Inputs (buttons) on USB interface board /event case

[Matt V]

Thanks a lot guys! I now see what you mean. Working with hardware is new for me, working with Labview also  haha 

Sometimes I find it very hard to come up with the solutions you gave.. But we'll keep on trying..

Thanks!

The way it is now with the time-out event is still not correct. When I now press a button on the board it does react but goes back immediately to the time out event so it does not stay in the event, and that is what I wanted.... I think this program needs another set-up without the event case... Someone better idea?

You have nothing in the timeout event and you have that silly value(signaling) property. You posted an old VI. A event structure is supposed to keep re-running the timeout event as long as there is no user event. I have no idea what you mean by 'stay in the event'. What does that mean? After reading the hardware, what you want to do?

Oops indeed old VI, hereby my latest

When you press a button on the board you now go to event 2. In that event I want to measure the time and the voltage, so I can calculate capacitor RC time. Do you understand me now? 

[Matt V]

With stay in the event I mean that event 2, were the calculations are done, remains active till another button is pressed which activates another event, for example stop button.

So you want to take multiple readings in the 'Input' event? It's not very good style but you could have a for loop that takes x number of readings. The time between readings would be set by wait like you have now.

F*cking hell stupid me, I think this is what I need. I replaced the "input event" for a case structure, now the measuring continuous. Thanks, thoughts in a different direction..

Hello,

I have a new question... I post it here so I do not have to create a new forum..

In my VI I want to measure the time how long it takes to perform the calculations (bottum of the for loop). I tryed it with an equal comparison block, that does not work. It works with the greater or equal comparison block but then the time keeps on running, offcourse it does because the outcome is still bigger then 3,14322. But I don't have a sollution to fix this. Someone has?

Thanks in advance.

Hi Matt,

is has been shown a lot of times before how to measure timings of (parts of) code:

Btw. right now your loop timing should be limited by the "Wait for next multiple" function...
