TLV320AIC3262EVM-U: I2S master/slave configuration via the CodecControl Software and "streaming" data between ASI

Hi,

I'm currently working with the TLV320AIC3262EVM-U for a project. For now i'm trying to understand how to configure the Codec master/slave I2S mode for each Audio Serial Interface (ASI).

Here is a drawing of my set-up:

For now the STM32 give an I2S signal wich is composed of 2 channels with a bitdepth of 16. The STM32 generate the Bit and Word Clock.

What i'm trying to do is to connect the STM32 to the ASI#2 inputs and then to stream the output of the ASI#2 to ASI#1:

  • Data In to the middle pin of w29
  • WCLK to the middle pin of w32 for ASI#2 and w28 for ASI#1
  • BitCLK to the middle pin of w30 for ASI#2 and w26 for ASI#1

Here is the configuration in the CodecControl software:

Am I using the right configuration for the job ? Or Is there any mistake in my set-up/understanding ?

Thank you for your time.

Simon
