There are several options for calculating the parameter values you should download to the SigmaDSP control port. Here are a few examples:

 

  • Open the capture window in SigmaStudio and change a parameter to a new value. The capture window shows you what address to download to and what values to write. It will also show if the write should be a block write, individual write, or safeload write.
  • Use the filter coefficient calculator (Tools...Fixed Point Filter Table Generator) to calculate values for filter coefficients. You can export these and include them in your microcontroller compilation.
  • Use the coefficient calculation equations in the SigmaStudio help file to calculate your own coefficients. You can also implement these equations in a system's microcontroller to calculate coefficients during system operation.
  • Use programs like MatLab to calculate IIR coefficients.

 

For complete listings of parameter addresses and values in a number of formats, use the "Export System Files" function in SigmaStudio after compiling your project. The "Export System Files" button is located in the main toolbar.
