摘要
本文论述了基于USB接口技术的CAN总线适配器的设计与实现。系统采用Philips公司的USB接口芯片D12与单片机进行通信,并和PC机通信而编制出友善的设备应用程序。在USBFCAN的通信中,使用现场总线CAN网络技术,制定了用户层通信协议与USB协议的统一对应关系;在通信中,提出了信息双向传输的具体解决方案,保证信息的完整传输;实现了USB设备的WDM驱动。
The paper mainly discusses the design and realization of the software of central station of the USB interface based on CAN（Controller Area Network）. The article sets forth these tasks as follows. The single-chip programs the firmware to PDIUSBD12 which is a kind of USB interface chips. The system uses the field bus technology and applies the full solution of the information intercourse in the communication of the CAN/USB interface. It insures information＇s regularity and realizes the WDM initialization of USB device.
