1 Introduction

Figure 1: LK202-25 Display

The LK202-25 is an intelligent alphanumeric liquid crystal display designed to decrease development

time by providing an instant solution to any project. In addition to the RS232, TTL and I2C protocols

available in the standard model, a USB communication model allow the LK202-25 to be connected to a

wide variety of host controllers. Communication speeds of up to 115.2kbps for serial protocols and

100kbps for I2C ensure lightning fast display updates.

The simple command structure permits easy software control of many settings including backlight

brightness, screen contrast, and baud rate. On board memory provides up to forty custom characters

which can be saved within the unit and recalled for start screens, bar graphs or larger numbers.

User input on the LK202-25 is available through a five by five matrix style keypad, and six general

purpose outputs provide simple switchable five volt sources. In addition, the option of a Dallas One-

Wire header provides a communication interface for up to thirty-two devices.

The versatile LK202-25, with all the features mentioned above, is available in a variety of colour, voltage,

and temperature options to suit almost any application.
