Hi,
Created 2 examples for the Dallas Library:
UserDataWriteBatch.ino - assigns the same ID to all DS18B20 on the onewire bus.
This can be used to prepare DS18B20 for the next demo sketch.
UserDataDemo.ino - implements getTempByID(int ID) function.
This function uses a lookup table that maps individual addresses to ID's. This lookup table is initialized during setup. One should take care that every DS18B20 has an unique ID. This example needs 4 prepared DS18B20's
With this technique one can easily replace broken DS18B20's with one with the same ID preventing renumbering all sensors used in the code.
