Didn't you forget to add the project files, right? When I downloaded the file content was as in the picture. Couldn't I see it? Roll Eyes

Look at the picture well, the project file is the file with name “random_num.pdsprj”

Run_num.c


#include <Ran_Num.h>


void main()
{

   while(TRUE)
   {




      //TODO: User Code
   }

}

I didn't ask about the ISIS project. I meant files with source code (* .c, * .h).
