You did not do anything I said. You placed a diagram constant inside the loop and left the swtich outside the loop.

I think you should start with a few LabVIEW tutorials first and learn about dataflow.

Sir

  This time I think I have modified as per your mail.Its working also.

But I have to use double controls for true and false.

Is it possible such that at boolean 0 no output and at boolean 1 output displayed using 1 set of controls

points,speed and angle

thank you for the suggestionsand corrections. file attached.

Threre is only one switch, please exaplain what you mean.

Make the false case empty and set the output tunnel to use default if unwired.

Sir

  thank you I will be trying the above.Sir I have one more query can I change the slope of wave form from square to triangle to trapezoidalby changing the slopes any suggestions please.

thanking you regards

Of course. Just use more points for each segment. The rest is simple math.

sir

using the existing points can I create square, trapezoidal and triangle wave.Sir I am new and just learning labview can u give some more help.thanking you

greetings sir

Sir this time I am generating sine wave .When boolean is true I should get moving sine wave.

I have tried with some examples sub vi.

frequency should vary with frequency control

Sir I also require initial sine then continuous triangle

Sir I didnt get concept of moving waveform generation

What is the significance of the two VIs you have attached?

sine_wave.vi has about four sine generators on the diagram. Please simplify to the essentials and thell us where you have problems. All booleans are diagram constants, thus they cannot be operated when the VI runs. Replace with Controls. Your while loops stop after one iteration.

Func.vi seems to be written by a different person. Who? Why did you attach it?

[kavharshre]

sir

Actually I want to generate a moving sine wave.

I have put two options to generate sine wave.

I have problem in clusters which are going to waveform chart

Sir which is more correct to generate a moving sine wave

I am able to generate a constant sine wave but it should move as boolean is true

thanking you
