Function Documentation

int CPhidgetPHSensor_create

(

CPhidgetPHSensorHandle *

phid

)

Creates a Phidget PHSensor handle.

Parameters:

phid

A pointer to an unallocated Phidget PHSensor handle.

int CPhidgetPHSensor_getPH	(	CPhidgetPHSensorHandle	phid,
		double *	ph
	)

Gets the sensed PH.

Parameters:

	phid	An attached phidget ph sensor handle.
	ph	The PH.

int CPhidgetPHSensor_getPHMax	(	CPhidgetPHSensorHandle	phid,
		double *	max
	)

Gets the maximum PH that the sensor could report.

Parameters:

	phid	An attached phidget ph sensor handle.
	max	The maximum PH.

int CPhidgetPHSensor_getPHMin	(	CPhidgetPHSensorHandle	phid,
		double *	min
	)

Gets the minimum PH that the sensor could report.

Parameters:

	phid	An attached phidget ph sensor handle.
	min	The minimum PH.

int CPhidgetPHSensor_set_OnPHChange_Handler	(	CPhidgetPHSensorHandle	phid,
		int(*)(CPhidgetPHSensorHandle phid, void *userPtr, double ph)	fptr,
		void *	userPtr
	)

Set a PH change handler. This is called when the PH changes by more then the change trigger.

Parameters:

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

int CPhidgetPHSensor_getPHChangeTrigger	(	CPhidgetPHSensorHandle	phid,
		double *	trigger
	)

Gets the PH change trigger.

Parameters:

	phid	An attached phidget ph sensor handle.
	trigger	The change trigger.

int CPhidgetPHSensor_setPHChangeTrigger	(	CPhidgetPHSensorHandle	phid,
		double	trigger
	)

Sets the PH change trigger.

Parameters:

	phid	An attached phidget ph sensor handle.
	trigger	The change trigger.

int CPhidgetPHSensor_getPotential	(	CPhidgetPHSensorHandle	phid,
		double *	potential
	)

Gets the sensed potential.

Parameters:

	phid	An attached phidget ph sensor handle.
	potential	The potential.

int CPhidgetPHSensor_getPotentialMax	(	CPhidgetPHSensorHandle	phid,
		double *	max
	)

Gets the maximum potential that can be sensed.

Parameters:

	phid	An attached phidget ph sensor handle.
	max	The maximum potential.

int CPhidgetPHSensor_getPotentialMin	(	CPhidgetPHSensorHandle	phid,
		double *	min
	)

Gets the minimum potential that can be sensed.

Parameters:

	phid	An attached phidget ph sensor handle.
	min	The minimum potential.

int CPhidgetPHSensor_setTemperature	(	CPhidgetPHSensorHandle	phid,
		double	temperature
	)

Sets the temperature to be used for PH calculations.

Parameters:

	phid	An attached phidget ph sensor handle.
	temperature	The temperature (degrees celcius). By default this is 20.
