You didnt supply any anyformation on what setup you have, what wiring, anything. I got this temp sensor working on my raspberry pi interface trough a gpio. It just worked pretty much right after connecting.
I do reading by | Code: | | cat /sys/bus/w1/devices/10-00080234149b/w1_slave |
where the number is the 1-wire address.
this might be of help http://webshed.org/wiki/RaspberryPI_DS1820 although you provided no details of your situation, so dont expect anything to be helpful. |
