时间统计的问题

[redred]

采集的信号大于某个数值时候，开始计时，计时达到指定时间，就停止采集，谢谢

Possible way... using 2 parallel loops.

Loop1: DAQ and check for if X > Y, set boolean i.e. T to trigger timer in Loop2

Loop2: If T is True, start timer. If timer time's up, stop DAQ (in Loop1)

用哪个组件呢，我看Elapsed Time 上没有start之类的输入

[ian_fung · Accepted solution]

You can play around with Reset (for Timer Start) and Time Has Elasped (for DAQ stop)

 PS: attached example code simulating Timer Start and Stop

顺便问一下，你的控制按钮怎么弄的，而且控制框上的停止按钮怎么弄没的

你的控制按钮怎么弄的

Do you mean the STOP button? It is the Dialog Button from Dialog Controls with Key Navigation removed.

As for the small little image "embedded" onto the button, 到我的部落格吧! (not sure if can surf that blog from within China?!)

Basically it is the VI's Icon image copied to the front panel. The image must have a small (min. 1 pixel) opening with white color in order to appear with part "transparent"...

而且控制框上的停止按钮怎么弄没的

Do you mean the Run button (on the menu bar)?
