Wait. We are preparing demo now.
We'll provide it once we have prepared well. We do not want to provide unmature one. Sorry for the delay.

Looks like it's live

The example is wrapped up in FreeRTOS but it should be possible to untangle it.

Hi,

Great example and I2S driver,

I would like to connect MEMS I2S microphone,

it require I2S read task, so i made few code changes --> that still doesn't work

PIN_FUNC_SELECT(PERIPHS_IO_MUX_MTDI_U, FUNC_I2SI_DATA);
PIN_FUNC_SELECT(PERIPHS_IO_MUX_MTMS_U, FUNC_I2SI_WS);
PIN_FUNC_SELECT(PERIPHS_IO_MUX_MTCK_U, FUNC_I2SI_BCK);
...
SET_PERI_REG_MASK(I2SCONF,I2S_I2S_RX_START);

Can you please help to enable getting I2S driver to read from Microphone?

Thanks,
Roie
