#include<stdio.h>
#include<math.h>
int y[20];
main()
{ int m=6; /*Length of i/p samples sequence*/

} Open Code Composer Studio, make sure the DSP kit is turned on.
Use the Debug Connect menu option to open a debug connection to the DSK board
Start a new project using ‘Project-new ‘ pull down menu, save it in a
separate directory(C:\CCStudio_v3.1\myprojects) with name lconv.pjt.
Add the source files conv.c
to the project using ‘Projectadd files to project’ pull down menu.
Add the linker command file hello.cmd .
(Path: C:\CCStudio_v3.1\tutorial\dsk6713\hello1\hello.cmd)
Add the run time support library file rts6700.lib
(Path: C:\CCStudio_v3.1\c6000\cgtools\lib\rts6700.lib)
Compile the program using the ‘Project-compile’ pull down menu or by
clicking the shortcut icon on the left side of program window.
Build the program using the ‘Project-Build’ pull down menu or by
clicking the shortcut icon on the left side of program window.
Load the program(lconv.out) in program memory of DSP chip using the
‘File-load program’ pull down menu.
