    Linux code to communicate with our gauges can be found here:

    http://processors.wiki.ti.com/index.php/Linux/Android_Software_Solutions_for_TI_Single-cell_Gas_Gauges

    It includes a driver for reading information from the fuel gauge and also a tool for writing the configuration to the fuel gauge and logging purposes.

    Is your problem the accuracy of the SOC reported by the fuel gauge or is your problem developing a driver to communicate with the gauge?  Note that you must properly configure the gauge to match your battery profile and system requirements before you can get accurate SOC.  This includes determining the correct battery profile (chemID), running a learning cycle on a sample pack to optimize the capacity and resistance profiles, then finalizing all of the dataflash configuration parameters to suit your system requirements.  Then you would save a golden dataflash file which would be used to configure all your gauges in production.  The easiest way to get your chemID and optimized pack parameters is to run a single discharge cycle and upload the data to the Gauge Parameter Calculator (GPC) tool on TI.com.  To configure the other basic parameters you can use the Parameter Q&A plugin in bqStudio.
