张高兴的 Windows 10 IoT 开发笔记：三轴数字罗盘 HMC5883L

This is a Windows 10 IoT Core project on the Raspberry Pi 2/3, coded by C#.

Attention

I don't know how to check the sensor data, so...But the direction looks good.

Connect

• SDA - Pin3
• SCL - Pin5
• VCC - 3.3/5V
• GND - GND

What Contains

In HMC5883L.cs file

/// <summary>
/// Initialize
/// </summary>
/// <returns></returns>
public async Task InitializeAsync();
/// <summary>
/// Read raw data from HMC5883L
/// </summary>
/// <returns>Raw data</returns>
public HMC5883LData ReadRaw();
/// <summary>
/// Calculate direction angle
/// </summary>
/// <param name="rawData">HMC5883LData</param>
/// <returns>Angle</returns>
public double RawToDirectionAngle(HMC5883LData rawData);
/// <summary>
/// Cleanup
/// </summary>
public void Dispose();

How to Use

• First, you need to create a HMC5883L object. After that you should call InitializeAsync() to initialize.

HMC5883L sensor = new HMC5883L(MeasurementMode.Continuous);
await sensor.InitializeAsync();

• Secondly

var data = sensor.ReadRaw();
double angle = sensor.RawToDirectionAngle(data);

• If you want to close the sensor, call Dispose().

sensor.Dispose();
