【摘要】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 reusability requirements in accordance with the principles of embedded software engineering, and provide the technical support to improving the development efficiency for similar applications and enhancing the system stability.In this paper we also offer the implementation ways of establishing CAN communication network using FlexCAN component through an applied instance.%基于
CAN(Control Area Network)硬件原理模型,深入剖析了CAN总线的仲裁、应答及报文过滤机制等通信机理,提出了CAN总线简化硬件电路设计.以此为基础,对Freescale MCF52235的FlexCAN模块底层驱动的封装方法进行了分析研究,根据嵌入式软件工程原则,给出了满足移植与复用要求的FlexCAN构件设计,为同类应
用提高开发效率、增强系统稳定性提供了技术支持.通过应用实例给出了使用FlexCAN构件建立CAN通信网络的实现方法.
