Every device on 1-Wire network has in its internal EEPROM a unique serial number that has to be known to the host.

Otherwise the host can not find the device and communicate.

On Maxim site there is an application note about a way to automatically find the devices on the local 1-wire network. SO every time your controller powers up, it makes an device scan and stores the found ID's or serial numbers.


The second method is to find the serial numbers by your self and store them in the internl EEPROM of the controller.


AN187, is the Note that describes the method
