摘要
针对现代汽车上的电子控制单元日趋增多带来的线路复杂和线束增加的现状,提出一种基于DSPTMS320LF2407A的CAN模块的通信系统实现方案,以简化线路,提高各单元之间的通信速度,降低故障频率。主要设计了网络节点的硬件电路,并利用TI公司的CCS4.10软件和闻亭公司的TDS510USB2.0DSP仿真器进行了软件设计,实验结果表明本设计成功实现了CAN网络通信。
Aiming at the status that the lines are very complex and the group of lines increases on the modern automobiles with their electronic control units increasing dramatically. This paper puts forward a kind of solution for CAN bus based on TMS320LF2407A, so as to simplify the lines,enhance the speed of communication between the units and reduce the failure frequency. It mainly designs the hardware circuits of network nodes, compile the programs with the full advantage of CCS4.10 software of TI and TDS510USB2.0 of Wintech. The experimental result presents that the design realized CAN communication successfully.
