Tool/software: Code Composer Studio

I have a question that how to use FFT fuction in CCS. And my hardware is DSP C6713.

I try to use but always not working.

Can anyone else give me some suggestions. Like what the main library I need to include? Or how to call the FFT function in the right way.

Hi Jeffery,

If you would like to start using FFT calculation on C6713 DSP I suggest you to start with reading C674x DSPLIB article at:
processors.wiki.ti.com/.../C674x_DSPLIB
where is described how to install C674x DSP Library and how to use it.
Then you can find more detailed examples in Accessing DSPLIB in Processor SDK RTOS at:
www.ti.com/.../sprac64.pdf
Pay attention on DSPF_sp_fftSPxSP_r2c_d.c example.
Also TMS320C67x DSP Library Programmer’s Reference Guide should be helpful:
