AN-1128 GreenPAK LCD Driver frees microcontroller pins
In this application a GreenPAK SLG46620V is placed between the serial interface of an Arduino Mega 2560, and an LCD 2004A display. This approach now frees up 8 microcontroller pins for other uses in the design. Additionally, this circuit can be adapted to other LCD interfaces with minor changes in LCD initialization through the microcontroller.
