Dears,I would like to develop a patch in puredata [1] that offers the
possibility of using the USRP via GnuRadio trough interactive
programmed-object interface.For this, the GnuRadio GUI is not needed (I
presume), but I have to find out how It could be possible to pilot every
tasks normally provided by a GUI directly from puredata (like in the way
of WebSDR but with no GUI) .There are several “objects” in pd that coulb
be used for that:- “netsend” and “netreceive” via TCP/IP and UDP- pd-py
(compiled via pd-flext) [at this day I was not able to compile it on
Debian nor OSX…work in progress]Maybe netsend and netreceive could do
that easely.But first I would like to know if It’s possible to make
communicating GnuRadio and puredata.This developpment could be very
useful for GnuRadio and the USRP:- possibility to automatize every tasks
to the USRP - interactive processes- network connectivity using pd (like
WebSDR but without Java…)Maybe you can advice me or even work
toghether for the developpment of this project.Best regards,Cosmin[1]“Pd (aka Pure Data) is a real-time graphical
programming environmentfor audio, video, and graphical processing. It is
the third major branch of the family of patcher programming languages
known as Max (Max/FTS, ISPW Max, Max/MSP, jMax, etc.) originally
developed by Miller Puckette and company at IRCAM. The core of Pd is
written and maintained by Miller Puckette and includes the work of many
developers, making the whole package very much a community effort.Pd was
created to explore ideas of how to further refine the Max paradigm with
the core ideas of allowing data to be treated in a more open-ended way
and opening it up to applications outside of audio and MIDI, such as
graphics and video.It is easy to extend Pd by writing object classes
(“externals”) or patches (“abstractions”). The work of many developers
is already available as part of the standard Pd packages and the Pd
developer community is growing rapidly. Recent developments include a
system of abstractionsfor building performance environments; a library
of objects for physical modeling; and a library of objects for
generating and processing video in realtime.Pd is free software and can
be downloaded either as an OS-specific package, source package, or
directly from CVS. Pd was written to be multi-platform and therefore is
quite portable; versions exist for Win32, IRIX, GNU/Linux, BSD, and
MacOS X running on anything from a PocketPC to an old Mac to a brand new
PC. It is possible to write externals and patches that work with Max/MSP
and Pd using flext and cyclone.”
