No programming in 192KHZ, ADSP21489, SStudio 4.5


I cannot program the evaluation board with Sigma Studio,
If I put 192KHZ in sampling frequency, on the other hand, it works, if I put 48KHZ.

Please explain to me how to make it work at 192KHZ?

Best regards,

  • Hi,

    The ADSP-21489 application is running at 48KHz sample rate by default, so you need to modify the application and regenerate LDR file for 192KHz.

    If you are using SigmaStudioForSHARC-SH-Rel2.2.0 the CCES application project available in following path,

    C:\Analog Devices\SoftwareModules\SigmaStudioForSHARC-SH-Rel2.2.0\Target\Demo\ADSP-21489

    Just try changing compiler preprocessor in project settings as APP_SAMPLING_RATE=SAMPLING_RATE_192K and rebuild application to generate LDR file.

    The regenerated LDR file can be used in SigmaStudio for running 192KHz processing.
