How to Program a Device Using the File Tab in
the DS185XEVKIT
By: Hrishikesh Shinde
Mar 20, 2006
Abstract: 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.

Figure 1 illustrates the File section of the DS185x evaluation kit (DS185XEVKIT) software. You use the
Gen Template and the Fill Device buttons to program a device. The Gen Template button is used first to
generate a template for importing into Microsoft Excel or any other spreadsheet program. This imported
file can be modified, saved, and then later uploaded into the device by using the Fill Device button.
