| 摘 要： | 以太网和CAN总线应用广泛,但由于其通信协议不同,两种总线器件间无法进行数据通信,因此,设计了基于CP2200与C8051F040的以太网总线与CAN总线接口转换电路,并给出部分相关硬件电路与软件设计分析。在保证数据完整和协议可靠的前提下,通过握手协议和简化的以太网协议,不仅实现了以太网数据与CAN数据的转发,同时还顺利的解决了以太网的高速性与CAN的低速率冲突,以及两者数据包之间的大小不同的矛盾。

| Abstract: | In the development of actual application,Ethernet and CAN bus are used very extensively.Owing to its various communication protocols,the communicating between two kinds of bus device can’t be carried out.Therefore,in order to solve this problem,the Ethernet-CAN bus interface circuit based on CP2200 and C8051F040 was designed in this paper,and part of the related hardware circuit and software design analysis were given.On the condition of data’s integrity and protocols’ reliability,through the handshaking protocols and the simplified the Ethernet protocol,not only the data switching between CAN and Ethernet was realized,but also the differ in velocity and packet size was solved. |
