| 摘要 |
随着企业生产线控制的本地化、 自动化 ,现场总线控制系统得到越来越多的关注 ,传统的51系列单片机甚至ARM7系列已经逐渐不能满足其对复杂度、 智能化需要。 由于许多高性能的ARM9系列处理器并不集成CAN接口 ,本文提出了一种基于ARM920T的现场总线控制系统 ,详细讲解2种CAN模块扩展的方式 ,以及基于一种实时操作系统eCos上 CAN 驱动的开发 ,最后对 2 种扩展方式进行了比较。
关键词: CAN 总线; ARM; eCos ; 驱动 |

With the localization and the automatization of product line in corporations , Fieldbus cont rol system claims more and more at tention. Traditional 51 SCM (single chip microco mputer) and ARM (advanced RISC machines) can not meet the need of complication and intelligentization. An embedded fieldbus cont rol system based on ARM920T and eCos is proposed. Since there is no build in CAN interface in most of ARM9 chip s , this paper puts forward a field bus cont rol system ( FCS ) based on ARM920T , and int roduces two methods to expand CAN bus and their driver
development on eCos , an embedded realtime operation system. And it compares these two approaches at the end.
Keywords : CAN Bus ; ARM; eCos ; Driver |
