Re: I2S ADC Mode ESP32-S3by ESP_Sprite » Thu Mar 10, 2022 2:58 am ADC DMA is a separate module in the ESP32S3 (not integrated into I2S anymore), although I'm not sure if currently the ESP-IDF ADC driver supports that......

Setting ADC_MAX_MEAS_NUM_DEFAULT (rtc_module.c) to 2 seems to fix this. No idea why though. Using I2S_CHANNEL_FMT_ONLY_LEFT orders the samples correctly, starting from the first pattern table entry. szmodz commented Mar 20, 2019 That's not the whole story though. There are some we...

Does the ESP32 hardware allow the I2S module to use the internal DAC and ADC simultaneously (i.e., streaming full-duplex audio)? Obviously the software support in esp-idf isn't there yet, but I'm curious if it will be possible in the future....
