In case you want to train multiple members of your team you might also want to query for an on-site training. Ask for multi-enrollment discounts.

Description

This 3-day training class uses hands-on exercises combined with instruction to illustrate the concepts of a real-time operating system. FreeRTOS will be used as an example. It is 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 on-the-job training. Don’t reinvent the wheel, but 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.
