Design of TTCAN Controller Based on DSP

基于DSP的TTCAN控制器设计,采用双冗余CAN控制系统。其高层协议利用TMS320LF2407A实现,底层协议利用MCP2515控制。当有数据传输时,由DSP提供SPI总线的时钟。该控制器软件系统包含系统初始化与主程序模块,其中主程序模块又包含冗余处理、TTCAN协议实现及通信模块三部分。

The design of TTCAN controller that based on DSP using dual CAN redundancy control system, The system used TMS320LF2407A to run the high protocol and used MCP2515 to control the bottom protocol. When having data to sent, the DSP can offer the clock of SPI. The software of the controller includes initialization of system and the main program. The main program consisted of three parts, such as management of redundancy, realization of TTCAN protocol and communication program.
