How to initialize I2S as a slave in FRDM_K22F

Hi,

 

I'm working with FRDM_K22F and I just initialized I2C as a master and connected K22F to WM8731 CODEC. the next step that I'm gonna do is to initialize I2S in K22F as a slave so that it receives data from ADC port of CODEC and after that send this data to transmitter and transmit it to DAC port of CODEC.

 

My problem is that as I searched a lot in the internet I don't know exactly how to use FIFO without interrupt or DMA to know when data is ready in the receiver and send it to transmitter.

Can anyone help me with this issue?

 

Thanks,
