The compiler requires a couple of environment variables to be set, plus
the path statement needs to be modified. This is described in the help
I would also start with the helpfile for your application. If you
agian look into the help file, but this time for the FFT demo you will
see how the FFT example has been tied into the breakpoints and graphics
display. It is a simple matter of searching that array.
When you have identified the signal of interest you will need to extract
the freqeuncy and phase. To learn how to extract an accurate freqeuncy
have a look at the spectrum analyzer demo. That demo uses centroid
location to indicate frequency accuracy to 0.01 Hz resolution (or
better) even though the FFT bin spacing is typically in the 10-50Hz range.
Hope this helps
My lab group is trying to design software for the VC33 University kit to
do the following:
1. perform an FFT on a corrupted input signal
2. Identify the corrupting sinusoidal signal 3. Apply a notch filter
centered at the sinusoidal signal 4. Output the signal
Our experience with DSP and assembly is somewhat limited. We all have
had experience programming in assembly for the HC12 and my DSP
experience is limited to a class I am currently taking on the
fundamentals of DSP. The windows debugger that comes with the kit is
confusing to me. I can load the sample ASM files and assemble them, but
if I try to use any of the c code, i cannot. Is the c compiler linked to
dsk3dw.exe? If not, what should I use? Are there any third party
programs that work better than dsk3dw? Second, what would be a good
starting resource to working with programming dsp chips?
Thanks for your help!
