GNU Radio Companion (GRC) is a graphical tool for creating GNU Radio signal flowgraphs.

Section 1 gnuradio bookworm source

Summary

gnuradio-companion (GRC) is the graphical editor for GNU Radio, where you build software-defined radio and signal-processing systems by wiring together signal-processing blocks into a flowgraph. When you run a flowgraph, GRC generates the corresponding Python code that creates the GUI and connects the blocks. Use it to design SDR and DSP applications visually instead of writing the Python by hand.

Tip: GRC is mainly a point-and-click GUI tool, so most of your work happens inside the application rather than on the command line.

GNURADIO-COMPANION

NAME

gnuradio-companion - GNU Radio Companion (GRC) is a graphical tool for creating GNU Radio signal flowgraphs.

SYNOPSIS

gnuradio-companion [options] [flowgraphs]

DESCRIPTION

GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software-defined radios and signal-processing systems. The GNU Radio applications themselves are generally known as "flowgraphs", which are a series of signal processing blocks connected together, thus describing a data flow.

gnuradio-companion is effectively a Python code-generation tool. When a flowgraph is "compiled" in GRC, it generates Python code that creates the desired GUI windows and widgets, and creates and connects the blocks in the flowgraph.

OPTIONS

flowgraphs Invoke the program with one or more existing flowgraphs.
-h, --help

show a help message and exit.

--log

defines the level of logging output.

gnuradio-companion my_flowgraph.grc

Open one or more existing flowgraph files directly.

gnuradio-companion --help

Show the help message and exit.

gnuradio-companion --log info

Set the level of logging output (use the --log option to control verbosity).
