| 摘 要： | CAN总线在嵌入式系统开发中有着广泛的应用，多数嵌入式处理器没有CAN总线控制器，所以需要通过外部总线自己扩展CAN总线接口，使S3C2440芯片可以控制CAN总线数据的发送和接收，本文采用MCP2515总线控制器扩展S3C2440芯片的接口功能——利用SPI接口扩展CAN总线接口。本文详细介绍了CAN总线硬件的接口设计，并详细说明嵌入式Linux操作系统上CAN设备驱动程序的具体设计。

| Abstract: | CAN bus was widely used in embedded system development, but most embedded processors without CAN bus controller, need to extend external CAN bus interface through external bus. In order to send and receive the CAN bus data by S3C2440 chip,in- terface function of S3C2440 was extended by MCP2515 chip in the paper, which was used in the SPI interface to extend CAN bus in- terface. The design of CAN bus hardware interface was described in the paper. The design of CAN device drive program on the embed- ded Linux operating system was specified in detail. |
