Hello,

 

I need some help, I am trying to get some info since last 3 days.

1. in the aic3106 codec what is the format of sample_data?

2. How should I use the data to program my stuff.

3. Anything I try to change doesnt work, so I need the info how the data flows and how should I use it.

4.for ( sec = 0 ; sec < 10 ; sec++ )
    {
        for ( msec = 0 ; msec < 1000 ; msec++ )
        {
            for ( sample = 0 ; sample <48  ; sample++ )

these three loops are used in every section what does these loop do sec does the timing thing, sample does the number of samples , msec should deal with the freq but nothing happens when i change that , the output remains the same.

 

 

 

I need help regarding these things, it would be appreaciable if somebody could help me.

 

 

Regards

    Akshay,

    Are you asking about an example application, or is this code that you wrote yourself?  There are multiple example applications that you can look at to get a better idea how to interface with the audio codec chip on the EVM.  The BSL from Spectrum Digital is the simplest (or lowest level) option.

    If you have questions specific to the codec itself, I would recommend asking on the audio converter forum:

    Hope this helps.

    Hello,

    This is not my code this is the code inside the lin in function of the codec .I am asking how should I use the codec the , what is the data that I shall treat as input ?

    so that i can program with that particular input and hout should i send it back to get the output from line out.

    Till now I was treating the sample_data as the input acquired but I dont know what is the for mat of the data and how should I alter it.

    I try anything I get distortion or I dont see any change , so I am not understanding what is happening. I would appreciate if I could get some help with  this.
