【摘要】 为解决嵌入式WINCE操作系统下管理与操作CAN现场总线设备的应用难题,采用WINCE设备驱动程序实现对CAN控制器访问并操作,并通过应用程序访问设备驱动程序来实现操作系统核心对CAN控制器操作并管理.实现中首先搭建以ARM9s3c2440为硬件核心的处理平台,在处理平台上扩展连接CAN总线设备,通过在核心处理器上移植WINCE操作系统,完成WINCE下CAN设备的流接口驱动程序,然后编写应用程序访问CAN设备的驱动程序.实现结果表明在WINCE操作系统下能有效地操作CAN总线设备.更多还原

【Abstract】 To solve the application problem on management and operation of CAN-bus device under the environment of embedded WINCE operating system,the research is based on the methods of using WINCE device driver to search and operate CAN-bus controller,and application programmer to search device driver and realizing the management and operation of CAN controller exerted by the operating system core.ARM9s3c2440 was used as the hardware core processing platform,extend the CAN-bus device,and then transplant the WINCE operating system on the core processor,and complete the CAN-bus device driver under WINCE.Finally write an application programmer,which searches access to the CAN device driver.The realization shows that CAN-bus device can be effectively operated under the WINCE operating system.更多还原
