Description:
BQ-BATTERY-PROGRAMMER-SW software development kit (SDK) is a collection of robust software command line tools that assist with the process of programming, testing, or assembling packs that use TI Battery management products. The executables in this software work with the MKST-3P-ALT-EV2300 MKS Technology alternative for EV2300 communications transceiver. The executables work with a single station but can be extended to multiple stations by using additional software and GUI from MKS Technology Inc. . Support for multiple stations is not included in this software.
There are multiple executables in the download, usually one per family of products. Older products such as BQ20xxx and BQ30xxx are also supported. Examples using the C++ programming language API and Python® programming language are provided for custom development.

3. The executables, C API and Python API files can be found in the install location
4. Run the command line executable without arguments to get usage help. Refer to Readme.txt in the install folder for more information and how to get help using the command line.
bq27z855 v0.06 build 7
BQ27Z855-FW is a firmware-only release that can be flashed onto any existing BQ27Z855 hardware. The firmware incorporates the patented Dynamic Z Track™ technology to create a pack-based solution that provides a rich array of features for gas gauging, protection, and authentication for 1-series cell Li-ion and Li-polymer battery packs.
BQ27Z855-FW includes integrated linear charger functionality to manage linear charging during Charge mode and ideal diode during Discharge mode. Using its integrated high-performance analog peripherals, BQ27Z855-FW measures and maintains an accurate record of available capacity, voltage, current, temperature, and other critical parameters in Li-ion batteries and reports this information to the system host controller over an I2C compatible interface. SHA-1, SHA-256, and ECC authentication, with secure memory for authentication keys, enables identification of genuine battery packs.
