基于嵌入式Linux的字符设备驱动开发

Development of characters device drives based on embedded Linux

设备驱动程序是Linux内核的重要组成部分,它控制了操作系统和硬件设备之间的交互,同时让软件开发人员在不用知道底层硬件特性的情况下方便地进行上层软件的开发。基于Arm+Linux系统,内核版本2.6,对字符驱动程序的开发做出详细的讲解,通过调试程序,使驱动正常运行。

The device drivers are an important component of the Linux kernel. It controls the interaction between the operating system and the hardware and allows the software developers to facilitate the development of the top software without knowing the underlying hardware characteristics. A detailed presentation of the device drivers development is made and through the debug the drive works well.
