| IA2 | FlexRay 2.1 |
| 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 Freescale and Philips existing devices. | ||
| A Lecroy analyser is used to capture and display FlexRay traffic. •A lot of traces are included in the material. |
