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
