STSW-BAT001 open source driver for the STC3115
Aurelien Mazard
Introduction
The STC3115 open source driver is a ready-to-use, configurable software (STSW-BAT001) which
allows the STC3115 gas gauge IC to be rapidly integrated to the final system software. The driver is
split into five C language files and can be compiled with any operating system for any processor.
The STC3115 open source driver comes with a full API which uses simple input information to initialize
and control the STC3115 registers and RAM and return battery status information in a simple structure
to the system.
The open source driver is available for free to manage system requirements and to handle the
complexity of STC3115 initialization. It is intended only for example purposes.
This user manual describes the STC3115 open source driver (STSW-BAT001) package content,
capabilities, and correct usage. It also explains the step-by-step procedure to configure and integrate
the open source driver in a complete software architecture.
The figure below shows an overview of the STC3115 software driver architecture. No additional
software is needed to manage the STC3115.
