How do I change the sample rate of my SigmaStudio system?

ADIApproved

on Oct 12, 2009

The default sample rate for SigmaStudio projects is 48 kHz. I want to run my system at a different sample rate. How do I do so?

Sorry, but I have the same question but now for my ADSP-SC589_EZ evaluation board, which is not included here.

Are there any updated instructions on this issue?

Hello bnilsson,

I would post this question on the SHARC section of this forum.

SigmaStudio will work the same way for the SHARC DSPs, the sample rate at the top of the window is only for SigmaStudio to properly program code that needs to know what the sample rate is. It is up to you to be certain that the registers in the DSP are properly set and the clocks going to the part are correct to obtain the desired sample rate inside the DSP. SigmaStudio does not know what rate the DSP is actually running at.
