Basic volume control on ADSPSC589 ez board.

I've attached a sample schematic from the example folder in sigmastudio which used to control volume and mute. In the schematic, there are 4 RCA inputs, 2 s/pdif inputs and 6 RCA outputs. I've used demo DXE (CCES) for ADSPSC589 given in the example folder of software module.

I have 1 RCA mic as input and 1 RCA speaker as output.

Can someone tell me how the processor knows which pins are input and which pins are output? That is, how and where to assign these pins as input and output. I've searched in manual but i couldn't find it. 

My second question is, if i want to use just 1 input and output how do i assign it in the code?

New here, kindly help. Thank you.

  • Hi,

    Please follow the same steps given in section 6.2 Getting Started with Example Schematic

    C:\Analog Devices\SoftwareModules\SigmaStudioForSHARC-SH-Rel4.1.0\Docs "AE_42_SS4G_QuickStartGuide.pdf"

    Here only the change, you need to select DXE you have generated in project debug folder, for both CCES debug configuration and SigmaStudio Schematic.

    Ans 1: No need of any softconfig.c change. Schematic creation, you need to refer example and you can change input and output as you want. Hardware setup, please refer attached image for input/output connection.

    Ans 2: You can give or get input/output at any time, only thing you should follow section 6.2 Getting Started with Example Schematic steps carefully.

    whether you got audio output for the pre-built DXE with Example schematic? If yes then you can easily modify schematic for your requirement.
