This serie of pages on this website will help you on your way with the Parallax (OEM) Basic Stamp II microcontroller.

Controlling a Hitachi 44780 based LCD display.

Tip: for Mitsubishi 50530 based displays, read the Optrex 50652N article.

In this article I'll try to explain to you how to control a LCD display with your (OEM) Basic Stamp II using an old LCD panel from an Ericsson DBC661 phone or any 44780 based LCD for that matter. For control using a PC see the LCD Project page.

The LCD panels I used are the OPTREX DMC2034 and DMC50400 which I got out two defect Ericsson phones. These are 4 x 20 (4 lines, 20 characters) panels.
