摘要
本文研制设计了一种适用于 PC 总线的主从式智能同步数据采集模板(卡)。该模板(卡)以8031单片机为核心,实现了多通道模拟输入,程控增益,多路同步采样,12位高速 A/D 转换等功能,特别是采用双向 FIFO 及其联络控制电路,成功地解决了主从 CPU 之间高速数据通信。
The intelligence synchronous data sampling card of master-slave mode nas been investigated,which suits IBM-PC bus.The card takes 8031 as nucleus,so it can realize the functions of multichannel analogy input,programmable gain,multipath synchronous sampling,12 bit A/D conversion etc..Especially the card can solve the prob- lem of high speed data communication between master-slave CPU when it adopts the bidirectional FIFO and control circuit.
