Audio DAC using ADSP-21489

Hi All, 

First of all, I already used SigmaStudio for parametric EQ using ADAU1701, never used Sharc tools.

I have a ES9038Pro DAC that work with a USB to I2S converter.

My goal is to interface a ADSP-21489 between the USB to I2S converter and the DAC, to add FIR EQ DSP in my audio system.

The USB to I2S converter will be (I will try both) :

Amanero COMBO384

OR

Xing U30

Both provide PCM and DSD output, but I'll not use DSD.

They are "clock MASTER", they also provide :

-Master clock

-FS clock

-Bit clock

I'm a bit lost about the way to rich my goal with the "Sharc univers" and I'd like to get your guidance.

For now, tell me if I have well understood.

-I need to find the way to set DAIs as INPUT and set it well for :

   -Master clock (Slave from the USB to I2S converter)

   -FS clock (Slave from the USB to I2S converter)

   -Bit clock (Slave from the USB to I2S converter)

   -DATA (From the USB to I2S converter)

-I need to find the way to set DAI as OUTPUT and set it well for :

   -DATA to the ES90489 (Only DATA because the MCLK/FSCLK/BCLK are shared from the USB to I2S converter ?)

-I need to find the way to write my settings (I/O and EQ) in the Sharc firmware.

I have installed CCES and Sharc module in SS but never used it for now.

May you guide me to start to learn what is needed to reach my goal ?

Excited to get skills thanks of you !

Regards
