2.4 The Built-In Character Font

The LK202-24-USB includes a built-in 5 x 7 dot matrix font with the full range of ASCII characters plus a

variety of extended characters, as shown in Figure 2-5.

Figure 2-5 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 LK202-24-USB does not have provision to

download other fonts.

2.5 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).
