目前,在用微型计算机控制的系统中,A/D、D/A转换器已成为控制电路中不可缺少的组成部分,且转换位数也逐渐增加.在这里,我向大家介绍一种8位A/D转换器,通过其新颖的逻辑和独特的工作方式,将会使大家得到一些新的启发. A/D转换器同许多通用微处理器相接,不需要连接逻辑电路,即使在最不利的情况下,也仅需要一些逻辑电路,然而,接口软件简单,可检测,对于作为多路汇编语言通路的多数微处理器而言是很有使用价值的.
At present, A / D, D / A converters have become an indispensable part of the control circuit and the number of conversion bits has gradually increased in microcomputer-controlled systems. Here, I introduce an 8-bit A / D converter, through its novel logic and unique way of working, will get some new inspiration. A / D converter with many common microprocessors phase, do not need to connect the logic circuit, even in the most However, the interface software is simple and detectable and can be very useful for most microprocessors that are multiplexed assembly language pathways.
