基于C8051F040 CAN总线的测控节点设计

A Design of Measuring & Controlling Node Based on CAN BUS of C8051F040

CAN总线已被公认为是最有前途的现场总线之一,在汽车以及工业控制领域已得到了广泛应用。本文以集成有CAN总线的C8051F040微控制器为核心,设计了测控节点的软件和硬件。文中首先简要介绍了CAN总线测控系统构成,然后对C8051F040自带的CAN总线控制器进行了阐述,最后详细的说明了测控节点的软硬件设计方法。

As one of promising fieldbus, CAN bus has been extensively applied for automobile and industrial control. This article designed a measuring and controlling node, including software and hardware, which was mainly made of C8051F040 MCU. First, the paper introduced CAN bus system briefly, then described CAN bus controller of C8051F040, finally detailed the method of software ＆ hardware for measuring and controlling node.
