Constructor Details

ADIS16448_IMU

public ADIS16448_IMU()

ADIS16448_IMU

public ADIS16448_IMU(ADIS16448_IMU.IMUAxis yaw_axis, SPI.Port port, ADIS16448_IMU.CalibrationTime cal_time)

Parameters:

yaw_axis - The axis that measures the yaw

port - The SPI Port the gyro is plugged into

cal_time - Calibration time

Method Details

isConnected

public boolean isConnected()

toUShort

public static int toUShort(int... buf)

configDecRate

public int configDecRate(int m_decRate)

configCalTime

public final int configCalTime(ADIS16448_IMU.CalibrationTime new_cal_time)

Configures calibration time

Parameters:

new_cal_time - New calibration time

Returns:

1 if the new calibration time is the same as the current one else 0

calibrate

public void calibrate()

Calibrate the gyro. It's important to make sure that the robot is not moving while the calibration is in progress, this is typically done when the robot is first turned on while it's sitting at rest before the match starts.

setYawAxis

public int setYawAxis(ADIS16448_IMU.IMUAxis yaw_axis)

Sets the yaw axis

Parameters:

yaw_axis - The new yaw axis to use

Returns:

1 if the new yaw axis is the same as the current one else 0.

reset

public void reset()

close

public void close()

Delete (free) the spi port used for the IMU.

Specified by:

close in interface AutoCloseable
