formateur
Objectives
  • The course details the hardware implementation and describes the tests required to check the compliance of an equipment.
  • The communication scheme which enables both Time and event-triggered communications is explained.
  • The course focuses on error recovery mechanisms.
  • Implementation examples are described through NXP and Philips existing devices.
A Lecroy analyser is used to capture and display FlexRay traffic.
•  A lot of traces are included in the material.
A more detailed course description is available on request at training@ac6-training.com
Prerequisites
  • Experience of a digital bus is mandatory.
