Yes I used a scope to display the frequencies in output.
I don't know how accurate it is but using a StopWatch I measured the time when the callback is called and it looks like every 1ms I have a value despite the parameters I have used. This raised up my doubts about how often the FourierUpdate callback is called.
I am now trying to give the fourier frequency coming from the FFT in input to a GenericReal component. It would be nice to have a more detailed description of what GenericReal does and how the internal buffer handles the data in input, in particular when new data (from fft) arrives as time goes. Could you please clarify that for me?
The solution is really close
