Manolis Surligas c2b66c5887 Add waterfall and Ogg sink at the NOAA decoder flowgraph 2017-07-21 18:34:27 +03:00
Manolis Surligas f3de63caf3 Add support for passing manually various device parameters
All flowgraphs now support user defined parameters for most of their
configuration capabilities. These include:
* RF gain
* IF gain
* BB gain
* Custom device arguments for setups with multiple SDRs. These
coresponds to the 'Device arguments' field of the Osmocom source block.
* Antenna selection for devices with multiple antennas (USRPs, etc)

Changing sampling rate is not supported (yet).

For listing the arguments just execute <flowgraph> --help in a terminal
window.

Manolis Surligas efea5fdda1 Fix gnuplot issue
In some cases (crash, inproper termination) a flowgraph failed to
produce a binary file that had exactly the proper number of float
numbers in order the gnuplot script to be able to convert it in a matrix
representation.

The updated script tries to truncate the binary file in such a way so it
can be converted into a matrix. This will allow waterfall images to be
created even after a crash.

System should have the "truncate" command line utility installed which
is part of GNU GNU coreutils.

Corey Shields da4d89f2da waterfall fm_demod script
fm_demod script that also writes waterfall data (credit to surligas, I'm just committing)

Also FFT needs to be added to CMakeLists.txt to build in some conditions.

Manolis Surligas ce8d54eb40 Improve the generic FM demodulator
The FM demodulator now supports a variaty of hardware setups and saves
the WAV file for further processing. A set of command line arguments can
control most of the flowgraph internals, such as the wav file name and
storage path e.t.c.
