Re: [Discuss-gnuradio] Modifying C++ Files

[Ben Reynwar]

Hi Sam,

In bpsk.py you'll see the line

constellation = digital_swig.constellation_bpsk()

If you change this to:

constellation = digital.constellation_calcdist((1+0i, 0+0i), [], 1, 1)

, you should get the change in modulation you want.

You only need to mess with the digital_constellation.cc file if you
want to implement an efficient non-generic
decision maker for this modulation.

To know why what you're doing isn't working, I'd need to know what
modifications you're making to the .cc file.  It sounds like you're
doing everything right.

Cheers,
Ben
