8x2 Character LCD - Black Bezel Parallel Interface
This little 8-character, 2-line parallel liquid crystal display is a generic equivalent of the Optrex DMC-50448N-AAE-AD LCD.
It is incorporated into our Orangutan, Orangutan LV-168, and Orangutan SV-328 robot controllers and 3pi robot.
It uses the common HD44780 interface, so sample interface code is widely available for a variety of microcontrollers.
This is the smallest package we know of for this familiar interface.
You can find sample HD44780 LCD interface code written for a variety of AVR microcontrollers as part of the Pololu AVR library.
