摘要
介绍SM89516A控制下的数据采集卡的整体设计过程。系统采用SM89516A为主控芯片采集由16位模数转换芯片ADS7805转换后的16位数字量;经SM89516A处理后的16位数字量完成与计算机通信。
The process of the design for data collection card is introduced in this paper, which is controlled by SM89516A. This system uses SM89516A as major control chip to collect 16-bit digital values which is converted by the 16-bit A/D converter ADS7805. The 16-bit digital values managed by SM89516A are used to communicate with computer.
