Hi,

I can see that digital microphones usually have PDM and I2S interface. I2S is supported by S32K148, so a microphone supporting this interface can be used. Notice that only S32K148 has this interface, it's not available on other S32K1xx. See the Synchronous Audio Interface module for more details.

Regards,

Lukas

Thank you very much lukaszadrapa‌ ,

if you have any demo code, how to configure the I2S interface mic to S32K148 ? It would be really helpful if I could get any sort of sample code,

and How can we transfer I2S format data to the DMA buffers??

Thanks and Regards

Hi chintusai6@gmail.com‌,

For all S32K1xx we deliver SDK which integrates also I2S driver. You have to install S32 Design Studio for ARM and after this install all available updates. To do this you should go to Help-> Check for updates. Last version should be BETA 2.9.0.

Best regards,
