this is my program
//delay.c Basic time delay
#include "DSK6713_AIC23.h" //codec support
#include "DSK6713.h"
Uint32 fs=DSK6713_AIC23_FREQ_8KHZ; //set sampling rate
#define DSK6713_AIC23_INPUT_MIC 0x0015
#define DSK6713_AIC23_INPUT_LINE 0x0011
Uint16 inputsource=DSK6713_AIC23_INPUT_MIC; //select input
#define BUF_SIZE 8000
short input,output,delayed;
short buffer[BUF_SIZE];
int i;
interrupt void c_int11() //interrupt service routine
{
input = input_left_sample(); //read new input sample
delayed = buffer[i]; //read output of delay line
output = input + delayed; //output sum of new and delayed
buffer[i] = input; //replace delayed sample with
if(++i >= BUF_SIZE) i=0; //new input sample then increment
output_left_sample(output); //buffer index
return; //return from ISR
}
void main()
{
for(i=0 ; i<BUF_SIZE ; i++)
buffer[i] = 0;
comm_intr(); //init DSK, codec, McBSP
while(1); //infinite loop
}
and when i debug
