摘要
Linux因其完全开放的特性和稳定优良的性能深受欢迎,当推出了内核输入子系统后,更方便了嵌入式领域的驱动开放。介绍了Linux的设备驱动基础,详细阐述了基于Linux内核输入子系统下的设备驱动实现流程和构架。并以触摸屏为例,对驱动过程进行了分析研究。利用输入子系统的接口函数,将更方便的实现设备驱动。
Linux is popular with its complete open characteristic and fine performance. After issuing its kernel subsystem, it makes more benefits for driver design in embedded area. The foundation of the device driver with Linux is introduced and detailed expatiates how to process the device driver based of the Linux kernel subsystem. Exampling of the touch screen, the paper analyzes and studies the driver processing. Using the input subsystem interface function, we will be more convenient to realize the device driver.
