Configuring your setup
NOTE: Those steps are a First-time setup and have to be done again only if you change something in the code.
Configurator
To configure your setup, first thing is to run the Configurator.
The Configurator only runs in Windows. If you can't run Windows, you can do the same functions with the text-oriented Command Line Interface.
Command Line Interface (CLI)
If you are planning to use a GPS, you have to set up the magnetometers with the CLI.
