| Abstract: | In this paper we analyse deeply the CAN bus's communication mechanism with regard to the arbitration,acknowledge and message filtering based on the hardware principle model of CAN,bring forward a simplified hardware circuit design for CAN bus.Taking this as the basis,after having researched on and analysed the encapsulating method of low level drivers of MCF52235's FlexCAN module which belongs to Freescale corporation,in this article we give the FlexCAN component design which meets the transplantation and r... |
