Vergil Cola / SDFileSystem2

A fork of the original SDFileSystem, added only stat() for getting file information.

Dependents:   FRDM_K64F_IOT

Added code to the original SDFileSystem to export the stat() command. It would now be possible to get the FILEINFO struct of a directory entry to get information such as file size, etc.

SDFileSystem2 usage

#include "SDFileSystem.h"
SDFileSystem sd(p5,p6,p7,p8,"sd"); // mosi, miso, sck, cs 

static void cmd_ls(Stream * chp, int argc, char * argv[])
{
   DIR * dp;
   struct dirent * dirp;
   FILINFO fileInfo;
   char dirroot[256];
   
   if (argc >= 1)
       sprintf(dirroot, "/sd/%s", argv[0]);
   else
       sprintf(dirroot, "/sd");
   
   chp->printf("Listing directory [%s]\r\n", dirroot);
   
   dp = opendir(dirroot);			
   while((dirp = readdir(dp)) != NULL)
   {
       if (sd.stat(dirp->d_name, &fileInfo) == 0)
       {
           if (fileInfo.fattrib & AM_DIR )
                   chp->printf("<DIR>\t\t");
           else
                   chp->printf("%ld\t\t", fileInfo.fsize);
       }
       chp->printf("%s\r\n", dirp->d_name);
   }
   closedir(dp);
}
