Dear every body,
I just receive eval board mediaworks with ADAU1467.
I seen many thing for my project in Delta sigma studio.
Now with a very basic design i'm trying to load program with TinySine USBI. But something is missing.
My project (to begin) is to use the SPDIF input (with a 44,1KHz signal) and transfert it directly to the analog output1 channel 0/1 as below.
But i'm unable to confirm that the program is inside the DSP and then the systeme is not working...
Maybe some one can help me to start this first step of project?
Thank you...

Hello Again,
I'm able to use analog input and transfert it directly to output, i also try internal function as EQ and internal volume and that ok.
Then my problem is to use SPDIF Input...

problem is solved. Was wrong register settings in HW-Config tab.
If anyone runs into problems with S/PDIF, you can find details in the Userguide EVAL-ADAU1457Z (REV.0) on pages 12 to 16.

Dear, i'm doing many thing with this ADAU1467 this is crazy.
I have a question now before going inside a crossover from the 4 I2S input i want to be able to select one input with Stereo Multiplexer but the thing is that's i want to control this multiplexer via the second I2C input (SDA2m pin 31 and SCL2m pin 30) controled by a PIC32MX.
How can i link the box I2C in te design to the second I2Cm input?
I really don't know how to do i just design an idea to make you understand me.

Using I2C is new to me, but here's my take on using it: The 1452 has dedicated pins (see below) for the I2C slave port . So you don't want the GPIO_0 block, just the I2Cread block.
SS/ADDR0 Address 0 (Bit 1 of the address word, Input)
CCLK/SCL Clock input
MOSI/ADDR1 Address 1 (Bit 2 of the address word, Input)
MISO/SDA Data (bidirectional, open collector)
Here's a couple of links (besides the ADAU1452 datasheet) I found helpful:
