thanks Trond,
I went your way, and actually my stream gets loaded right into the ram
as I wanted..:)
my problem is now that.. doing:
data = fromfile("/root/Desktop/ofdm_encode_1H.dump",
dtype="complex64")
vector_source = gr.vector_source_c(data,True)
self.connect(vector_source,gain)
self.connect (gain, self.u)
I get an error relating to the number of arguments I pass to
gr.vector_source_c
vector_source = gr.vector_source_c(data,True)
File
"/usr/local/lib/python2.4/site-packages/gnuradio/gr/gnuradio_swig_py_gengen.py",
line 6695, in vector_source_c
return _gnuradio_swig_py_gengen.vector_source_c(*args)
NotImplementedError: Wrong number of arguments for overloaded function
'vector_source_c'.
Possible C/C++ prototypes are:
gr_make_vector_source_c(std::vector<gr_complex,std::allocator<gr_complex
> > const &,bool)
gr_make_vector_source_c(std::vector<gr_complex,std::allocator<gr_complex
> > const &)
what am I doing wrong?
sorry for bothering..
and thanks for help
