SDR Device and Code Documenting

FM Receiver App – Week 10 Update

This week I made progress on the following topics:

1. Fixed toggle issue during scanning
2. Added SDR Config Manager
3. Mkdocs Server
4. Debugged the Config Manager

Fixed toggle issue during scanning

Previously, during scanning the toggle of the listen button would switch and it would appear checked when its not really checked, to fix this issue I edited the fm player function to set checkable according to the status of the mute.

    def fm_player(self):
        """Toggle volume on/off"""
        if self.mute: # is muted --> unmute
            self.mute_button.setText("Stop Listening")
            self.mute_button.setChecked(True)
            self.set_mute(False)
        else:   # not muted --> mute
            self.mute_button.setText("Listen")
            self.mute_button.setChecked(False)
            self.set_mute(True)

This ensures the listen button is checked only when listening

SDR Config Manager

The application now allows the user to choose a connected SDR device before proceeding, this avoid stack crash when the app doesnt detect the sdr device

It automatically scans for avaliable sdr devices, and gets the serial of the detected device which is later used in the flowgraph as a parameter.

Mkdocs Server

For the documentation part, I have added a docstring to every function in the main window, I have also added type hints for parameters. I also learned mkdocs to serve a web app on github pages. You can acess the page from here docs
