calling FFT function from dsplib tms320vc5510

Started by swlow1016 January 9, 2007
this is my first time using tms320vc5510 dsp board by TI.

i need to process my signal using FFT. thus, i had generated a 12 cycle
sine waveform to test the FFT. i had referred to TMS320C55x DSP Library
Programmer�s Reference (SPRU422i) on how to call the FFT function from
dsplib but some how the output was not really as desired. i suspect there
was something wrong with my source code.

may anyone teach me or show me some example on how to call FFT function
from dsplib tms320vc5510 and how to determine whether the function is
perform correctly or not?

thanks for ur help...
