Abstract

Presently,the development of embedded systems need the support of operating systems.It is one of the most necessary works to develop hardware device drivers based on embedded operating system.VxWorks of Co.WindRiver is a real-time embedded operating system(RTOS).This paper introduces a design of serial device driver based on VxWorks,and discusses the design of serial device driver upon ST16C554 specially.Some important codes of the driver program are offered.The methods introduced here comply the principle of device drivers in VxWorks and are significative to other device drivers based on VxWorks.
