Retrieves a weighing scale 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 weighing scale sensor is online at the time it is invoked. The returned object is nevertheless valid. Use the method YWeighScale.isOnline() to test if the weighing scale sensor is indeed online at a given time. In case of ambiguity when looking for a weighing scale 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 weighing scale sensor |
- Returns
- a YWeighScale object allowing you to drive the weighing scale sensor.

Starts the enumeration of weighing scale sensors currently accessible. Use the method YWeighScale.nextWeighScale() to iterate on next weighing scale sensors.
- Returns
- a pointer to a YWeighScale object, corresponding to the first weighing scale sensor currently online, or a NULL pointer if there are none.
