Communication System Design Based on TMS320F2407 with CAN Bus

Abstract

In order to keep the communication fast and stable between a variety of control modules, the CAN bus communication system was designed in this paper. CAN bus communication system was designed as follow: the eCAN module of DSP chip TMS320F2407 was applied as CAN controller and the chip SN65HVD230 was applied as CAN transceiver, a variety of control modules was linked by the bus. For illustration, the chassis communication of a security robot is utilized to show how the CAN bus works. Empirical results show that the chassis communication of robot security is fast and stable with CAN bus. The CAN bus communication system designed in this paper can solve the unstable problem in the communication between control modules; it can be promoted to other control system.
