A UNIX emulation shell to access the underlying SDCard FileSystem through a terminal interface
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");
}
