基于LabVIEW数字量输出功能的扩展

The Expansion of Digital Output Function Through LabVIEW Software

在测控技术应用中,常受到普通数据采集卡数字量输出的限制,通过采用"复用+片选+锁存"硬件电路设计理念,实现数字量输出口的扩展;结合LabVIEW软件在硬件控制中的优势,实现直观、可靠的软面板操作.

In common applications of Measurement Control technologies,the hardware circuit design of ＂Reuse plus Chip select plus Latch＂ can be adopted to break the digital output limitation of current data acquisition card.Making full use of the distinctive advantage of LabVIEW software in the field of hardware control,we have developed an intuitive,reliable software panel operation.
