I can write filename onto the hard drive now
Putting all the pieces together, I can create file now
Write file is working... That was really hard.
fix a writing file bug
Fix a bug where the data length would exceed 60 bytes (minus the header)
create, write, read, delete is completed with a minor bug(space is not recognized when reading)
fix the write command where space is ignored (the parse split the buffer by space, that is why it is ignored
Map all the hard drive operations to an ISR call, basic file function is complete. Swapping is next.
