摘要
结合嵌入式开发板S3C2410的GPIO驱动程序的开发,对L inux字符设备驱动程序的组成、实现、调试和发布方法进行了详细地论述。开发嵌入式Linux下的设备驱动程序,可以更好地利用新硬件特性,提高系统访问硬件的效率,提供更多的功能。
The components, implementation and debugging of Linux character device drivers are discussed in detail combining with the development of GPIO driver on the S3C2410 embedded development board. Thus, we can take better advantage of new hardware features, improve the efficiency of accessing the hardware system and provide more functionality.
