Note about the extra 220 Ohm resistors for the LCD display
----------------------------------------------------------
Some LCD controller chips have a higher capacity on their input
lines than others. A higher input capacity can possibly have a negative
impact on the signals during program load into the microcontroller.
You will need these resistors if you experience that the program does
not load at all or it does not run after loading even though there
is no fault in the software.

The displays from tuxgraphics have the following requirements:
- 16x2 character display => needs the two resistors
- 20x2 character display => resistors are not needed but it does
                            not harm if you have them in the circuit.
