XMF-H EEPROM should be
flashed with OCC
calibration values. If it is
not, API will provide
uncalibrated Power value
and return value will
indicate Error.
6.1.5 Battery Management Library Usage
1. User needs to include the header file <battery_management.h> of the library into the
application source code.
2. User needs to initialize the library by calling the BatteryManagementInit() function.
[Once Init is successful, multiple APIs can be called before deinit.]
3. Call the relevant API from following list in Battery management Interface Table to perform
operation on Power management I2C interface.
4. De-initialize the library by calling the BatteryManagementDeInit().
5. Link the library while compiling the application by “-lbatterymanagement”.
