DS18B20 onewire gotten this to work with 2.1.1
Is there anyone who has received a onewire to work with 10 dallas temp.
it works for me but I would like that it was fixed ID (children) of the sensors
Have a look at this thread. I think it contains the answer on your fixed ID (children) question.
I personally used the sample programs as provided with the MySensors lib with succes the get the DS18B20 onewire working.
A resistor 4k7 from +5VDC to the middle pin of the DS18B20 connected to D3 from the arduino and both outer pins of the DS18B20 connected to GND works perfect for me.
