DS1825 Programmable Resolution 1-Wire Digital Thermometer With 4-Bit ID
SUGGESTED PROCEDURE FOR BUILDING CROSS-REFERENCE TABLE
This procedure uses the Search ROM command to find all DS1825s on the one-wire bus (16 maximum) and then
reads each configuration register to match the ROMIDs to the hard-wired addresses.
