We use the dallas S/N and temp sensor devices to ID our boards at OSU-ISL.
For HPSDR OZY we could steal one of the serial ports from the FX2 and
use a DS2480B to interface to the 1-Wire bus. That way we would not
have to generate the 1-Wire timing in the FX2 or FPGA. The FX2
firmware would just set up the serial port and read the 1-Wire bus for
configuration.
