FlexRay is a serial communication technology that is used in particular for data communication in very safety-critical use areas in the automobile. LIN protocol is a serial wired communication protocol for electronic devices which consist of one master and one or more slaves, but it does support multiples slaves. The FlexRay protocol is a unique time-triggered protocol that provides options for deterministic data that arrives in a predictable time frame (down to a microsecond). CAN uses an arbitration scheme where nodes will yield to other nodes if they see a message with higher priority being sent on a bus. Now customize the name of a clipboard to store your clips. For starting or receiving data to LIN bus, LIN master uses different predefined scheduling tables and these scheduling tables have different relative timing when data send time is start. in Electronics System Design Engineering GREESHMA S CWB0913004 , FT-2013 8thModule Presentation Module code : ESE2512 Module name : Data Communication and Networks Module leader: Ms. Nireeksha Presentation on : 14/07/2014 FlexRay This procedure occurs in a Gateway which contains one FlexRay and three high-speed CAN ports.

FlexRay communication controller (CC) is the core of the FlexRay protocol specification. Some of the basic characteristics of the FlexRay protocol are synchronous and asynchronous frame transfer, guaranteed frame latency and jitter during synchronous transfer, prioritization of frames during asynchronous transfer, single or multi-master clock synchronization … The duration of a cycle is fixed when the network is designed, but is typically around 1-5 ms. 128 message buffers with max. 4.
