Compass sample

Shows how to use the Windows.Devices.Sensors.Compass API.

Note: This sample is part of a large collection of UWP feature samples. If you are unfamiliar with Git and GitHub, you can download the entire collection as a ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.

This sample allows the user to view the compass reading as a magnetic-north and, depending on the installed sensor, a true-north value. You can choose one of three scenarios:

  • Compass data events
  • Poll compass readings
  • Sensor calibration

Compass Data Events

When you choose the Enable button for the Data Events option, the app begins streaming compass readings in real time.

Poll Compass Readings

When you choose the Enable button for the Polling option, the app will retrieve the sensor readings at a fixed interval.

Sensor Calibration

Allows the user to simulate sensor accuracy and demonstrates usage of the calibration bar.

Build the sample

  1. If you download the samples ZIP, be sure to unzip the entire archive, not just the folder with the sample you want to build.
  2. Start Microsoft Visual Studio 2017 and select File > Open > Project/Solution.
  3. Starting in the folder where you unzipped the samples, go to the Samples subfolder, then the subfolder for this specific sample, then the subfolder for your preferred language (C++, C#, or JavaScript). Double-click the Visual Studio Solution (.sln) file.
  4. Press Ctrl+Shift+B, or select Build > Build Solution.

Run the sample

The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.

Deploying the sample

  • Select Build > Deploy Solution.

Deploying and running the sample

  • To debug the sample and then run it, press F5 or select Debug > Start Debugging. To run the sample without debugging, press Ctrl+F5 or selectDebug > Start Without Debugging.
