Double write in SigmaStudio 4.1
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?
Thank you,
Gennady
sorry, not the invert cell, but delay and equalizer definitely.
Hello Gennady,
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.
Best regards,
Bob
It is my impression also.
Thank you,
Gennady
