button Switch

[aaeamdar]

I don't know how to use LabView (to me it's a waste of time) and I'm not involved with the programming on my team. However, you can still create a variable in labview (make it a boolean, an integer, a double, who cares). And then make it TRUE or 1 when you press the button and flip it each successive press. And then assign the motor value based on that.

To remember something from one time you process joystick data to the next you need to use either a shift register, a feedback node, a local variable, or a global variable. Any of these will work. Then you do to that storage what the code above showed. You sometimes flip it, and use its value to affect the motor speed.

I'm not sure exactly what to use but I think it would involve shift registers or select vi's

I made a primitive toggle switch. But it will only activate/deactivate at a precise time. Probably like every millisecond or something. This is a picture of what we have. The only issue is the starting and stopping at the right time.

You would use shift registers.

Create a false constant outside of your loop, and feed it to the shift register initializer, then have your joystick button feed the case indicator of a case structure. in the true case, put an inverter (NOT gate, on the Boolean tab), in the line, in the false case, just run it straight through. now feed that to the shift register output. tee the motor on/off into that wire now. I hope that made sense, I'd make a simple vi and show you, but i dont have LabVIEW on this pc.
