The simplest way to
evaluate LCD
modules!
The EDP-I is designed for evaluating
LCD modules without having to lay out
your own design. It provides pinouts for
the most popular modules in the industry
and an easy to use keyboard interface.
Demonstrating, comparing and
evaluating different modules has never
been easier. Just plug in a standard AT
style keyboard and the LCD module of
your choice. The built-in line editor will
give you complete control over the
display.
Contrast and backlight levels can be
controlled via the keyboard. Two user
defined screens can be stored in memory,
one of which is displayed on power up.
Supported Pinouts

Software selectable modes:
Supported pinouts are shown below. These allow
most LCD modules that use an HD44780
compatible controller to be connected directly.
Of course, non-standard pinouts can always be
wired in using ribbon cable.
