一种单芯片的CAN-USB桥协议及接口设计

Design of Single-chip CAN-USB Bridge Interface and Protocol

针对目前CAN-USB桥接器比较少见且多采用多芯片方案,提出一种通用软硬合成的CAN-USB单芯片解决方案,并给出了其硬件组成和软件架构及协议方案设计和实现的技术要点,详细阐述了桥接器驱动程序和固件应用程序设计。该模块成本低廉,操作简单,传输高效,完全满足1Mbps速率的CAN总线需求,有很大应用价值。

For the current CAN-USB bridges are relatively rare and most of them are multi-chip solutions,a new CAN-USB singlechip solution is supported here with the scalable synthesis of its hardware and software,and the hardware composition and software architecture are also given as well as the design ideas and technical points.And the bridge drivers and firmware application are also elaborated on.With the features of low-cost,simple operation and transmission efficiency,the module can fully meet the needs of 1Mbps rate of CAN-bus,which has a great application value.
