提出了一种基于 AVR 单片机的开放式的嵌入式运动控制器平台,并定义了供功能扩 展的MM-BUS 总线接口。该平台充分利用了AVR 单片机资源,采用了CPLD 芯片作为辅助。介绍了该平台的硬件结构和软件组成,并给出了一个应用实例。 关键词:AVR;嵌入式;通用运动控制器;CPLD Abstract: In this paper, a method is put forward which accomplish the opened and embedded motion controller platform based on AVR micro-controller, and define a standard bus interface of Moving Master bus for expansion function. This platform makes full use of the resource of AVR micro-controller, adopt the CPLD chip as the assistant circuit. This paper introduces hardware and software architecture of the embedded motion controller platform, and gives an application example. Keyword: AVR, Embedded, Universal Moving Controller, CPLD
