Field Documentation

TInt TSensrvRotationData::iDeviceRotationAboutXAxis
 
  • Item name: Rotation about x-axis
    • Item Index: 1
    • Description: Positive rotation in Cartesian coordinate system about the x-axis.

If the value cannot be defined it is set to KSensrvRotationUndefined.

TInt TSensrvRotationData::iDeviceRotationAboutYAxis
 
  • Item name: Rotation about y-axis
    • Item Index: 2
    • Description: Positive rotation in Cartesian coordinate system about the y-axis.

If the value cannot be defined it is set to KSensrvRotationUndefined.

TInt TSensrvRotationData::iDeviceRotationAboutZAxis
 
  • Item name: Rotation about z-axis
    • Item Index: 3
    • Description: Positive rotation in Cartesian coordinate system about the z-axis.

If the value cannot be defined it is set to KSensrvRotationUndefined.

TTime TSensrvRotationData::iTimeStamp
 
  • Item name: Sampling time.
  • Item Index: 0
  • Description: Timestamp for a sample
const TSensrvChannelDataTypeId TSensrvRotationData::KDataTypeId = 0x10205089 [static]
 

Channel data type Id number.

const TInt TSensrvRotationData::KSensrvRotationUndefined = -1 [static]
 

Rotation axis value equals -1 when it cannot be defined.

The undefined situation varies depending on the sensor type. In the case of an accelerometer, the rotation value cannot be defined when the corresponding axis is parallel to the gravitational force or the device is in motion. In the case of a magnetometer, there are difficulties in measuring values, when the axis is parallel to the magnetic field.
