Hi all,
I was playing with some DS18B20 device at home and don't understand how to enter the identity of the one wire device. The Address attribute is mentioned in the documentation to be entered in decimal but my one wire device is additionnaly to the family code a 12 digit hex number which doesn't fit in the 10 digit decimal length of the Address attribute.
Am I missing somehting ?
I have tried entering the DataFile directly but it looks it tries anyway to initialize the pair family-Address:I put a fake number at the moment as the real won't fit

Thanks for your support
PS: I m working with a rpi proview package in v5.7

Hi Snarf,

You can try something like this.
Check in /sys/bus/... your detected one-wire device.....

Many moons ago I used a setup with around 10 pcs. DS18B2's. with around 1 sec. sample time.
What I remember the wire length can be pretty long. (10 meter????)

Can't remember the details. Sorry.

Thanks Marc

I thought I ve done exactly what you did but my init failed.

Hopefully comparing line per line with your setup I discovered that my DataFile name was incorrect so the mistake was me ...as usual

So thanks for your help, it forced me to tripple check my config which was wrong...
All clear now with same config as you except the one wire id of course
Bye
