Rotate 1D Array continuously

[Sugandh]

Hello 

I am generating Sine Wave and sampling it at 12 samples/ Cycle and storing it in the array. I want to rotate this array continuously one sample at a   time. Suppose my array is [20 10 5 3 1],  I want this array as [1 20 10 5 3] (the last element become the first element)next time I want this array as [3 1 20 10 5 ].

Any Suggestions.

Thanks

You can use the 'Rotate 1D Array' VI in the Array palette.

By Using 'Rotate1D Array' Array rotated one time only. I want to rotate 12 times. Or continuously.

Any suggestions

Sorry, I didn't check out your VI before suggesting the Rotate 1D vi.

The above code should rotate the array once per loop.

You can connect the Waveform Graph to the output of the Rotate VI to view the sine wave changing phase.

It would be more universal if you would rotate based on the array size. This way you don't need to change constants and cases whenever the requirements change.

(Insert a "Negate" on the blue wire before the "rotate array" node to rotate the other direction)

Of course the "simulate" should be before the loop because the output is constant.
