Course Description
The VxWorks® Intermediate Application Development Use Cases course provides engineers with a solid grounding in a selection of the more sophisticated APIs provided in VxWorks.
Course Results
After this course, participants will be able to perform the following:
- Effectively use two different signal interfaces to deal with synchronous events
- Leverage semaphores, message queues, and events to support applications with complex interactions
- Use three VxWorks-specific printing APIs that provide greater capability and flexibility than printf
- Use VxWorks APIs to map physical memory to the virtual address space of a real-time process
- Create and use shared libraries to decrease memory footprint of applications
Products Supported
- Wind River® VxWorks 6.9
- Wind River Workbench 3.3
- Wind River Simics 4.6
Who Should Attend
- Software developers needing to implement synchronous behavior in an application
- Engineers needing to provide graceful exception-handling capabilities to application developers
- Software developers needing to understand how to use VxWorks kernel calls in a complex application
- Software developers needing a variety of simple debug tools akin to printf but with greater capability
- Engineers required to provide device driver support within the context of a real-time process
- Software developers needing to share code between applications running in multiple real-time processes
Course Format
- One day of hands-on use cases covering five topics, with technical assistance and individual guidance available from an expert instructor
- Use of VxWorks 6.9, Workbench 3.3, and Simics 4.6 to gain experience with the topics presented
