This course covers the 568XX 16-bit DSP NXP family

formateur
Objectives
  • The course explains how to design a 56807 based board.
  • Optimized coding examples are described.
  • A generic interrupt handler is introduced.
  • The course focuses on motor driving.
  • Practical exercices are executed on a 56807 board.

  • This course has been delivered several times to companies developing electric engines.
A lot of programming examples have been developed by ACSYS to explain how to write optimized code.
•  They have been developed with CodeWarrior compiler and are executed under CodeWarrior debugger.
A more detailed course description is available on request at training@ac6-training.com
  • Basic knowledge about signal processing and motor control.
  • Knowledge of CAN bus is recommended, see our course reference CAN bus, reference IA1 - CAN bus course

  • Theoretical course
    • PDF course material (in English) supplemented by a printed version for face-to-face courses.
    • Online courses are dispensed using the Teams video-conferencing system.
    • The trainer answers trainees' questions during the training and provide technical and pedagogical assistance.
  • 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 by quizzes offered at the end of various sections to verify that 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.
