5.1 Introduction
The LK204-25 is an intelligent display module, designed to reduce the amount of code necessary to
begin displaying data. This means that it is able to display all characters and strings that are sent to it, which
are defined in the current character set. The display module will begin displaying text at the top left corner
of the display area, known as home, and continue to print to the display as if it was a page on a typewriter.
When the text reaches the bottom right row, it is able to automatically scroll all of the lines up and continue
to display text, with the auto scroll option set to on.
