摘要
针对CAN总线与PC机安全可靠的互连问题,利用内部集成有CAN控制器的LPC2292和符合USB1.1版规范的PD IUSBD12,设计了一种CAN总线USB接口适配器,给出了USB设备端通信、CAN与USB的协议数据转换和CAN通信的软件设计。该设计硬件结构简单,外围元器件少,可靠性高。经实际使用,CAN总线通信波特率可达1 Mbps。
Using CAN controller integrated with LPC2292 in it and PDIUSBD12 accord with the specification of USB1.1 version, designed a CAN bus USB interface adapter. The software design of USB device communication, CAN and USB protocol data conversion and CAN communications was given out. This design has simple hardware, few periphery components and high reliability. The problem that interconnects CAN bus and PC has been solved perfectly. The CAN bus communication baud rate is up to 1 Mbps in practical use.
