16x2 Character LCD (Parallel Interface)

This 16-character, 2-line parallel liquid crystal display achieves a large viewing area in a compact package. It uses the common HD44780 interface (330k pdf), so sample interface code is widely available for a variety of microcontrollers. This LCD is also available with a backlight.

The DDRAM address 0x00 corresponds to the first character of the top line, address 0x0F corresponds to the last character of the top line, address 0x40 corresponds to the first character of the second line, and address 0x4F corresponds to the last character of the second line.

You can find sample HD44780 LCD interface code written for Atmel’s ATmega644 AVR microcontroller on our Orangutan X2’s resources page. Sample code for other AVRs (e.g. ATmega168, ATmega328, ATmega324, and ATmega1284) can be found as part of the open-source Orangutan-lib package, or on our Orangutan LV-168’s resources page
