Buttons

Thank you Mark!

As of right now our buttons are set up as momentary. What we want it to do is when we push a button a cylinder goes out and when we push that same button it retracts. From a programming side I guess I'm asking how exactly a person would do this.

LabVIEW Examples look for the one named Button Toggle Action.
It's about halfway down the page.
I think that's what you want.

There is also a VI for this provided in the examples NI wrote. Check out

Program Files >> National Instruments >> LabVIEW 8.6 >> examples >> FRC >> Driver Station Inputs >> Joystick Button Latching >> Joystick Button Latching.vi

How can I do easier for the driver by making it 2 buttons. For example making one increment and the other one decrement. Lets assume that we have 7 positions:

Position1: to take the tube from the ground
Position2: 30 inches
Pos3: 38 inches
Pos4: 67 inches
Pos5: 75 inches
Pos6: 104 inches
Pos7: 112 inches

Let button increment be Button 2 on Joystick 2 and
Let button decrement be Button 3 on Joystick.

What I want is when I push button 2 if the lifting mechanism in
Pos (x-1) I want it to heightened to Pos (x).

And for the button 3 if the lifting mechanism in Pos (x) I want it to lowened to Pos (x-1).

Those position thing is just an example and what I am asking for is how to use one button repetitively ?


Thanks in advance!!

What does this symbol mean and where can I find it?

That is a Feedback Node.
You'll find it on the Programming->Structures palette
The icon on the palette is just the arrow, but the whole thing shows up when you paste it onto the block diagram.

So now if I wanted to use that button toggle action example on a solenoid how would I set that up? or if you know an example.vi that would be great.

[Mark McLeod]

Assuming you use the double solenoid that came in the 2010 or 2011 Kit of Parts, you'd combine the Double Solenoid Example with the Button Toggle example.

Essentially, you need to put a Solenoid Set into each of the Button Toggle Cases

• Do One Thing (Set the solenoid to Forward)
• Do The Other thing (Set the solenoid to Reverse)

Well that makes sense haha thanks for all the help Mark.
