This is a DC, and almost zero input. Try changing it to
inFFT[i] = i;
and see what happens.

Hi!
Any body tried the FFT routines given in visualDSP compiler manual.....
we are trying to use the Library routines rfft_fr16 but we are unable to get
proper reslts.........
we have checked Compiler documentation, this is just an example code we need to
test...........
the thing is outFFT is always showing "zero" in the following program
we are using visualDSP 5.0
#define EE_LENGTH 8000
#define FFT_SIZE 256
#define SAM_RATE 16000
