I had some responses from people wanting to know more about the NEW DS18B20, unfortunately I lost those names so I'm sending the contact to everyone. Chris is the Product Manager at Dallas. Chris Beaudoin [mailto:Chris.Beaudoin@dalsemi.com] I still need C Libraries for the DS1820, I've searched the PIC archives and only found Assembly Libraries.
