Motion component

Component that provides motion data for the mobile device using its internal accelerometer

Version information

Library Version, Component Version, Date, Author, Info

Detailed description

Many mobile devices contain an internal accelerometer which can report the acceleration in each of the 3 perpendicular axes - x, y and z.

This component allows access to the data provided by this sensor (if available) and can report the data with/without the contribution of the gravity force at that time.

Examples

Graphing the accelerometer output

This example shows the acceleration in the 3 axes on a chart.

Using the Motion component with a callback

The is a similar example to above, but this one uses a callback function to retrieve the acceleration data on a regular basis.

Macro reference

GetAcceleration

	GetAcceleration
Returns the device's acceleration in the specified direction
- LONG	Axis
The axis to use (0=x, 1=y, 2=z)
- BOOL	Compensate
Set true to compensate for the effects of gravity
- FLOAT	Return

GetInterval

	GetInterval
Returns the interval at which the data is obtained from the device (in ms)
- LONG	Return

Initialise

	Initialise
Begins monitoring of the device's orientation information. Returns true if the device can provide orientation information.
- BOOL	Return

Property reference

	Properties
	Use Callback
Set true to use a callback that retrieves regular updates of the device accelerometer
