Labview (Coding Help) One button inverses/un-inverses controls?

[JacksonS.]

So I don't know if this is what this forum is for, but as one of two coders in my team (+ the main one), I really get pressured by my team to make everything work, and I can't figure something out for the life of me!

So here's what my team wants:

-One button (In our case button 3 [Y]) needs to invert axes X and Y in our drive system when pressed, until pressed again.

I've tried about 10 times so far and every time I either ruin the code and the robot freezes, or we have to hold Y.

I've tried the RS Bistable Flip Flop vi, but maybe I just dont know how to use it???

Thank you all and sorry I can't code xD,

I think this site works really well when I want to figure out some button actions.

I'd looks for "Button Toggle Action (2014)" to get what you want.

I agree with JY,

I would use a Toggle to switch between the two behaviors (as describes here: Use Joystick Button to Toggle Between Cases Using LabVIEW for FRC) and then would make one of the cases switch the inputs (maybe negating them too...).

I think I might have done something wrong, but I can't see where.

Nothing inverses now. Those values go up to a multiplication on the X and Y axes.

Sorry again for my inexperience!

your false case should look like this.

When the button is not pressed you want to keep the previous value.

[JacksonS.]

Thanks! This works!

The only thing is that it starts immobile, you have to hit Y to begin the process. We can deal with this though!

Thank you!

Here is a simplified version of what you are trying to do.

and it may fix your issue of starting at zero

[JacksonS.]

It did, Thank you!

Would give you 5 kudos if I could!

Hey, we are trying to make this for our motor outputs, and I cannot seem to find the orange node for the program. In which library can we find the node? Thank you!

[Mr.S77]

Had just found it, never mind.
