Demo to read and write to both SD and USB File System
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"); ... }
