  • MSCFileSystem (USB mass storage class)
  • SD card (for the SD card operation, sample code is available.).

The usage is very simple.

  1. Make a instance with path to the directory
  2. Check error status
  3. The file names are available as vector of strings inside of instance. 

#include "mbed.h"
#include "DirectoryList.h"

LocalFileSystem local( "local" );

int main(void)
{
    DirectoryList   dir( "/local" );

    if ( dir.error_check() )
        error( "directory could not be opened\r\n" );

    for ( int i = 0; i < dir.size(); i++ )
        printf( "%s\r\n", dir[ i ].c_str() );
