NRF5nRF Connect SDK Programming
From Theory to Practice
Objectifs
  • Apprendre à développer, configurer, déboguer et tracer des applications Zephyr
  • Découvrir le concept de multitâche temps réel
  • Comprendre les contraintes temps réel, comme le déterminisme, la préemption ou les interruptions
  • Comprendre les services du kernel Zephyr
  • Apprendre les mécanismes de communication et de synchronisation
  • Comprendre la gestion de la mémoire et les structures de données de Zephyr
  • Comprendre le mode utilisateur et le mode kernel
  • Écrire un device tree
  • Écrire un pilote complet
  • Cours théorique
    • Support de cours imprimé et au format PDF (en anglais)
    • Le formateur répond aux questions des stagiaires en direct pendant la formation et fournit une assistance technique et pédagogique
  • Activités pratiques
    • Les activités pratiques représentent de 40% à 50% de la durée du cours
    • Elles permettent de valider ou compléter les connaissances acquises pendant le cours théorique.
    • Une machine virtuelle préconfigurée
    • Cible Qemu
    • Exemples de code, exercices et solutions
    • Le formateur assiste les stagiaires pendant les exercices
  • Au début de chaque demi-journée une période est réservée à une interaction avec les stagiaires pour s'assurer que le cours répond à leurs attentes et l'adapter si nécessaire
  • Durée totale : 5 jours
  • De 40% à 50% du temps de formation est consacré aux activités pratiques qui servent à valider la bonne compréhension des concepts enseignés.
  • 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
  • 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.
