Hi
I have used the DS1820 with 484 without any problems just take care of
the timing limits in the  datasheets. I have code for interfacing with
three different DS1820 att the same time and display it on a LCD. I
don't have it with me right now but i can send it to you if you
want.just send me a mail. If you have an oscilloscope try to check if
you have right signals out.
