how can i save the pcm data into the memory using I2S and DMA with STM32F217IG ??

Hi,

I'm using STM32F217IG microcontroller with TLV320AIC1106 audio codec for recording and playback.

I need to generate .wav file with PCM 64kbps sampling.

The codec is able to to give PCM Data of 8-bit u-law

for this i want to use I2S with 16 bit PCM with 4kHz sampling.

Please help me in achieving this
