摘要：为了简化传统Linux驱动程序设计及便于对驱动模块的管理与维护,采用了基于内核对象的输入子系统，完成了Linux设备驱动框架，改进了传统基于文件操作接口的驱动程序设计方法，提出了只需向系统报告输入事件的开发方法，并顺利地实现了触摸驱动的开发。试验结果表明，该驱动运行稳定并能精确控制触摸屏。

Abstract: Aiming at simplifying the design of traditional Linux driver and contributing to management and maintenance of the drive model, using the input subsystem based on kernel object, the Linux device drivers framework was fulfilled. The traditional method concerned with the interfaces of file operations was improved. The method of only reporting the input event to the Linux system was proposed. The driver was successfully developed. The test results indicate that the driver works well, and it can control the touch screen precisely.
