There are lots of examples in the cook book,


  1. include "mbed.h"

LocalFileSystem local("local"); Create the local filesystem under the name "local"

int main() { FILE *fp = fopen("/local/out.txt", "w"); Open "out.txt" on the local file system for writing fprintf(fp, "Hello World!"); fclose(fp); }


there should be quite a few examples out there.

don't forget, more info more help.


Thanks Ceri, seen that and actually got what i want. this keeps overwriting in a continuous loop but opening a log file did the job

what should I do if I have to assign a saved integer value in sd card to a variable in the code. I have to increment and save it after signal stops coming in.
