Hello,
I've been trying to use the C6748 LCDK to take a number of real time samples, take the fft of this and then do some processing to the fft. To do this I have been using the microphone input and following some of the examples found in "Digital Signal Processing and Applications with the OMAP-L138 experimenter", believe I have the sampling working correctly. However, I need to take around 8000 samples and when I try to use any of the fft functions, either the ones used in the book or ones from the dsp libraries, it will get stuck. After playing around for a while, I figured out that it only does this for high number of input samples, if I take only 32 it will go through but anything larger than that makes it stop working. So my guess is I am somehow using the fft functions wrong or could be something else basic that i am missing. I have very little experience using DSP's, so I am very unfamiliar with them. Any help would be appreciated.
