Interface to Liquid Crystal Display
Character Font and Number of Lines: The HD44780U can perform two types of displays, 5
× 8 dot and
5
× 10 dot character fonts, each with a cursor.
Up to two lines are displayed for 5
× 8 dots and one line for 5 × 10 dots. Therefore, a total of three
types of common signals are available (Table 9).
The number of lines and font types can be selected by the program. (See Table 6, Instructions.)
Connection to HD44780 and Liquid Crystal Display: See Figure 19 for the connection examples.
