Does SigmaDSP perform SCLK stretching for timing sync with USBi?
After some reliability issues with SigmaStudio ReadBack (both EVAL and custom hardware, alike), I am looking at the USBi bus in SPI mode with a logic analyzer, and it appears that the SigmaDSP might b

Not seeing I2C traffic on SCL2_M,SDA2_M pins with ADAU1463
My circuit board has SCL2_M and SDA2_M connected to a DAC, ADC, and two AD2437 chips. This I2C bus has pull-ups on the PCB, immediately beside the ADAU1463 pins, and then the traces continue to the AD

How to view I2C Read data
I am hoping to use SigmaStudio+ to debug the I2C link between an ADAU1463 and DAC chip. I added the I2C Read External Trigger, connected an On/Off button to the trigger input, and connected the output

Aardvark does not turn green for EVAL-ADAU1452REVBZ
I have ordered the USBi interface, but I am trying to use the Total Phase Aarkvark with the EVAL-ADAU1452REVBZ in the mean time. For some reason, nothing I do seems to turn the Aardvark Communication

Which Registers control SPI Mode and other configuration?
The datasheet warns that "The master port must be reconfigured in software before using a protocol other than the one configured at boot time." So, how is this done? Which Registers control this confi

Controlling DS1881 Digital Potentiometer from ADAU1463 for Analog Audio Volume (No External MCU)
Hi everyone, I'm working on a prototype board that uses the ADAU1463 DSP, and I’m experimenting with controlling the volume of an analog-only audio path (i.e., the signal does not enter the ADAU1463).

ADAU1462 TDM16 Serial IO Not Working
I'm currently trying to program the ADAU1642 and I'm having issues with both reading TDM16 signals in and writing it out at 44.1kHz with 32 bits per channel. I saw a similar post made about the ADAU16

Instable S/PDIF output with the ADAU1463
Dear members, The problem encountered most probably is related to a similar problem encountered previously with the ADAU1452: ez.analog.com/.../instabel-88-khz-s-pdif-output-with-the-adau1452 I’m curr

Adaptation of the Reverb algorithm to various sampling frequencies
Dear Friends, If I compile an IR-filter with fs set to 192 kHz the underlying biquad parameters will be optimized such that I get the required filter response for any signal that has a sampling freque
