Does arduino for esp32s2 not support i2s ？

[tumuyan]

I try to build and download the i2s example (ESP32\examples\I2S\HiFreq_ADC)，but it shows build error.
then I find this folder has a file named as .skip.esp32s2
Does arduino for esp32s2 not support i2s?

It supports I2S, but the peripheral is not connected to the ADC SAR. SOC_I2S_SUPPORTS_ADC_DAC is only defined for esp32, so it probably won't be available in s3 either.
The replacement is the ADC DIG driver, which should support even faster sampling and DMA. https://github.com/espressif/esp-idf/blob/master/components/driver/esp32s2/include/driver/adc.h

Thanks for your reply, but I find it's really hard for me to use ADC driver to get and decode data

[lbernstone]

This should allow sampling up to a theoretical max of 400kS/sec on esp32s2 fed to DMA (which can then be written to psram).
The HAL is still cooking in the oven. https://github.com/espressif/esp-idf/blob/master/components/hal/esp32s2/include/hal/adc_hal.h
Ping this issue in a couple months and I will take another look. Hopefully espressif will have an example in idf by then.

hello, is it too later to ask for this same topic? I got compiling error: 'i2s_adc_enable' was not declared in this scope when compiling: Simple 1Msps ESP32 Oscilloscope - DEMO VIDEO ?
thanks.
