Hi,

I have a customer who needs to change the dynamic processing on the fly ( like time contant ). They want to do this via I2C. How do you accomplish this? They are using the ADAU1701 Sigma DSP and Sigma Studio.

Thanks

Hi,

I have moved this from the Blackfin Processors community to the SigmaDSP Processors and SigmaStudio Development Tool community. Please continue the discussion here.

Regards,

Craig.

Hello,

Your customer can change the dynamics this way:

Load your project, then change the desired dynamics parameter in the SigmaStudio GUI. Note what appears in the Capture Window, as shown below:

This shows what addresses within the -1701's parameter RAM to write to, and the parameter values to write.

2. Have your microcontroller duplicate this write. The safeload method is required for any run-time change to avoid clicks and pops in the output sound. For info on safeloading, see
