CCS/TMS320C6713B: How to use file read write function in C code through CCSv 3.1

Part Number: TMS320C6713B


Tool/software: Code Composer Studio

Dear

Presently, I am working on c6713 dsk and used CCSv3.1 tool. I want to create file by fopen() function

And write data into this file. Program is compiled and run successfully, but no file is created.

I have given my program code below.

 

main()

{

                int i=0;

                int data1[20]={1,3,5,9,6,10,5,11,22,14,15,17,6,0,3,12,25,44,23,10};

                FILE *fileW;

                fileW=fopen("c:/turboc/gopalsarkar/gopal37.txt","w");

 

   for (i = 0; i < 20; i++)

   {

                fprintf(fileW,"%d ",data1[i]);

   }

                fclose(fileW);

}

 

This above code is working successfully in any other c compiler.

Kindly help me if you have any solution.

Wait for your kind reply.

    Hi Gopal,
    Other than needing to include stdio.h, your code looks fine and should work as expected. Note that there a bit more considerations when trying to use C I/O in an embedded environment than when simply building an application with Turbo C and running on your PC. Please see the below information for more details on these considerations:

    Thanks
