Applied Research of FlexRay node based on DSP

FlexRay bus and node composition are introduced.And digital processor DSP TMS320 F2812 as the host processor is connected with Freescale's communication controller MFR4300 to constitute a FlexRay network nodes to achieve the physical transport layer.FlexRay protocol and working mechanism are described.Node re-ceiving or transmitting data capabilities are achieved after chip initialization,configuration of sending/receiving state,and communications program compilation.
