Hello, I am trying to record audio from SPH0645LM4H MEMS microphone using K82 - series MCU (Master).

The data sheet of the mic says that, no codec is needed and the audio data can be read directly from the mic through I2S  interface.

 

The mic data can be read when  SEL and WS llines are high. 

But I am unable to read any data, can you guys please help me with this?

 

Thank you
