I am working on a project with ADAU1761.
By some reason when changing some parameters in SigmaStudio 4.1, the capture window shows that data is written twice - same data to the same addresses. It happens with the invert cell and with equalizer, for example. When equalizer slider changes position, the capture window shows that safeload write of 5 words takes place, and then the same exactly safeload write is repeated.
I don't see any reason for this. Is it a bug in a SigmaStudio 4.1 or it's really necessary?
sorry, not the invert cell, but delay and equalizer definitely.
As you would expect, it's not necessary to load these parameters twice. I built a little project in an attempt to reproduce the double loading you're experiencing. When changing the first filter from 1 KHz to 2 KHz, it loads the set of five IIR coefficients just once:
Thus I can't explain why it's occurring in your case. I'm using SigmaStudio 4.1 on Windows 10 x64 with a ADAU1761 eval board and USBi ver. 1.3.
It is my impression also.
