Setting up an ADC with an ADAU1463 over I2C
Hi, I'm trying to Settup an ADC through I2C. The ADAU1463 operates at Selfboot Mode, so I have to settup the ADC with the DSP. I've tried to send I2C writes with the "Master Control Port IO" block, bu

Why is SigmaStudio 4.5 loading DSP Program Data 5 times?
In the auto-generated default_download_IC_1() function at the bottom of the (projectname)_IC_1.h file, SigmaStudio 4.5 generates 5 identical SIGMA_WRITE_REGISTER_BLOCK calls to load the DSP program da

Sigma Studio IC-1 address incorrect
The 1701 literature (page 23, table 16) reports a bunch of device addresses with the address and R/w# combined. This is wrong, as the address is 7 bits not 8. If addr0 and addr1 are tied low, the devi
