VxWorks 6.x Device Drivers
Acquire the skills necessary to develop device drivers using both legacy VxWorks and VxBus device driver models.
Course Description
The VxWorks® 6.x Device Drivers workshop provides engineers with an efficient way to acquire the skills necessary to develop device drivers using both legacy VxWorks and VxBus device driver models.
Course Results
After this course, participants will be able to perform the following:
- Optimize the development of a new device driver from scratch
- Use coding conventions for ease of debugging and driver portability
- Utilize common techniques for driver development
- Write standard VxWorks I/O drivers
- Distinguish between legacy VxWorks and VxBus drivers and determine which driver model is appropriate for a particular application
- Design and integrate custom VxBus drivers
- Migrate proprietary and legacy drivers to VxBus
Products Supported
- VxWorks 6.8
- Wind River® Workbench 3.2
Who Should Attend
- Developers with general experience writing device drivers for embedded hardware systems
- Engineers who will develop VxBus-enabled device drivers
Course Format
- This four-day expert-led course consists of lectures and lab sessions.
- Attendees use VxWorks 6.8 and Wind River Workbench 3.2 to gain experience with the topics presented.
- Participants examine and exercise simulated network topologies in hands-on labs.
- Participants receive individual guidance from an expert engineer who has extensive experience with Wind River technologies.
