Available days


To provide a practical knowledge and understanding of real-time kernel usage. What are the advantages? What are the trade-offs? Learn from an experienced trainer and take home a working knowledge of FreeRTOS and the ability to use it efectively in your own embedded development project.


This 3-day training class uses hands-on exercises combined with instruction to illustrate the concepts of a real-time kernel. Examples using FreeRTOS form a series of practical coding exercises designed to bring you quickly up to speed. The concepts and commands necessary to make effective use of FreeRTOS are described through a combination of theory and ‘hands-on’ training. Learn from an experienced trainer and take home a working knowledge of FreeRTOS and the ability to use it effectively in your own embedded development project.


  • Familiarity with embedded C concepts and programming
  • Ability to develop software using C syntax
  • Ability to use basic embedded compiler and debug tools
  • Basic knowledge of embedded processor development boards

Who should attend?

People with interest in or tasked with development of a resource constrained real-time system. For example - software engineers, field engineers, (project) managers.
