This tutorial was written using GNU Radio v3.10.1.1.
Open a terminal and navigate to an appropriate directory, such as the home directory:
$ cd $HOME
GNU Radio comes packaged with gr_modtool, software used to create out-of-tree (OOT) modules. An OOT module can be thought of as a collection of custom GNU Radio blocks. Using gr_modtool, create an OOT module named ootmodule:
$ gr_modtool newmod ootmodule
The directory gr-ootmodule is created which contains all of the skeleton code for an OOT module, however it does not yet have any blocks.
Move into the directory:
$ cd gr-ootmodule
List all of the files and directories within the OOT module:
$ ls
The directory listing will be as follows:
apps/ cmake/ CMakeLists.txt docs/ examples/ grc/ include/ lib/ MANIFEST.md python/
now need to create a block within the OOT module. the block to be created will either add or subtract based on an input parameter.
$ gr_modtool add addSubtractSelector
Given a questionaire about how to define the block.
GNU Radio module name identified: ootmodule ('sink', 'source', 'sync', 'decimator', 'interpolator', 'general', 'tagged_stream', 'hier', 'noblock')
