Device Driver And Network Communications Under Embedded System VxWorks

As Embedded system are the most popular technology applied in war industry, information appliances, it has become an important technology how to design the device drivers and implement network communicatioans and management under an embedded system. This paper accomplishes the designing of the device driver under VxWorks system, and the designing of the network communications and network management.The paper is devided into following three points:Firstly, the development of device drivers under VxWorks system. It has finished the drivers of the project's cards. It can read and write from I/O and double port RAM, and control the interrupt service routine with signals.Secondly, the implementation of network communications under the VxWorks system is discussed. The model of client/serve is established by the TCP/IP protocol and socket. Zipped or unzipped, data are transmitted between the host and the target through the network.Finally, the fulfillment of network management based on GUI is dealt with. The program implements four function modules, including the MIB browser, the configure management, the trouble management and the performance management, all of which are added with graphical user interfaces (GUI) with the association of WINDML and ZINC.
