自动售货机中MDB/ICP协议通讯的实现

The Realization of MDB/ICP Protocol Communication in Vending Machine

MDB协议又名ICP协议是由国家自动机械销售协会(NAMA)和欧洲售货机协会(EVA)的有关成员制订,是一套用于协调自动售卖机的主控制器(VMC)与多个外设之间通信的协议。本文提出以STC单片机为例,实现VMC与外设的MDB/ICP协议通讯。

MDB protocol, also known as the ICP protocol is formulated by the concerned members of the National Automated Machinery Sales Association （NAMA） and European vending machine Association （EVA）, it is set for the communication between vending machine main controller （VMC） and multiple peripherals. This paper introduces and presents the MDB/ICP protocol communication between VMC and peripheral using STC Single chip microcomputer.
