hi
i can't obtained the waveforme of signal in graph time ?
//sine8_buf.c sine generation with output stored in buffer
#include "DSK6713_AIC23.h" //codec support
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 LOOPLENGTH 8
#define BUFFERLENGTH 256
int loopindex = 0; //table index
int bufindex = 0; //buffer index
short sine_table[LOOPLENGTH]={0,707,1000,707,0,-707,-1000,-707};
int out_buffer[BUFFERLENGTH]; //output buffer
short gain = 10;
interrupt void c_int11() //interrupt service routine
{
short out_sample;
out_sample = sine_table[loopindex++]*gain;
output_left_sample(out_sample); //output sample value
out_buffer[bufindex++] = out_sample; //store in buffer
if (loopindex >= LOOPLENGTH) loopindex = 0; //check for end of table
if (bufindex >= BUFFERLENGTH) bufindex = 0; //check for end of buffer
return; //return from interrupt
}
void main()
{
comm_intr(); //initialise DSK
while(1); //infinite loop
}
