摘要
基于TMS320F2812的水下自主航行器CAN总线通信,其DSP节点可处理数字信号和控制电机,采用CPLD设计TMS320F2812外存接口。内置eCAN模块可置为标准CAN控制模式,并可通过SCB位选择SCC/eCAN模式。软件流程含eCAN初始化、主节点接收外部节点信息、主节点和其它节点向另外CAN节点发送信息。
he CAN bus communication is applied in autonomous underwater vehicle (AUV), the external storage interface of TMS320F2812 is designed with CPLD, and digital signals is processed and motor is controlled by using DSP node. The built-in eCAN module of TMS320F2812 was set into control mode of criterion CAN bus, and SCC/eCAN mode was selected through SCB digit. The software flow chart includes initialization with eCAN, received message of external node by host node, transmitted message to CAN the CAN bus node by host nodes and other ones.
