Connecting a LCD display to your personal
computer is an easy job. Displaying data from your PC to a LCD can be
proven very exiting, so give it a try and build
your own today!
In this article we will use a 2 lines x 16
characters LCD display with
Hitachi
HD44780 onboard
controller. You can use any size of LCD like 1x16, 2x40, 4x20 e.t.c but
keep in mind that it must have
HD44780
or
or
compatible
controller which is the most popular at this kind of LCD displays.
We will use a free printer port (LPT) for
communication between LCD module and PC. For this interconnection we only
need 10 wires between LCD and LPT and two additional wires for power.
To control the LCD there
are some free programs that can do that job very well and providing many
capabilities. We will discover them later.
