Design and Construction of Message Display System Using PIC Microcontroller

Abstract

This paper is intended to design and display message on Liquid Crystal Display (LCD) using PIC microcontroller. PIC (Peripheral Interface Controller), a special type of microprocessor is used to control the LCD (Liquid Crystal Display) and the related circuit. The proposed message displayed system is based on microcontroller, digital logic circuitry, programming, as well as the LCD display and other necessary power delivery. In this paper, the message display system which is based on PIC microcontroller is intended to use for advertising on a billboard. The design of the system is simple but it used efficient technology for cost effectiveness. The message can also be displayed occasionally for special purpose via personal computer. By storing the desired characters message inside the storage of PIC, i.e. EEPROM, ROM, and other external flash memories, the stored message can be displayed. The control program for displaying message is written by Assembly Language and the code is changed into Hex format by using MPLAB 7.20 software and then Hex codes are placed into PIC with the help of EPIC Win software. The proposed microcontroller-based control system can give accuracy, efficient time response and flexibility. The main contribution of this paper is to implement a PIC based displayed system for desired short message as an information system in Myanmar.
