Example (more detailed example in the main.cpp file):
#include "mbed.h"
#include "MSCFileSystem.h"
#include "SDFileSystem.h"
MSCFileSystem fs("fs");
SDFileSystem sd(p5, p6, p7, p8, "sd", p11, SDFileSystem::SWITCH_NEG_NO, 15000000);
// CAUTION: Return values should ALWAYS be checked. Not shown here for brevity.
int main() {
...
FileHandle * sdfile = sd.open("test.txt", O_WRONLY | O_CREAT | O_TRUNC);
sdfile->write("hello", 6);
sdfile->close();
...
FILE * file = fopen("nextest.txt", "w");
fwrite(buffer, 1, sizeof(buffer), file);
fclose(file);
...
mkdir("/sd/sd_dir", 0777);
mkdir("/fs/fs_dir", 0777);
remove("/sd/sdfinal.log");
rename("/sd/sdfinal.txt", "/sd/sdfinal.log");
...
