SdTerminal

Basic terminal interface for Arduino SD card logging/file management. Allows basic file management of an SD card with an Arduino through serial commands.

Commands:

For more information on a specific command, type help command-name
> - Create file if it doesn't already exist
ap - Append a line to an existing file
cd - Change present working directory
cp - Copy a file to another location
echo - Turn on or off echoing user commands
help - Provide info on commands. Can specify a specific command for help
ls - List the contents of the card. Can specify a specific dir for listing
mkdir - Make a new directory at a specific location
mv - Move or rename a file
print - Print the contents of the given file
pwd - Print the present working directory
rm - Remove a file or dir

Notes:

The returned message ? signifies the last command was invalid

// Uncomment 'USE_EXTERNAL_SD' define to use an external SD card adapter or leave
