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.

Presumably you are using both I2S interfaces as if you TDM them there is no way of identifying the individual channels.</SPAN><BR /></BODY></HTML> Wed, 15 Jun 2016 18:50:36 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Interfacing-an-external-audio-codec-to-the-LPC4350/m-p/566972#M17435 lpcware 2016-06-15T18:50:36Z
