嵌入式VxWorks的多串口共享中断的驱动程序设计

The Design of Driver for Multi Serial Sharing IRQ Based on VxWorks System

该文介绍了嵌入式VxWorks操作系统的串行设备驱动程序的结构,分析了VxWorks启动过程中串行设备驱动的实现,设计了一个基于VxWorks操作系统的多串口共享中断的驱动程序,并且实现了将串口驱动程序以模块的方式动态加载到VxWorks操作系统中。

This paper introduces the structure of serial port driver on the VxWorks system, then the achievement of the driver of serial driver is analyzed. The driver for multi serial sharing IRQ based on VxWorks system is designed, and loading VxWorks system with the module of the driver is achieved.
