Design of an Analysis and Detection Device for CAN Bus

For problems that normal CAN adapters used for monitoring CAN bus are expensive or cannot realize accurate and real-time monitoring, an analysis and detection device for CAN bus was designed by use of S3C6410 microprocessor, the whole structure was given and software and hardware design schemes of the device were introduced in details. The device is simple in operation and cheap, and can detect CAN bus equipments with different communication protocols and baud rates, which provides a fast and accurate solution of monitoring and fault detection of CAN bus.
