Title    Design of PC Communication Software Based on CAN bus Communication System                                          

Abstract

CAN,which is short for Controller Area Network,is the world's most widely used field bus.CAN-bus is mostly used in network formation of industrial control systems and vechile control system.

This paper discussed the background,development status and the research significance of CAN bus, gave an outline of the CAN-bus relevant technical specifications，and designd the CAN communication software based on Visual C++.Functions implemented include:Correctly identify the CAN device and open the CAN channels;CAN messages can be sent encapsulated; CAN data frames can be received,and is able to parse the received data frames;Has a filtering function,do not display the specified protocol frame.At last,Tested and released the software.
