摘要 介绍了以太网与CAN现场总线网间嵌入式网关的软硬件结构设计,描述了uClinux上CAN设备驱动程序的处理流程及其设计方法和技巧。针对CAN协议的特点,为不同实时等级的信息报文设立四个分组,设计了多帧数据发送报文结构,为设备驱动程序的收发缓冲区设计合理的数据结构和管理方法,提高了CAN通讯效率。 The architecture of software and hardware of the embedded CAN-Ethernet gateway were introduced, and the principle, the designing methods and technoloques of the CAN Device Driver in uClinux were described. According to the features of the CAN protocol, data package was classified into four groups with different real-time request; the structure of multi-frame was proposed to satisfy the request of sending mass data; the data structure and the method of management for the buffer of the CAN Device Driver were designed to improve the capability of communication.
