There is currently no i2s nrfx driver in Zephyr. Check out Zephyr issue 11702-->

https://github.com/adamkondraciuk/zephyr/tree/i2s_test, where a developer has added support for I2S.

Both driver and dts support is added:

The code above was written for a quite old version of NCS, so you may have to modify it a little to make it work with a newer version

Sir , I examine 96b_argonkey microphone example program after this I created new project for my board (nrf52840dk) with same parameter and configuration , then I compile my code , but during this process i got error this error is about pdm driver after checking .dts file for both 96b_argonkey and mrf52840 , I marked 96b_argonkey has i2s driver in dts file but unfortunately nrf52840 has don't have nay i2c driver . So what can I do sir ... How will i add i2s driver on dts file because this file made by compiler not by user .

Are you encountering the issues during compile time or run time? I assume during building/compiling.

What changes have you done?

What error message did you get? Could you attach the error(s) you are getting?

Best regards,

Simon

Check out the example \zephyr\samples\boards\96b_argonkey\microphone. You may have to modify it for your use, but it should be a good starting point.
