单片机控制液晶屏接口电路的设计与实现

Design and Implement of LCD Control Interface Circuit Based on Single-chip Computer

介绍了HD 44780型LCD液晶显示模块控制器及工作原理,用AT89S51单片机实现LCD控制电路,源程序用C语言编程,最终实现了液晶屏界面的中英文及点阵画面的静态和动态显示.

The LCD controller HD44780 and its principle was introduced.The circuit controlled by using a single-chip computer,the source program written by using C language,and ultimately the static and dynamic Chinese and English character and picture was displayed on the LCD.
