摘要
利用PC机的并行打印口进行数据采集与控制一直是微机应用者所关心的课题。文章简要介绍EPP工作模式下数据采集系统的硬件设计。讨论了利用VB在Win98下实现数据采集的软件设计方法,并给出了详细的VB程序代码。实验结果表明,该系统能够很好的实现数据的实时采集和显示。
The data acquisition and control by the use of the PC′s parallel port is a matter of interest to PC′s users. This paper briefly introduces the hardware design of the data acquisition system under EPP mode. It focuses on the software design system under Win98 by using the VB tool. And a detailed VB program is given. The experiment results show that the WINDOWS system can realize the functions of real data acquisition and visual presentation.
