Hi, In the '../gr-usrp/src/usrp1_source_c.cc' file there is a function 'copy_from_usrp_buffer'. I would like to analyze the complex signal converted from 16-bit interleaved I and Q signal.
You can try ../gnuradio-examples/python/usrp/usrp_rx_cfile.py for this purpose. I have changed the 'usrp1_source_c.cc' file to open a file using
fstream class and copy the complex signal onto this file. I have implemented this in the function 'copy_from_buffer'. I built GNU radio software again after the changes. I assumed this would work. But it is not. I am sure to be missing something. Debug prints say that this file is not being opened while this file can be opened by any other C++ program that is not part of GNU software.
Or is there anything that I have to change in .i file as well? IT depends, how would you like to call your object from Python. As long as you dont need to call it from Python, change in .i-file is not required. So far, its not clear whether you are controlling your file from outside/Python or its part of general_work function. PS: Next time you update your gnuradio from svn, possibly the changed file will be replaced. Thanks for any and all help.
