ex_fat.c file modified to create a file
PostPosted: Mon Apr 12, 2010 9:25 pm     Reply with quote
Hello,

I've taken a look at the ex_fat.c file to see if I'd be able to create a file into my SD Card using PIC18f4550. Here is my main code below:
Code:

void main()
{
   char opt_buffer[255];
   
   int i;   // pointer to the buffer

   // initialize the FAT
   //  keep in mind that this will automagically initialize the media
   i = fat_init();
   if (i)
      printf("\r\n\nERROR INITIALIZING FAT\r\n\n");
   
   *opt_buffer = "/test.txt";
   MakeFile(opt_buffer);   
}

I don't see why it's not showing the text.txt file on my SD Card. It's a 2GB microSD using SD Adaptor and it has been formatted to FAT32 with 4096 cluster sizes. I'd very much appreciate some input. Thank you.

p.s. the heading is exactly the same as the ex_fat.c file. I just changed the void main() to see if I could create a file in the SD Card.

Does anybody have an idea? I've modified to work this way:
Code:

void main()
{
char opt_buffer[255];
strcpy(opt_buffer, "test.txt");
   
fat_init();
/*char string[10], string2[10];
  strcpy (string, "Hi There");
  strcpy(string2,string);
*/
 
//*opt_buffer = "/test.txt";
MakeFile(opt_buffer);   
}

I'm guessing file should be made here....?
