Connect the LCD to Parallel Port A.
The R/W pin and DB0–DB3 on
the LCD are grounded. DB0–DB3
are not used with a 4-bit interface.
This sample program only involves writing, and that is why we ground the R/W pin.
VEE is used to control brightness—the simplest thing to do is ground it. If you need to
control the brightness, you can connect a potentiometer between ground and -5 V, with
the arm going to the VEE pin. Check the specs on the LCD before doing this as some
LCDs may require a different connection. VCC is +5 V and VSS is ground.
