The Hitachi HD44780 Character LCD Controller is commonly used on character
|
||||
LCDs that can display one or more lines of text. It exposes an M6800 bus
|
||||
interface, which can be used in either 4-bit or 8-bit mode. By using a
|
||||
GPIO expander it is possible to use the driver with one of the popular I2C
|
||||
expander boards based on the PCF8574 available for these displays. For
|
||||
an example see below.
