Hello All,
I'm currently working with a DM3730 processor to get an FFT working on the embedded TMS320C64x+ DSP. I've correctly install DSP-for-Dummies and tested that I can indeed communicate with the DSP. I've run into a problem where I believe the DSPLib function DSP_fft16x16() isn't working for me. I'm testing the FFT with the following complex input:
1+j0, 0+j0, 0+j0, 0+j0, 0+j0, 0+j0, 0+j0, 0+j0,
0+j0, 0+j0, 0+j0, 0+j0, 0+j0, 0+j0, 0+j0, 0+j0
I would expect the following output:
0.0625 + j0, 0.0625 + j0, 0.0625 + j0, 0.0625 + j0, 0.0625 + j0, 0.0625 + j0, 0.0625 + j0, 0.0625 + j0, 0.0625 + j0, 0.0625 + j0, 0.0625 + j0, 0.0625 + j0, 0.0625 + j0, 0.0625 + j0, 0.0625 + j0, 0.0625 + j0
But, I get junk output data instead.
Does anyone have any experience integrating DSPLib with DSP-for-Dummies for the DM3730?
