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

Send an address with I2C according to a specific voltage value applied to an ADAU 1701 DAC
I have to read 5 different voltage values on ADC3 of DAU1701. I thought I would use a VCO as an attached figure and then convert the frequency into a specific address corresponding to each single freq

"Add" Features Does Not Simulate in Sigma Studio
Hi Everyone, I'm using the Stimulus and Probe blocks in simulating the behavior of the ADAU1772. All works fine until I try and split part of the signal with the T Connection 1772 and then after some
