How to connect this

Still difference with the one from Multitone vi

[Dennis_Knutson]

Then why don't you simply use the multitone if you can't get your other code to work?

[LeoLiu]

Because i want see a dynamic waveform(waveform will move with time goes by)

[JanBarton]

Hi,

is it this what you want?

[LeoLiu]

Thank you man , i have tried this way, but the waveform difference with the one I got from Multitone Generator.vi

I have attached that on the previous page.

[JanBarton]

Hi,

I also have tried to compare the waveforms and they are the same. Please look at attached vi.

[LeoLiu]

Thank you , jan barton

I have attached the vi, this function is exactly I want to achieve, but I want use Express vi to achieve, because I want see a Dynamic waveform

[Dennis_Knutson]

Your starement makes no sense. An Epress VI is no more 'dynamic' than this example or the multitone function. In fact, an Express VI is often less 'dynamic'. You just need to place code inside a while loop. Perhaps you should take LabVIEW 101 before posting any more questions.

I don't know why you feel the need to have it as a Dynamic Datatype, but you can use the Express VI  To DDT to convert it.
