C Files for Practical Applications Using the 'C6711 DSK
This section lists C files for some practical DSP projects that are possible
using the TMS320C6711 DSP Starter Kit. We can separate the applications
discussed here into three broad categories:
signal generation
applications,
spectral analysis
applications using FFT, and
digital filtering
applications.
E.6.1
Signal Generation Applications Using the 'C6711 DSK
•
Sine wave generation using a look-up table
//Sinegen_table.c Generates a sinusoid for a look-up
table
#include <math.h>
#define table_size (short)10
//set table size
short sine_table[table_size];
//sine table array
short i;
interrupt void c_int11() //interrupt service routine
{
output_sample(sine_table[i]);//output each sine value
