基于S3C44B0X的触摸屏驱动程序的设计
摘 要
随着电子设备的不断智能化,传统的键盘、鼠标等人机交互方式已经无法满足人们的需求,人们想要更加方便准确的人机交互工具。而触摸屏通过手指触摸就能实现操作定位,大大简化了电子设备的输入方式,真正实现零距离操作,因此触摸屏得到了越来越广泛的应用。
本文介绍了基于ARM7TDMI内核的高性能微处理器S3C44B0X的基本功能,阐述了触摸屏的组成与基本工作原理,并在分析触摸屏嵌入式系统的基础上,针对触摸屏驱动控制程序的难点,提出了具体的解决方案,最终完成了基于微处理器S3C44B0X的触摸屏驱动控制程序的设计。

Driven design of touch screen based on
S3C44B0X
Abstract
With the intelligent electronic devices, Traditional keyboard, mouse and other human-computer interaction has been unable to meet people's needs,People want to have more convenient and accurate human-computer interaction tool. And touch screen can be realized positioning operation by fingers touch,This greatly simplifying the input mode of the electronic equipment and realizing zero distance operation, so the touch screen has been more and more widely used.
This article describes the basic functions of high-performance microprocessor S3C44B0X based on the ARM7TDMI core, Describes the composition and the basic working principle of the touch screen.For the the drive control program’s difficulties of touch screen,I proposed the specific solutions based on the analysis of the
touch-screen embedded system .Finally,I completed the touch screen’s driver control
program design based on S3C44B0X.
