The Optrex DMC16117A LCD Module
Nearly all small alphanumeric LCD modules,
including the Optrex DMC16117A LCD module used in this lab,
are built around the Hitachi HD44780 LCD controller.
Information on this controller has been collected and is summarized
in these pages.
There are many factors to be considered when including a small
LCD in your design.
Among the first items to be considered are the size of the display,
the number of characters and the
display arrangement.
The
character set
that the module can display is also of interest.
When designing the hardware for your product you are most interested in the
electrical and timing characteristics
and the
module pinout.
A software designer would want to look at the chip
initialization sequence and
the
commands that must be sent to the display.
