Magnetometer sample

Shows how to use the Magnetometer class.

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.

The sample asks you to choose an magnetometer.

After choosing your magnetometer, you can choose one of these scenarios:

  • Magnetometer data events
  • Poll magnetometer readings

Magnetometer Data Events

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

Poll Magnetometer Readings

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

Magnetometer data events batching

When you choose the Enable button for the Data Events option, the app begins streaming magnetometer readings. The readings may be delivered in batches if the device supports data batching.

  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
