CODE:
Mounting an SD card:
sd_result = f_mount(&sdCard,SDPath, 1);

Opening a file:
sd_result = f_open(&testFile ,(void*)file_name, FA_WRITE|FA_CREATE_ALWAYS);

Writing to the file:
sd_result = f_write(&testFile,(void *)test_text, (UINT)sizeof(test_text), (UINT*)&temp_number);

Closing the file:
f_close(&testFile);
