Abstract: In order to solve the problem of communication of controller area network (CAN) bus data between different devices, a wireless communication system combining digital signal processor (DSP), CAN bus technology and ZigBee communication technology is designed. The system forwards CAN bus data through ZigBee, and encrypts the forwarded data through data encryption standard (DES) algorithm on DSP platform. The detailed process of the system from software and hardware design to specific implementation is presented and experimentally verified.
