摘　　要：Linux是目前最为优秀的开源系统软件之一,其完全开放的特性和优良的性能表现使其在程序开发领域广受欢迎,而其不断完善的功能和极好的适应性更使其成为嵌入式领域的首选。根据应用的需要Linux推出了内核输入子系统的开发平台,极大地方便了嵌入式领域的驱动开发。触摸屏是较常使用的外部输入设备之一,尤其是在嵌入式领域里得到了广泛的应用。文中分析了在Linux 2.6内核输入子系统下触摸屏驱动程序设计,并对比传统的驱动设计方法;得出了基于Linux输入子系统的驱动程序设计优点。Linux is one of the most excellent open source system software, it is widely popular because of its complete open cbaraeteristie and fine performance, its continually improved functions and good flexibility make it be the preferred program in the embedded area. According with the development of application, Linux issues its kernel input sub-system, it makes most benefits for driver design in embedded area. Touch screen is one of the most normal input devices,and it is especially important in embedded area. By analyzing a touch screen driver program under Linux-2.6 input sub-system and comparing it to the normal driver program design way,show the advan-tages of Linux sub-system.
