Abstract

This paper analyzes the way Liquid Crystal Display (LCD) is interfaced to a microcontroller for information display in real-time systems. To achieve this purpose, a background study of LCD and microcontroller was x-rayed. The LM016L type of LCD (an alphanumeric LCD) was used as a case study of the LCD for the analysis, while AT89C51 microcontroller was used as a case study of the microcontroller analyzed. It was seen that by programming a microcontroller adequately to execute LCD Command and Data write codes, information (alphabets and numbers) could be displayed on the LCD. The interface program was developed in Assembly language, and the output of the interface was displayed in a Proteus environment.
