AUTELCompass

class AUTELCompass​

describe：This class defines information about magnetometers.

@protocol AUTELCompass <NSObject>

property heading​

@property(nonatomic, readonly) double heading;

describe：This property indicates the direction of compass from –π to π. Sets 0 as north, -π/2 as west, π/2 as ease, π or –π as south. The value of heading equals to the value of AUTELMCSystemState.attitude.yaw。

property hasError​

@property(nonatomic, readonly) BOOL hasError;

describe：This property describes whether the compass has error or not. If Yes, the compass need calibration. The value of hasError equals to AUTELMCSystemState.isCompassError

property isCalibrating​

@property(nonatomic, readonly) BOOL isCalibrating;

describe：Whether or not the compass is in calibrating.

property calibrationStatus​

@property(nonatomic, readonly) AUTELCompassCalibrationStatus calibrationStatus;

describe：If isCalibration equals to Yes, this property indicates the status of calibration. AUTELCompassCalibrationStatus

Call startCalibrationWithCompletion method to trigger calibration mode. The order of calibration status is : AUTELCompassCalibrationNone -> AUTELCompassCalibrationStep1 -> AUTELCompassCalibrationStep2 -> AUTELCompassCalibrationCalculating -> AUTELCompassCalibrationSucceeded/AUTELCompassCalibrationFailed -> AUTELCompassCalibrationNone. The value of this property equals to AUTELMCSystemState.compassCalibrationStatus.

property compassInterferenceLevel​

@property(nonatomic, readonly) AUTELCompassInterferenceLevel compassInterferenceLevel;

describe：The level of magnetic interference.

The value of this property equals to AUTELMCSystemState.compassInterferenceLevel . When compassInterferenceLevel is AUTELCompassInterferenceLevel4, hasErorr property sets to Yes.

method startCalibrationWithCompletion​

- (void)startCalibrationWithCompletion:(AUTELCompletionBlock)block;

describe：Invoke this method to start compass calibration.

This method can be invoked when motors are on and returns AUTELSDKFlightControllerErrorMotorWorking error.

input parameter：

block：completionBlock. AUTELCompletionBlock
