Hi

I need to interface the LPC4350 to an external audio CODEC using TDM (I2S). The External CODEC will be the master providing the LPC four audio channels which are to be processed and then brought back to the external CODEC for playback. I guess I'm just asking for a ping-pong scheme.

Is such project exist already shared - I searched the NXP site and didn't find anything?

Cheers

How do you support 4 channels with I2S ?. Presumably you are using both I2S interfaces as if you TDM them there is no way of identifying the individual channels.
