摘　　要：CAN(控制器局域网)总线技术在嵌入式系统开发中有着广泛应用,虽然CAN总线通信控制芯片众多,但是要在嵌入式操作系统下扩展CAN总线设备需要设计相应的驱动程序。文中针对CAN总线的技术特点,并结合嵌入式Linux操作系统的优点和嵌入式处理器S3C2410丰富的片内资源,实现了在S3C2410上CAN总线设备的硬件扩展设计,介绍了嵌入式Linux系统上的CAN设备驱动程序的开发流程以及设计方法和技巧,并描述了CAN设备驱动程序的具体实现。CAN-bus technology is widely used in the application of embedded operation system. Although there are many kinds of CAN-bus controlling chips, corresponding deriver still needs to be designed in order to expand CAN-bus device in the embedded operation system. In this paper, to meet the demands of technical characteristics of CAN-bus, a hardware design for expanding CAN-bus device based on S3C2410 was accom- plished, which combined the advantages of the embedded Linux operation system with the plentiful resources on S3C2410. The development procedure and design skill of CAN-bus driver are also introduced and details of implementation of CAN-bus driver are described in detail.
