触摸屏逐渐取代键盘成为嵌入式系统常选用的人机交互工具。并以四线电阻式触摸屏和触摸屏控制器ADS7843,从系统的硬件入手,分析整个系统的硬软件原理及其实现方法,结合硬件的实现原理,阐述在W in-dow s CE系统下,触摸屏驱动的结构以及软件的实现方法。
The touch screen has gradually replaced the keyboard to become the embedded system commonly used human-computer interaction tools. And with four-wire resistive touch screen and touch-screen controller ADS7843, starting from the system hardware, hardware and software analysis of the entire system and its implementation methods, combined with the realization of the principle of the hardware, described in Winslow CE system, touch screen driver The structure and software implementation.
