摘要
以TMS320F2812DSP增强型控制器eCAN为中心,构建基于CAN总线的电动轮椅车通讯系统。重点介绍了CAN总线通信中利用eCAN构建CAN网络的硬件节点设计,给出CAN总线波特率计算方法、CAN软件设计流程和对应的C语言初始化设置,发送接收调试程序。该设计使各控制单元具有统一的通信接口、较高的波特率,已成功应用于电动轮椅车控制系统中。
Take TMS320F2812DSP eCAN for enhanced control center,constructed electric wheelchair communication system based on CAN Bus.The hardware node design of CAN net was mainly introduced and designed.The method of baud rate calculation and program flowchart of CAN Bus were also presented.Furthermore C language initialization set-tings,send and receive programs were debugged and passed.The design makes every unit have unified communication interface and higher baud rate,and has been successfully used in control system of electric wheelchair.
