摘要
提出了一种用8位单片机控制16位带触摸屏的LCD的设计方法。TFT-LCD模块T32QM6450是一种点阵型LCD,文中介绍了该模块以及触摸屏控制器ADS7843的基本功能和工作原理。给出了W77E58、T32QM6450及ADS7843之间的接口设计方法,研究了实现字符、汉字、画面显示及屏幕滚动的编程方法,并给出了实现部分功能的通用子程序。
This paper presented a method that using a 8 bit MCU for the control of LCD with touch-screen. T32QM6450, a TFT-LCD module is a dot matrix LCD module. The paper introduced the basic function and operational principle of T32QM6450 and ADS7843 ;described the interface among W77E58 ,T32QM6450 and ADS7843 ;studied the method to display characters,words and graphs and demonstrated relative sub-programs to realize some common functions.
