摘　　要：介绍了一种基于S3C6410的CAN总线接口扩展方案,通过SPI接口对CAN接口进行扩展,并给出具体的硬件电路。重点研究了WINCE系统下独立CAN控制器MCP2515的驱动程序。结合CAN总线技术规范和MCP2515的特点设计了相关的软件代码,编写了CAN流接口驱动程序,实验结果表明,在WINCE系统下能够较好实现CAN总线的通信。The CAN-Bus interface expansion program based on the S3C6410 is introduced. The CAN bus is ex- tended through the SPI interface. The specific hardware circuit is also given. Emphasis is put on the CAN controller MCP2515 driver based on the embedded operation system WINCE. The related code is designed under the CAN-bus specification and MCP2515 features. The CAN bus stream interface driver is designed. The experimental results show that the CAN-Bus communications is good.
