Tool/software: TI C/C++ Compiler
I am new to LCDK, I am trying to compile sine wave generation example. Can you guide me as to how to setup the project.
I will appreciate if you can walk me through the procedure to build the project.
My file has the following code
// L138_sine48_buf_intr.c
#include "L138_LCDK_aic3106_init.h"
#define LOOPLENGTH 48
#define BUFLENGTH 256
int16_t sine_table[LOOPLENGTH] =
{0, 1305, 2588, 3827, 5000, 6088, 7071, 7934,
8660, 9239, 9659, 9914, 10000, 9914, 9659, 9239,
8660, 7934, 7071, 6088, 5000, 3827, 2588, 1305,
0, -1305, -2588, -3827, -5000, -6088, -7071, -7934,
-8660, -9239, -9659, -9914, -10000, -9914, -9659, -9239,
-8660, -7934, -7071, -6088, -5000, -3827, -2588, -1305};
int16_t sine_ptr = 0; // pointer into lookup table
int32_t buffer[BUFLENGTH];
int16_t buf_ptr = 0;
interrupt void interrupt4(void) // interrupt service routine
{
int16_t sample;
sample = sine_table[sine_ptr]; // read sample from table
output_left_sample(sample); // output sample
sine_ptr = (sine_ptr+1)%LOOPLENGTH; // increment table index
buffer[buf_ptr] = (int32_t)(sample); // store sample in buffer
buf_ptr = (buf_ptr+1)%BUFLENGTH; // increment buffer index
return;
}
int main(void)
{
L138_initialise_intr(FS_48000_HZ,ADC_GAIN_0DB,DAC_ATTEN_0DB,LCDK_LINE_INPUT);
while(1);
}
I do a build to get the following results
