Korbi,

Please see this C55x benchmark app note. It has an example that uses the Hardware FFT and should provide some guidance on how to implement the use-case that you are looking for.

http://www.ti.com/lit/an/sprac34/sprac34.pdf

Note that the example was tested on C5535. The cmd file defines the location of the hardware fft drivers. Verify the correct location of the hwfft drivers for your device in the device user guide and change the cmd file accordingly if needed.

Hope this helps.
