observe the frequency from voltage signal using MyRIO analogue pin

[Gappiya]

Hi all i am still student and i am doing a project to build simple NILM based power analyzer using MyRIO. I want to capture the characteristics like  frequency, phase angle from the voltage and current signal. Since the MyRIO gives integer values i need to generate waveform to use waveform measurement vi. and get those characteristics. I have use this method but still i dent get any values for the frequency or phase angle. 

what would be the problem.
Thank you

Hi gappiya,

please do some beginner tutorials before starting to code in LabVIEW: your image shows several misunderstandings typically done by beginners...

Right now you create waveforms containing exactly one sample: you cannot determine any frequencies or phases from single samples!

The myRIO gives no integer data as can be seen by the orange wire. Instead you get scalar samples...
