摘 要本文在单片机开发技术的基础上进行系统的分析与设计，首先在绪论中介绍了系统的开发背景和意义，软件和硬件的开发平台。系统采用了四线电阻触摸屏作为输入设备，240×128液晶显示器作为输出设备，达到以触摸的形式实现人机交互的目的。触摸屏是近年来比较先友圆塌进的输入设备，在多媒体信息查询中得到了广泛的应用。本好圆文着重论述硬件结构设计、对触摸屏技术及触摸屏控制器ADS7846、T6963C液晶控制器等器件做了详细的介绍，并结合课题剖析了软件设计和开发的过程腔空，及其是主程序与中断子程序的设计概念。关键词 单片机；触摸屏；ADS7846芯片AbstractThis text carries on systematic analysis and design on the basis of the one-chip computer develops technology, have introduced systematic development background and meaning, the developing platforms of the software and hardware in the introduction at first.The system has adopted the 4-wire resistance touch screen of the resistance as the input equipment, 240×128 liquid crystal displays are regarded as the output equipment, achieve it with the purpose of realizing human-computer interaction form touching.The touch screen is more advanced input equipment in recent years, widely used in the information inquiry of the multimedia. This text describes the structural design of the hardware emphatically, have done the detailed introduction to the devices , such as technology and touch- sensitive screen controller ADS7846 , T6963C liquid crystal controller etc., and the course of combining the subject and analyzing software design and developing , and design concept of the main program and interruption the subprogram.Keywords One-chip computer Touch screen ADS7846 chip目 录摘 要............................................................
