Design and implementation of CAN device driver under embedded ARM Linux operating system

摘要

A distributed CAN bus control system is introduced to meet the demand of real-time capability and system reliability on a mobile robotic control system.The hardware interface design for expanding CAN-bus device on a S3C2410 board is then described.Detailed discussions are made on the general method of device driver designing in ARM Linux and implementation of CAN device driver.Experiments indicate that this system is adequately stabile and reliable,but with a simple structure and easy implementation.
