Documentation and Soapy Sdr source

FM Receiver App – Week 12 and 13 Update

We’re coming to an end and these 2 weeks progress we’re documenting and fixing small bugs. Week 13s progress was the following topics:

1. Improve Documentations, READMEs in each directory along with mkdocs github page
2. Use soapy SDR source instead of osmocom

Documentation

Its time to wrap things up and document my FM application, I added a README file in each directory that explains the files and function of each directory; making it easier for new contributors to understand the project structure. I also created a mkdocs web page with in depth tutorial that explains each concept that i implemented in the project.

SOAPY SDR source

The SoapySDR Source block is deprecated, but the soapy_custom_source block is not. I updated my code to use soapy_custom_source in order to avoid the additional dependencies of the Osmocom library. In addiction, since I am already using the SoapySDR Python bindings to detect connected devices, it made sense to use the soapy_custom_source block as well.

I have also noticed that there is no documentation for this block, maybe I need to contribute to the GNU Radio Docs.

End

Finally, this project has come to an end, there are plenty of suggested improvements that I might work on before the final submission

1. Allow Sample Rate Change
2. Improve FM detection logic
3. Calculate Station strength and display it
