基于S3C2410与MCP2515的CAN总线接口设计

Interface Design of CAN Bus Based on S3C2410 and MCP2515

利用SPI接口为S3C2410微处理器扩展CAN总线接口,以CAN在车载网络中的应用为背景,从DLL动态链接库的实现、注册表设置、驱动程序的编译三个方面,详尽阐述了MCP2515 CAN控制器在WinCE下的流接口函数的实现.采用该方案扩展的CAN总线接口已经应用到自主开发的车载终端无线传输系统当中,经实验表明,取得了良好的数据传输效果.

This paper expanded CAN bus interface for S3C2410 by SPI interface,explained the software design solution about the stream interface functions in dynamic link library,registry settings and the compilation of the driver under the background of CAN application in vehicle network.This solution has been applied into independent designed vehicle wireless transmission system.The experiment shows that the system achieved good results in data transmission.
