FFT build with DSP |

hello Shawn Steenhagen,
I thank you for your answer.
I've done so you said me.
I took the magnitude of the result of rfft().
then I plotted it in ccs, but I haven't got the expected result. I
expected to see only one peak, that correspond to the frequency of the
sine.
And if I take a rectangle input, then I don't see Harmonic waves and
any peaks.
I would like to sent you my quellcode or show you it somehow. It can
be possible, that I write only one Line false, and that make my plott
fals.
can I upload my project somewhere on this site or like attachment in
my message?
thank you. |

You could probably cut and paste the high level main code showing how you
are generating the sine wave, how you are calling the rfft( ) and how you
are calculating the magnitude. Then perhaps myself (and others) will be
able to help you, but I can't commit to debugging your project for you via
this newsgroup.
