摘要
本文设计了一种基于AT89S52及USB总线接口的数据采集系统,该系统采用BURR-BROWN公司推出的新型12位A/D转换器ADS7804对多路模拟信号采样,通过PDIUSBD12芯片实现数据采集系统与USB总线的接口,实现了基于USB接口的高速数据采集系统。
This paper designed a data acquisition system based on AT89S52 and USB interface. In this system BURR - BROWN's new 12 - bit ADS7804 converter was used to collect data of multi simulative signals, and based on PDIUSBD12 chip realize the data acquisition system interface with USB, and the high - speed data acquisition system based on USB was implemented.
