6.1 Introduction
The GLK19264-7T-1U 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 ASCII formated 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.
6.1.1 Character Set
The graphic displays such as the GLK19264-7T-1U, do not have built in character sets. Instead fonts are
uploaded to the display using the commands detailed in Section 5 on page 19.
6.1.2 Control Characters
In addition to a full text set, the GLK19264-7T-1U display supports the following ASCII Control char-
acters:
0x0A Line feed / New line - when this value is not defined in the font file. This command will create a new
line on the display. If scrolling is on and the display is at the bottom of the screen, the whole screen is
scrolled up.
