Programming in the Osek/Vdx Environment

Use the OSEK/VDX open standard to achieve efficiencies in programming your communications and control systems. This tutorial presents each element of the standard - operating system (OS), communication (COM), and network management (NM) - independently so you can refer to the sections pertinent to your project. The presentation features an example application that demonstrates all aspects of the API without focusing on the standard's automotive origins.

Developing an application using OSEK/VDX used to mean wading through 500 pages of official standards documentation to discover what the system did, followed by a period of experimentation to discover how it could best be used. Joe Lemieux has set out change all that, writing a book designed for application developers. Progressively introducing all the major concepts of the operating system, communications module and network management facilities through the book, the reader learns about the facilities available and, most importantly, how they can be used in the real world. An example program based on a card game illustrates each new feature or service as it is explained without the reader requiring specialist knowledge of particular automotive applications. With plenty of examples and exercises,this book provides an accessible entry in to the world of OSEK/VDX.
