本文在将嵌入式实时操作系统μCOS-II 移植到S3C44B0 的基础上,将CAN 总线通讯程序作为一个模块植入μCOS-II 之中,形成一个CAN 总线智能节点。阐述了CAN 总线智能节点的设计思想,硬件构成及软件设计。 关键词:μCOS-II;CAN 总线;S3C44B0; RTOS Abstract: On the basis of transplanting RTOS μCOS-II to S3C44B0, a CAN programming module has been embedded into μCOS-II as a building block and so a CAN node has been realized. The design method, hardware and software of the CAN node were described in detail
