This course targets the construction of robust, safe embedded systems using C. The focus is on developing robust, safe software in a concurrent, multi-threaded environment.

For each topic, the issues and consequences of a design or implementation will be explored, allowing the attendee to make reasoned choices when they are back in their work environment.

Pre-requisites:

A good knowledge of C. 

Who should attend:

This course is aimed at experienced C developers.
