Title Redevelopment of CAN-USB Converter Based on VC++ ---Used in Electric Vehicles
Abstract CAN bus communication network since the eighties the world developed by the German Bosch company later, after twenty years of rapid development, with its unique design and high reliability in automotive applications occupy a dominant position. The issue is in this context, the design of a network based on CAN bus PC software.
Paper introduces the development of technology and the advantages of CAN, in the second part of the CAN protocol, as well as a brief introduction Visual C + +, and the associated dynamic link library described. The third part describes the general CANUSB converter basic principle and method.
The fourth part focuses on the CAN-USB converter PC software secondary development. First introduces the basic framework and flowchart software, and low-speed CAN comfort systems and high-speed CAN interface motor and battery systems were produced graphic interface so that it can send and receive data. Initialization data for the system to achieve an interactive, so that it can adapt to the requirements of different working conditions.
