After you have installed the component (see below), you will need to make sure that you have permission to execute the Python files. To do this, navigate to /sdr/bin/MyComponent and type:
$ chmod +x *.py
C++ components
For C++ components, within the generated your_component_name.cpp file you
may enter the code for processing data. Look for /*insert code here to do
work*/ within the process_data function. Editing the SPD file should not be
necessary. The installed executable file,
/sdr/bin/your_component_name, needs to be executable, but this should
be done by default.
