3 Displaying Text
This chapter describes the various text-display commands in detail. Before issuing commands to the
GLC24064 please read sections 7.2 and 7.3.
3.1 General
Text is displayed on the GLC24064 using fonts saved in its internal flash memory. The display is supplied
with a 5x7 font installed. If this is suitable, then there is no need to install any other fonts.
3.2 Writing Text to the Display
When the display receives a character, it displays that character at the position currently defined. The next
character sent to the module then advances to the following position on the display. Characters are drawn
using the currently selected font, and only characters defined in the current font are actually processed.
Characters that are not defined by the current font are ignored, and the positioning is not advanced for the
next character.
The position where text is to be displayed is a single pixel location stored in the display’s volatile memory
and maintained internally by the display’s firmware. This position is manipulated by the commands shown
in the following section.
