Function Documentation

YPressure* yFindPressure ( const string &  func )

inline

Retrieves a pressure sensor for a given identifier. The identifier can be specified using several formats:

• FunctionLogicalName
• ModuleSerialNumber.FunctionIdentifier
• ModuleSerialNumber.FunctionLogicalName
• ModuleLogicalName.FunctionIdentifier
• ModuleLogicalName.FunctionLogicalName

This function does not require that the pressure sensor is online at the time it is invoked. The returned object is nevertheless valid. Use the method YPressure.isOnline() to test if the pressure sensor is indeed online at a given time. In case of ambiguity when looking for a pressure sensor by logical name, no error is notified: the first instance found is returned. The search is performed first by hardware name, then by logical name.

If a call to this object's is_online() method returns FALSE although you are certain that the matching device is plugged, make sure that you did call registerHub() at application initialization time.

Parameters

func	: a string that uniquely characterizes the pressure sensor

Returns

a YPressure object allowing you to drive the pressure sensor.

Definition at line 213 of file yocto_pressure.h.

YPressure* yFirstPressure ( void  )

inline

Starts the enumeration of pressure sensors currently accessible. Use the method YPressure.nextPressure() to iterate on next pressure sensors.

Returns

a pointer to a YPressure object, corresponding to the first pressure sensor currently online, or a NULL pointer if there are none.
