This course is delivered in co-operation with Doulos' training partner Feabhas, who specialise in training courses for real-time embedded developers.
Learning the C programming language is one thing, but learning to use it effectively and appropriately in a real-time embedded environment is another. This course teaches the C programming language through the pragmatic use of C in a real-time environment. This is achieved through both lecture and direct hands-on experience. As part of the course, approximately 50% of the time is given over to writing code for a real target. During the week, attendees build up a complete solution to a case study that exercises all significant parts of the course.
• To provide an understanding of the essentials of the C programming language.
• To give you practical experience of writing C for real-time & embedded systems.
• To demonstrate the traps and pitfalls of the language when used in a real-time system.
• To give you the confidence to apply these new concepts to your next real-time project.
The course is designed for engineers who are embarking on a project using C for the first time. It is also suitable for those having to support a customer using C, and those requiring to be brought up to date since initially being taught at University.
