摘要
介绍基于TMS320F2812 DSP的CAN总线的设计及应用方法。在分析CAN总线的主要技术特性及CAN总线在工业控制系统中所处的位置之后,给出DSP与CAN的硬件设计框图。描述CAN节点软件设计同时给出初始化流程以及发送程序流程图及部分代码。介绍的设计方法易于掌握且具有较强的灵活性和通用性,可用于多种工业现场控制。
The paper introduces the design and application methods of TMS320F2812 DSP-based CAN bus, and presents the block diagram of DSP and CAN hardware design after analyzing the main technical features of the CAN bus and its position in industrial control systems. It also illustrates CAN node software design with initial flow, sending procedure flow and codes. The design methods introduced here can be learned easily, they have high flexibility and universality and can be used in some industrial field control.
