Clear the screen.
Show the contents of the current directory.
Make “dirname”directory. If “dirname” is incorrect or already exists, an error message is
returned.
Change to “dirname” directory. If “dirname” is incorrect or does not exist in the present
directory, an error message is returned.
Remove “dirname” directory. If “dirname” is incorrect, an error message is returned.
IMPORTANT: No check is done on “dirname” directory contents before removal.
Show the ASCII contents of a file in the current directory.
Delete a file in the current directory.
Format the existing FAT16 partition. Note: This will not work properly if the existing file
system is of a format other than FAT16. See “Appendix B—Formatting a Memory Card”
for instructions on how to format a new disk.
Show the contents of the nnnnn-th 512-byte block. Calling “S” without a parameter will
print the valid range of sectors.
Show info about the formatting used.
Sets offset for temperature sensor. ‘val’ should be current ambient temperature in
degrees C.
the specified file in the current directory. Calling “TEMPLOG” without a parameter will
stop current logging, if any, and close that file.
Start background logging of the state of the two buttons (P2.1 and P2.2). The logging is
appended at the end of the specified file in the current directory. Calling “LOG” without a
parameter will stop current logging, if any, and close that file.
