Course Description
Objectives
- Get an overview on Cortex-M4 architecture
- Discover the concepts of real time multitasking
- Understand Real Time constraints
- Determinism
- Preemption
- Interrupts
- Understand the FreeRTOS architecture
- Discover the various FreeRTOS services and APIs
- Learn how to develop FreeRTOS applications
- Learn how to debug FreeRTOS applications
Requirements
- Familiarity with embedded C concepts and programming
- Basic knowledge of embedded processors
Course duration
- Total: 20 hours
- 4 sessions, 5 hours each (excluding break time)
- From 40% to 50% of training time is devoted to practical activities
- Some Labs may be completed between sessions and are checked by the trainer on the next session
Target Audience
- Any embedded systems engineer or technician with the above prerequisites.
Course Environment
- Theoretical course
- PDF course material (in English).
- Course dispensed using the Teams video-conferencing system.
- The trainer answers trainees' questions during the training and provide technical and pedagogical assistance through the Teams video-conferencing system.
- Practical activities
- Practical activities represent from 40% to 50% of course duration.
- Code examples, exercises and solutions
- One Online Linux PC per trainee for the practical activities.
- The trainer has access to trainees' Online PCs for technical and pedagogical assistance.
- Eclipse environment and GCC compiler.
- QEMU Emulated board or physical board connected to the online PC (depending on the course).
- Some Labs may be completed between sessions and are checked by the trainer on the next session.
- Downloadable preconfigured virtual machine for post-course practical activities
- At the start of each session the trainer will interact with the trainees to ensure the course fits their expectations and correct if needed
Evaluation modalities
- The prerequisites indicated above are assessed before the training by the technical supervision of the trainee in his company, or by the trainee himself in the exceptional case of an individual trainee.
- Trainee progress is assessed in two different ways, depending on the course:
- For courses lending themselves to practical exercises, the results of the exercises are checked by the trainer while, if necessary, helping trainees to carry them out by providing additional details.
- Quizzes are offered at the end of sections that do not include practical exercises to verifythat the trainees have assimilated the points presented
- At the end of the training, each trainee receives a certificate attesting that they have successfully completed the course.
- In the event of a problem, discovered during the course, due to a lack of prerequisites by the trainee a different or additional training is offered to them, generally to reinforce their prerequisites,in agreement with their company manager if applicable.
