By using the DS185x Evaluation Kit (DS185XEVKIT) and its associated software, you can program the DS185x family of devices through their I2C serial interface. The DS185x devices have internal EEPROM that is used for configuring device settings, as general-purpose memory, and as Lookup tables for calibration. To ease the programming of the tables, the software’s File tab lets you upload a correctly formatted text file into the memory. This application note explains the formatting required for the Lookup tables, and other precautions to take while using this feature of the DS185XEVKIT software.
