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 ,

    Replying to your question, I'm working on demo example. And No! I didn't get the audio output using pre-built DXEs. I've followed exactly what the quick start guide says and after link-compile-download, I got assertion failed error on my console in CCES(The code was under debug mode) (I get this error once in a while. I never got any audio output till now though). I've attached the picture below. Please check.

    Also, as i mentioned earlier, the demo example has about 27 errors.

    The error is in the line inside InitializeFW function as highlighted below.
