freeRTOS in Theory and Practice
Date: 03. - 05.07.2018| 3 days, 9.00 - 17.00
Training Fee: 1.790 Euro plus VAT tax
Training Description: PDF
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 effectively 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.

Method and Training Materials
Presentation and practical examples with host (Laptops with Ubuntu 14.04.x LTS) and target system
(e.g.Beagle Bone Black Rev. C - http://beagleboard.org/BLACK)
The electronic devices will be provided during the training. There will be one workspace for two participants.
A customized version of this training like FreeRTOS on LPCXPresso 1769 is offered by FreeRTOS.
