An Embedded CAN-BUS Communication Module for Measurement and Control System

A CAN-BUS communication module for embedded system has been proposed in this paper, together with its hardware and software design. The motivation to design such CAN module is try to ease the development of CAN-BUS based embedded applications. With the CAN module, the engineers do not have to understand all aspects of CAN protocol, CAN controllers and CAN transceivers, therefore an industry automation application can be built conveniently. The CAN module provides simple hardware interface and highly abstracted software communication protocol, due to the abstraction and integration of all CAN related communication functions in an embedded module, and therefore can be easily embedded into any MCU based systems. The CAN module can send/receive data following the pipe based communication model. With the help of the software package, the CAN-BUS communication would be transparent to the micro-controllers of the nodes in the system.
