基于Vxworks嵌入式系统的多串口扩展卡设备驱动程序设计

The Design of Device Driver for Multi-serial Card Based on Vxworks Embedded System

本文分析Vxworks操作系统下设备驱动程序在系统中的层次结构和串口设备驱动程序的运行机制,并结合对多串口卡的驱动程序介绍了串口设备驱动程序开发的基本思路.

The paper analyzes the hierarchy of the device driver in the Vxworks system and the running mechanism of the device driver for the serials, and introduces the basic idea of the development of the device driver for the serials based on the design of the device driver for multi-serial card.
