hello

I am trying to build a digital temperature sensor using a DS1821 temp
sensor and a PIC16F628.
I am having trouble determining how I am supposed to talk to the
temperature sensor. I'm trying to go by the data sheet but I dont seem
to be getting an acknowledge at all. When I try to tell it to start
sending data I get nothing.
Does anyone have any idea where I could be going wrong. Or at least a
sample program so I can see what its supposed to look like on a cro.

cheers
Ryan
