SigmaStudio+ Indirect Parameter Accees Table
In old SigmaStudio you could add a parameter to the IPAT with a simple mouse right-click. Is there a similar feature in SigmaStudio+? I can only add it via the IPAT table but it gets annoying when the

ADAU1452 + AD1938 Setting I/O problem
Hello, I bought a two-board set consisting of an ADAU1452 DSP and an AD1938 codec. I managed to get it up and running using a modified '192i2s.dspproj' test file. The sound quality is excellent. In my

SigmaStudio+ Sample rate propagation
I found out that the T-Connector would not propagate sample rate downstream. Remove the T-Connector and connect straight to the next block and the block's sample rate follows upstream. Does anyone hav

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
