Dear PicList members

I have once read the DS1820 with success, but recently tried it again...
I get a presence pulse as it should and when I ask the Dallas chip for a
temperature reading it gives me a constant reading of 16 Deg C no matter
what I do...

In fact I am using exactly the same source code as last time and my
connections are correct.

Can someone help before I use I cutting tourch to test the Dallas range
between 2000 and 3000 Deg C.

Kindest Regards

Francois Robbertze
