TMS320 C6713 AIC23 codec

Hi,
Which example code are you using and version please ?

#include "dsk6713.h"
#include "dsk6713_aic23.h"
#include "DSKintr.h"

#include<stdio.h>
#include<math.h>

DSK6713_AIC23_Config config={0x0017,0x0017,0x00e9,0x00e9,0x0011,0x0000,0x0000,0x0043,0x0081,0x0001};
void main(void)
{

short gain = 10;
Uint32 sample=0;
Int32 i;
Int32 y[1000];
//Int32 y1[100];
//Int32 y2[100];
//Int32 y3[100];
//Starting the DSK and Codec

//DSK intialization
DSK6713_AIC23_CodecHandle hCodec;
void intr_reset(void);
DSK6713_init();
hCodec=DSK6713_AIC23_openCodec(0,&config);
DSK6713_AIC23_setFreq(hCodec,DSK6713_AIC23_FREQ_32KHZ);

while(1)
{
for(i=0;i<1000;i++)
{
while(!DSK6713_AIC23_read(hCodec, &sample));
y[i]=hCodec;
// y2[i]=y[i];
// y3[i]=y2[i];

/*}
for(i=0;i<1000;i++)
{*/
hCodec=y[i];
while(!DSK6713_AIC23_write(hCodec, gain*sample));
}

}
/*
for(i=0;i<1000000;i++)
{
while(!DSK6713_AIC23_write(hCodec, gain*sample));
}
*/
}



I don't know where in memory y[i] and hCodec is getting stored.

Hi,

Thanks for your post.

I guess, all the digital input audio samples used in the above code  should be stored in the internal RAM of C6713 DSP. Please check the C6713.cmd linker command file in your .ccs project which would provide you where all the code and data sections are mapped to which part of memory. I would reecommend you to go through the lab doc as below which involves programming the TMS320C6713 DSP Starter Kit (DSK) module:

http://ecee.colorado.edu/~fmeyer/class/ecen4532/lab6.pdf

The AIC23 codec on DSK6713 is connected to two multichannel buffered serial ports (McBSPs), McBSP0 and McBSP1. McBSP0 is used to send commands to the codec control interface while McBSP1 is used for digital audio data. Once the codec is configured, the control channel (McBSP0) is normally idle while audio data is being transmitted on McBSP1.

You can find a simple program from

Wiki: http://processors.wiki.ti.com/index.php/File:C6713_audio_minimal.zip

You could also download the board support files from specturn digital webite on the prerequisites on the wiki below:

Thanks & regards,

how to access a memory location in c6713?

i am trying this but it comes with error.
Int32 y[20151];
y[0]=0x00000058;

The size of the y array is quit large you can use the memory viewer to check the memory and then you can use the graph to see the input graphically
for memory view go to view -> memory and enter the address of the data that you want to view
