ACTIVITY #1: CONNECTING AND TESTING THE LCD
Along with the electrical connections and some simple PBASIC test programs for the
Parallax Serial LCD, this activity introduces the
how
your serial LCD because you can take many of the
them with the
displays.
Parts Required
(1) Parallax 2×16 Serial LCD
(3) Jumper wires
In addition to the Parallax Serial LCD and three wires, it will be especially important to
have the Parallax Serial LCD Documentation (included as Appendix B in this text).
Although it's only a few pages, it has a long list of values you can send to your LCD to
make it perform functions similar to those you've used with the Debug Terminal. Cursor
control, carriage returns, clear screen and so on, all have their own special codes. In
some cases, these codes are identical to the ones for the Debug Terminal; in other cases,
they are quite different.
Building the Serial LCD Circuit
Connecting the Parallax Serial LCD to the BASIC Stamp is amazingly simple, as shown
in Figure 1-4. You only need to make three connections: one for power, one for ground,
and one for signal. The LCD's RX pin is for the signal and should be connected to a
BASIC Stamp I/O pin. In this activity, we will use P14. The LCD's GND pin should be
connected to Vss on the Board of Education, and the LCD's 5 V pin should be connected
to Vdd.
DEBUG
CAUTIONS: Wiring mistakes can damage this LCD.
Rev D and earlier models if this LCD had five pins. If you have a 5-pin model, please
see Figure B-1 on page 306 to verify the correct pins to use in the circuits in this
book.
The five-pin version is NOT pin compatible with Scott Edwards or Matrix Orbital
models. If you have used other brands of serial LCDs before, be aware that this LCD's
pinout is different. Don't make the mistake of using the same wiring that you used for other
models.
is just a special case of
