Function Documentation

int CPhidgetAccelerometer_create

(

CPhidgetAccelerometerHandle *

phid

)

Creates a Phidget Accelerometer handle.

Parameters:

phid

A pointer to an unallocated Phidget Accelerometer handle.

int CPhidgetAccelerometer_getAxisCount	(	CPhidgetAccelerometerHandle	phid,
		int *	count
	)

Gets the number of acceleration axes supported by this accelerometer.

Parameters:

	phid	An attached phidget accelerometer handle.
	count	The axis count.

int CPhidgetAccelerometer_getAcceleration	(	CPhidgetAccelerometerHandle	phid,
		int	index,
		double *	acceleration
	)

Gets the current acceleration of an axis.

Parameters:

	phid	An attached phidget accelerometer handle.
	index	The acceleration index.
	acceleration	The acceleration.

int CPhidgetAccelerometer_getAccelerationMax	(	CPhidgetAccelerometerHandle	phid,
		int	index,
		double *	max
	)

Gets the maximum accleration supported by an axis.

Parameters:

	phid	An attached phidget accelerometer handle.
	index	The acceleration index
	max	The maximum acceleration

int CPhidgetAccelerometer_getAccelerationMin	(	CPhidgetAccelerometerHandle	phid,
		int	index,
		double *	min
	)

Gets the minimum acceleraiton supported by an axis.

Parameters:

	phid	An attached phidget accelerometer handle.
	index	The acceleration index
	min	The minimum acceleraion

int CPhidgetAccelerometer_set_OnAccelerationChange_Handler	(	CPhidgetAccelerometerHandle	phid,
		int(*)(CPhidgetAccelerometerHandle phid, void *userPtr, int index, double acceleration)	fptr,
		void *	userPtr
	)

Sets an acceleration change event handler. This is called when the acceleration changes by more then the change trigger.

Parameters:

	phid	A phidget accelerometer handle.
	fptr	Callback function pointer.
	userPtr	A pointer for use by the user - this value is passed back into the callback function.

int CPhidgetAccelerometer_getAccelerationChangeTrigger	(	CPhidgetAccelerometerHandle	phid,
		int	index,
		double *	trigger
	)

Gets the change trigger for an axis.

Parameters:

	phid	An attached phidget accelerometer handle.
	index	The acceleration index
	trigger	The change trigger.

int CPhidgetAccelerometer_setAccelerationChangeTrigger	(	CPhidgetAccelerometerHandle	phid,
		int	index,
		double	trigger
	)

Sets the change trigger for an axis.

Parameters:

	phid	An attached phidget accelerometer handle.
	index	The acceleration index
	trigger	The change trigger.
