RT7Real Time Programming with RT-Thread
From Theory to Practice
|
Objectives
|
- Theoretical course
- PDF course material (in English) supplemented by a printed version.
- The trainer answers trainees' questions during the training and provide technical and pedagogical assistance.
- Practical activities
- Practical activities represent from 40% to 50% of course duration.
- Code examples, exercises and solutions
- One PC (Linux ou Windows) for the practical activities with, if appropriate, a target board.
- One PC for two trainees when there are more than 6 trainees.
- For onsite trainings:
- An installation and test manual is provided to allow preinstallation of the needed software.
- The trainer come with target boards if needed during the practical activities (and bring them back at the end of the course).
- 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
- Strong embedded C programming skills
- Basic knowledge of embedded processors
- 3 days
- Any embedded systems engineer or technician with the above prerequisites.
- The prerequisites indicated above are assessed before the training by the technical supervision of the traineein 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.
