嵌入式linux内核下串行驱动程序的实现

Development of serial device driver in embedded Linux

阐述了linux下驱动程序的基本概念和中断处理方法 ,以uClinux下的异步串行口为例 ,详细分析了串行驱动的实现过程 ,该方法和思路为在嵌入式linux下访问其他串行通信外设提供了很好的借鉴。

Basic concepts of device driver and Its interrupt handling in Linux are introduced.With a UARTs driver in uClinux as an example,the implementation of serial driver is detailed, which can be a good reference to other serial driver development in Linux.
