Hi Dear, 
        So did u find answer to your query? I am really a new comer in DSP domain and unknown
to working C5510 in detail. I want to read audio input from mic and store it.Then i want to
play it back to headphone.

This is my main():

void main()
{
    
    DSK5510_AIC23_CodecHandle hCodec;
    Int16 i,j,k,left,right;
    Int16 input1[8000];
 	Int16 input2[8000];
    /* Initialize the board support library, must be called first */
    DSK5510_init();

    /* Start the codec */
    hCodec = DSK5510_AIC23_openCodec(0, &config);

    /* Generate a 1KHz sine wave for 5 seconds */
    for (i = 0; i < 10; i++)
    {
        for (j = 0; j < 8000; j++)
        {
            /* Read a sample from left channel */
            while (!DSK5510_AIC23_read16(hCodec, &left));
            input1[j]=left;
            
            /* Read a sample from right channel */
            while (!DSK5510_AIC23_read16(hCodec, &right));		 
            input2[j]= right;            
	    }
		       
     }
    for (i = 0; i < 10; i++)
    {
	  for(k=0; k<8000;k++)
	  {
        while(!DSK5510_AIC23_write16(hCodec, input1[k]));
        /* Send a sample to the right channel */
        while(!DSK5510_AIC23_write16(hCodec, input2[k]));
	  }
    }
    /* Close the codec */
    DSK5510_AIC23_closeCodec(hCodec);
}

But it is not giving any output. What to do?
kindly help me where i am going wrong. I will be waiting for ur reply

regards,
Umer

First I would try something very simple to verify your DSK board, tool
set-up, build options, memory map, and other basic factors are Ok:

void main() {

DSK5510_AIC23_CodecHandle hCodec;
Int16 left,right;

    /* Initialize the board support library, must be called first */
    DSK5510_init();

    /* Start the codec */
    hCodec = DSK5510_AIC23_openCodec(0, &config);

    /* Audio loopback */
    while (TRUE) {

      while (!DSK5510_AIC23_read16(hCodec, &left));
      while (!DSK5510_AIC23_read16(hCodec, &right));

      while(!DSK5510_AIC23_write16(hCodec, left));
      while(!DSK5510_AIC23_write16(hCodec, right));
    }

    DSK5510_AIC23_closeCodec(hCodec);
}

This should enable audio loopback -- you should hear whatever is on the
inputs.  Does that much work?  If so, then you can go step-by-step to add
the functionality you need, testing each step carefully.

Also, here is a nice page for generating a sine wave with DSK 5510:
