Weird built-in GraphFF Magnitude scaling

[steph_tsf]

Thanks everybody for that very interesting discussion. I think we can close it. Finally, I don't see any bug in the Flowstone/Synthmaker FFT, and let's move to the next stage, which is the implementation of a FFT-based Spectrum Meter. See it here : http://www.dsprobotics.com/support/viewtopic.php?f=3&t=1525

Later on I may come back, asking why the FFT is outputting more than (N/2)+1 pairs. Are the pairs beyond (N/2)+1, the negative-frequency related pairs? They look symmetric. What can we do with this?

I discovered this, realizing that a Green Graph (Array Section) was needed, for saying to the next Green Block, that we only need to read the first (N/2)+1 magnitudes from the FFT.

Thanks again,
Steph
