Detailed Description

ID: adxrs610
Name: Gyro Breakout Board (300 Degrees/second)
Other Names: ADXRS610
Category: compass
Manufacturer: dfrobot

Connection: analog

The ADXRS610 is a MEMS based single axis gyroscope with a range of +/- 300 degrees/sec. It also incorporates a temperature sensing unit that can be used for advanced calibration.

This sensor returns an analog voltage proportional to the rotation about the Z-axis in degrees/sec. The temperature component returns a proportional analog values in degrees C.

This driver was developed using the DFRobot ADXRS610 Gyro Breakout board.

    // Instantiate a ADXRS610 sensor on analog pin A0 (dataout), and
    // analog A1 (temp out) with an analog reference voltage of
    // 5.0
    upm::ADXRS610 sensor(0, 1, 5.0);
    // set a deadband region around the zero point to report 0.0 (optional)
    sensor.setDeadband(0.015);
    // Every tenth of a second, sample the ADXRS610 and output it's
    // corresponding temperature and angular velocity
    while (shouldRun) {
        cout << "Vel (deg/s): " << sensor.getAngularVelocity() << endl;
        cout << "Temp (C): " << sensor.getTemperature() << endl;
        upm_delay_us(100000);
    }

Member Function Documentation

float getDataVolts ( )

Returns the voltage detected on the DATA analog pin

Returns: The detected voltage

Here is the caller graph for this function:

float getTemperatureVolts ( )

Returns the voltage detected on the TEMP analog pin

Returns: The detected voltage

Here is the caller graph for this function:

void setDeadband ( float deadband )

inline

This method allows you to specify a deadband region around the zero point of the gyro (at rest). This can be used as a primitive filter to ignore movment around the zero point.

Parameters

deadband The voltage around the zero point which will be ignored

Here is the caller graph for this function:

void setZeroPoint ( float zeroPoint )

inline

Set the zero point. This is the point measured and averaged when the sensor is not moving. It is set at construction time (averaged over a number of samples), but can be overridden here.

Parameters

zeroPoint The averaged zero point of the sensor at rest
