OneWire.DataPath (PROP) ¶ PROPERTY DataPath : STRING This property returns the path in the file system that contains the data
OneWire.ID (PROP) ¶ PROPERTY ID : OneWireUniqueID Gets or sets the device ID
OneWire.SetIDFromString (METH) ¶ METHOD SetIDFromString : BOOL allows to set the device ID with a string, that needs to have the format XX-AABBCCDDEEFF return value TRUE indicates that the setting was successful. InOut: Scope Name Type Return SetIDFromString BOOL Input sID STRING
OneWire.SetMasterInstance (METH) ¶ METHOD SetMasterInstance : BOOL with this method the internal pointer to the master device can be set. note: this method can only be applied when the slave device is not part of the device tree (where all this action is done automatically), but manually instanciated. Then, it must be linked to the master instance with this function. InOut: Scope Name Type Return SetMasterInstance BOOL Input pMaster POINTER TO OneWireMaster
