2019 LabView Core 1 exercise 8-3 question

[ChienNano]

I am doing exercise 8-3 in 2019 LabView Core 1 and cannot reproduce the same results.

According to the tutorial manual, the max and min value outside the loop suppose to show the min and max once i stop the vi, but it doesn't show.

It uses the Signal Processing's "Amplitude and Level" and "Array Max & Min" blocks.

Could somebody help me and tell me how to fix it? my VI is also attached.

Really appreciate,

Chien

Sorry I am new to this Forum, and I don't know how to start a new post.

Wondering if someone can teach me to start a new post to ask question? I really appreciate.

How are you stopping your VI?

Did you use the Stop boolean button control?

[ChienNano]

Highly appreciate.

I pressed the abort stop button on the top left corner, not the stop button for the while loop.

Now, it works.

Now you know you can't do that.  That is "Abort" which means stop your code dead in its tracks.  It never has a chance to exit the while loop and update those indicators.

The abort button should only be used for runaway code and debugging purposes.  Never in normal operation.

I would have thought the purpose of the button would have been covered in a lesser earlier than #8.

Also, the button called "Run Continuously" should be rarely used and only for debugging purposes.  It is helpful for when debugging a subVI that doesn't have a loop  and has a couple inputs and outputs and you want it to keep running while you test out various inputs to see what the resulting output would be.
