RT2MQX Real Time Programming
Real-time programming applied to the MQX operating system
Objectives
  • Discover the concepts of real time multitasking
  • Understand Real Time constraints
    • Determinism
    • Preemption
    • Interrupts
  • Understand the MQX architecture
  • Discover the various MQX services and APIs
  • Learn how to develop MQX applications
  • Learn how to debug MQX applications
  • Learn how to use MQX Library (USB, TCP/IP, File System, Embedded GUI)
  • Get an overview on Cortex-M4 architecture
  • Convenient course material with space for taking notes
  • Example code, labs and solutions
  • A PC under Windows XP for two trainees
  • A NXP Kinetis K60 (Cortex/M4) with CodeWarrior IDE
  • Familiarity with embedded C concepts and programming
  • Basic knowledge of embedded processors
  • 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.
