Does anybody have advice on reliably·communicating with a·1-wire device 100 feet away·(using the bs2p).· I have·read contradictory information on the Dallas website about this.· Some application notes mention that a direct connection to·a microcontroller io pin is fine while others say it is insufficient for long distances.

Thanks for the help,
Frank···

    Here is a post from another thread that might give you a resource to look at:

    Hello Everyone,
    My book Embedded Systems Desktop Communications goes very heavy into the 1-Wire interface. I hve circuits in there that can get over 1,000 feet ona 1-Wire network leg. There are several chips out there from Maxim/Dallas that provide USB, Ethernet, and RS232/RS422 1-Wire interfaces. While I2C will work, you can't get the distance to go through an entire building. The 1-Wire Pot is also a very nice piece of work.

    Regards,
    Oliver
