Usage

SpiConnectionSettings settings = new SpiConnectionSettings(0, 0)
{
    ClockFrequency = Adxl345.SpiClockFrequency,
    Mode = Adxl345.SpiMode
};

var device = SpiDevice.Create(settings);

// set gravity measurement range ±4G
using (Adxl345 sensor = new Adxl345(device, GravityRange.Range04))
{
    // read acceleration
    Vector3 data = sensor.Acceleration;

    //use sensor
}

Example

Hardware Required

• ADXL345
• Male/Female Jumper Wires

Circuit

• VCC - 3.3 V
• GND - GND
• CS - CS0(Pin24)
• SDO - SPI0 MISO(Pin21)
• SDA - SPI0 MOSI (Pin19)
• SCL - SPI0 SCLK(Pin23)

Code

SpiConnectionSettings settings = new SpiConnectionSettings(0, 0)
{
    ClockFrequency = Adxl345.SpiClockFrequency,
    Mode = Adxl345.SpiMode
};
var device = SpiDevice.Create(settings);

// Set gravity measurement range ±4G
using (Adxl345 sensor = new Adxl345(device, GravityRange.Range04))
{
    // loop
    while (true)
    {
        // read data
        Vector3 data = sensor.Acceleration;

        Console.WriteLine($"X: {data.X.ToString("0.00")} g");
        Console.WriteLine($"Y: {data.Y.ToString("0.00")} g");
        Console.WriteLine($"Z: {data.Z.ToString("0.00")} g");
        Console.WriteLine();

        // wait for 500ms
        Thread.Sleep(500);
    }
}
