dm_applications

dm_apps.sh, dm_apps.ps1

Linux and Windows scripts to create a pyhton virtual environment for the applications, install the module dependencies, and clone the sourceforge repository.

Download the file to the desired parent folder and then use the -i option documented below to install.

K3JSE Deviation Meter application installer and launcher

Command line options
  -i Install applications - default folder: dm_applications
  -d Device serial port
  -m Run meter app
  -p Run plot app

Examples
  ./dm_app.ps1 -i prompt to remove existing folder and install
  ./dm_app.ps1 -d /dev/ttyACM1 -m  run meter on port /dev/ttyACM1
  ./dm_app.ps1 -d com6 -p  run plot app on port com6

Note that the script does not download the Windows .exe files from the sourceforge project files tab. If running from Windows you can skip the dm_apps.ps1 install and use the .exe files instead but they will load more slowly than the python modules. USe the -d option when running to specify the deviation meter serial port or create a Desktop shortcut with the -d option.

E.G. from a Windows terminal session:

  ./dm_meter -d COM3

dm_meter

Connects to the deviation meter and receives deviation and rf error data for display.

The application can also change the scale factor, save configuration settings, and reset to defaults.

dm_plot

requests raw data from the meter and display three charts

1. raw data plot
2. audio spectrum
3. band pass filter

The application can specify sample rate and sample size
