Figure 14: Character Set

In addition to the built in characters, users may define up to 8 special characters which once defined,

occupy positions 0x00 to 0x07 in the above chart. The display does not have provision to download other

fonts.

3.3 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 built in font, and only characters defined in the font are actually displayed. Characters that

are not defined by the built in font print as a space (i.e., the cursor is advanced for the next character).

The position where text is to be inserted is a character 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.
