Abstract: Today, great research efforts have been paid to the embedded devices which are employed in many fields including communication, automation engineering, and so on. As one of the RTOS (Real-Time Operating System) for developing embedded devices, VxWorks becomes very popular. In applying VxWorks in engineering area, the main difficulty that programmers are often confronted with is the development of efficient and reliable device drivers. This paper presents in detail the primary aspects in this regard. It will provide a useful reference for VxWorks beginners.
