Sam Grove / SDShell

A UNIX emulation shell to access the underlying SDCard FileSystem through a terminal interface

Dependents:   Waldo_Embed_V2

Information

Dependencies not included with library:

Information

SDShell does not change the com baudrate. Access is made using the baud as initialized by the Serial object when passed into the SDShell object

Example

#include "mbed.h"
#include "SDFileSystem.h"
#include "SDShell.h"

Serial com(USBTX, USBRX);
SDFileSystem sd(p11, p12, p13, p14, "sd");
SDShell emulate;

int main()
{
    emulate.init();
    emulate.shell(com, sd, "/sd");
}
