See Also SetFont
Purpose To select a font size for the LCD to display alphanumeric characters properly.
Syntax void SetFont (int font);
int font;
Example SetFont (FONT_8X16);
Description This routine specifies what size of font is to be used following this call.
The value of the parameter font depends on the current font and its available
font size options. It can be one of the following:
FONT_6X8
FONT_8X16
FONT_6X12
FONT_12X12
Single-byte Characters:
For single-byte characters (system, multilanguage, etc.), simply assign
either FONT6X8 or FONT_8X16.
16x16 Double-byte Characters:
You may assign FONT_6X8 or FONT_8X16 to display alphanumeric
characters.
12x12 Double-byte Characters:
If you assign FONT_6X12, the font size for single byte characters will be
6x12, while it will still take 12x12 for double-byte characters (Tc12, Sc12,
Jp12). It thus provides flexibility in displaying alphanumeric.
However, for Japanese Katakana, you have to assign FONT_12X12;
otherwise, the cursor position will be misplaced.
