 3 7 3 7 3 7 ... I am newer in IDF development but I think it should be easy for who has some skill on it... Any help will be very very appreciated. Thanks

Some posts like this:

ensure that is possible to read multi channels into a DMA buffer but they do not tell how !!!
