单总线技术的应用降低了多通道测控系统布线的复杂性。但是由于所有的单总线器件均并联在一条信号线上,因此区分出这些单总线器件以实现它们对单总线的分时驱动,成为单总线技术中的关键问题。本文介绍解决该问题ROM 搜索算法的设计与实现。 【关键词】单总线; ROM 搜索算法;多通道 Abstract: The appliance of the 1-wire technology reduces the complexity in the multi-channel monitoring system. But because all devices are connected to the single wire, it is a key problem to find every device from the 1-wire and drive them time-sharing. This paper will introduce the design of the ROM search algorithm in solving this problem. Key words: 1-wire; ROM search algorithm ; multi-channel
