[Discuss-gnuradio] usrp-gnuradio-puredata

[[ Cosmin ]]

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

"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."
