SPI protocol problems 1701

Hi!

     I found some problems on getting working the spi controll protocol in AD1701.

I'm using the USBi programming interface and the EVAL-ADAU1701MINIBZ. With standard I2C my project works well, but if I try to change the I2C in SPI in the hardware configuration (from USBi and ADAU1701) it seems there is no comunication between ADAU1701 and USBi on every change of parameters.

When I change the register controll, I can read parameters, but also when I click 3 times the Write ALL Button, but I can't have controll on DSP.

I need one working example or some specs to getting this protocol working.

I finally need to controll this device with a PIC and possibly the SPI with E2PROM, but at least I need to get working the USBi interface in SPI addressing on ADAU1701.

 

Thanks!
