| Abstract: | 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. |
