need help using C6713 with CCS5

Hi,

I am new to embedded programming and I need to learn how to program the TI C6713 board. Since it is 2012, I am working on Windows 7 and using the latest CCS (5.2.1.00018) instead of CCS 3.1 for Windows XP that came with the kit from Spectrum Digital some years ago.

Will you recommend how I can get started? After watching the 'getting started' video, I have no trouble creating a new project, compiling, and running something that merely prints 'Hello World'. Now, how do I move beyond a program with only a print statement? I mention my attempt below.

With the CCS 3.1 installation there exist many tutorials and example code for the C6713 board. I tried importing one of those projects. The import wizard had an options for "Legacy CCS 3.3 Projects", and I tried it despite having a CCS 3.1 project. I imported a project found under "C:\CCS_v3.1/tutorial/dsk6713/gelsolid" called 'hellodsp' . I have shown the compile errors below.

After import, several .cmd and .gel files are visible in the project. I do not know how to compose these files myself, or if they are relevant to CCS 5.2.

On a 2nd attempt, I imported a project called 'sinewave' and this had no compile errors. I was able to run it with the debugger. I saw the board's 'busy' LED change. I'm not sure if the source does anything useful, like plotting a graph for me to get confirmation that the board is crunching some numbers. I've copied the source code below.

// ****************************************************************
// Description: This application uses Probe Points to obtain input
// (a sine wave). It then takes this signal, and applies a gain
// factor to it.
// Filename: Sine.c
// ****************************************************************

#include <stdio.h>
// define boolean TRUE
#ifndef TRUE
#define TRUE 1
#endif

// buffer constants
#define BUFFSIZE 0x64
#define INITIALGAIN 5

// IO buffer structure
typedef struct IOBuffer {                
    int input[BUFFSIZE];             
    int output[BUFFSIZE];    
} BufferContents;

      
// gain control variable
int gain = INITIALGAIN;   

// declare and initalize a IO buffer       
BufferContents currentBuffer;

// Define some functions
static void processing();                        // process the input and generate output
static void dataIO();                            // dummy function to be used with ProbePoint

void main()
{
    puts("SineWave example started.\n");
            
    while(TRUE) // loop forever
    {       
        /*  Read input data using a probe-point connected to a host file.
            Write output data to a graph connected through a probe-point. */
        dataIO();
        
        /* Apply the gain to the input to obtain the output */
        processing();
    }
}

/*
 * FUNCTION:        Apply signal processing transform to input signal
 *                     to generate output signal
 * PARAMETERS:         BufferContents struct containing input/output arrays of size BUFFSIZE
 * RETURN VALUE:     none.
 */
static void processing()
{
    int size = BUFFSIZE;

    while(size--){
        currentBuffer.output[size] = currentBuffer.input[size] * gain;    // apply gain to input
    }
}

/*
 * FUNCTION:         Read input signal and write processed output signal
 *                    using ProbePoints
 * PARAMETERS: none.
 * RETURN VALUE: none.
 */
static void dataIO()
{
    /* do data I/O */
    return;
}

If I read CCS 5.2 user guide, will this help me toward my goal of using the C6713 board?

Also, how do I know if the C6713 is a 'single core DSP' or a 'multi core DSP' ? Am I in the right forum?

Thank you for any suggestions,

John
