Application of Can-Bus in Embedded Vehicle Body Control System
Yanxia Liu, Shufen Li, Yuqiu Song · 2009
A new system design aggress with the CAN2.0B is put forward in the paper. It focus on the hardware and software design of intelligent node at the core of microprocessor S3C44B0, which is a SAMSUNG's 32-bit RISC high performance micro-controller. MCP2510 take as the CAN controller, which is a Full CAN protocol controller implementing CAN specification V2.0 A/B and receive standard and extended messages. In addition, the TJA1050 is the interface between the Controller Area Network (CAN) protocol controller and the physical bus. In addition, a fixed priority DM algorithm is used to assign the priority for each message and get a better result. In software, UC/OS-II multitask operation system is used. It is a indeed real time operation system suited for industrial control and better than anyone else.
