| 摘 要： | 介绍了一种基于DSP的CAN控制器和USB芯片的USB总线和CAN总线的通信模块的设计，提出了一种使用USB接口实现CAN总线网络与计算机连接的方案。利用USBl00芯片可在不了解任何USB协议的情况下，完成计算机RS232串口升级为USB接口，同时CAN接口采用DSP片上CAN控制器，硬件设计极为简单。在DSP的控制下，PC机与CAN节点可以双向通信，通信波特率可高达1Mb／s，传输数据稳定，可靠。实验证明，运用TMS320F2812片上eCAN模块来构成CAN总线通信系统更为简单，实用。

| Abstract: | The design of a communication module between USB and CAN bus based on CAN controller of DSP and USB chip is presented. A scheme that implements the connection between CAN bus network and the computer by USB interface is proposed.. With the help of USB100, it can update the RS232 serial port of a computer to USB interface in the situation of unknowing anything about USB protocol. The hardware of system is extremely simple as a result of using CAN controller on DSP chip. Under the control of DSP, PC and CAN node can communicate with the baud rate of 1 Mb/s. The data transmission is stable and reliable. The experimental results show that the system of CAN bus communication made up of eCAN module which is on the chip of TMS320F2812 is simple and much more practical. |
