Can generate trigger signals from buttons blinking on the monitor during the data acquisition?

[kuzing]

Hi everyone,

May I ask you that we can generate trigger signals from buttons blinking on the monitor during the data acquisition or not?

I found that on the DAQ Assistant with my  NI DAQ card,NI USB6009, it has a digital trigger which I thougt I have to generate it with a hardware. Though, what I need is to generate trigger signal from buttons blinking on the monitor. Can we apply this to DAQ Assistant? Because I need to calculate the acquired data referencing to different trigger signal.

(what I can do now is add a comment when any button blink.)

Hi kuzing.

By “buttons blinking on the monitor” do you mean to Boolean indicators on the front panel of your VI? Or do you have a device that has many blinking LEDs?

If you mean to Boolean indicators on your front panel what you need is an event structure.

If the changes of the Boolean values are made programmatically instead of in the front panel, you might want to check the following document

Good luck!!
