Multi-byte Commands To Arduino #15

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Add to the Arduino command interpreter to read into a buffer until it
receives a \n char. 

This will allow for more advanced commands like 'leftWheel=100' and a
configuration command.

They can be up to 20 characters long (configurable) but must end with a ';' or 
a '\n'.

The new code is non-blocking so you can send half a command and the robot will
continue to loop the loop() and it will remember the first half of the command 
when
you send the rest and proceed to parse it.

I had to modify the Android code to append a ';' char to the end of each 
command as
the Arduino doesnt seem to get the \n char from the android.

If using the Arduino serial monitor, remember to add the ';' to the end of each
command as it doesn't send a \n.
