All,
Mr. Cooley wrote this code sometime early last year, and unfortunately
something in the gnuradio or wxgui code has changed, and this code is no
longer operable.
The error I got in trying to run it with gnuradio 2.8 is:
gnuradio_swig_python.py expects a std::vector<float,std::allocator<float>>
I had an email exchange with Mr. Cooley, and he would like to fix his
code, so any effort would be appreciated in that. And, as he said in our
exchange,
"Now that I think about it, the waterfall Python OpenGL code that I did
was based largely upon the similar wxgui-based fft. So, following the
format of the wxgui versions may help lead you to the right functional
calls, and get the right calls on the GnuRadio side."
