4.1.4 Software

The software provides a command API and drivers that are capable of implementing the examples provided in BQ79631-Q1 Software Design Reference.

The example code only provides a control interface to the BQ79631-Q1 and does not provide any other communications interface to the outside world. The customer is expected to develop their own communication implementation. Examples of communications interfaces available to the TMS570 are SPI, CAN, or UART. For the TMS570 example code, UART is the communication protocol used between the microcontroller and BQ79631-Q1 device.

This firmware provided with this application note provides source code examples of the command sequences described in the BQ79631-Q1 Software Design Reference.

Importing a project into Code Composer Studio™: 1. Launch the provided file: BQ79631-Q1 Example Code 0.1 Installer.exe and extract files to the default path provided (C:\ti\bq79631-Q1 Example Code 0.1). 2. Launch Code Composer Studio (CCS): Start → Programs → Texas Instruments → Code Composer Studio v8 → Code Composer Studio v8 3. When it launches, CCS requests a workspace is selected, choose “C:\myWorkspace”. Once CCS loads, go to: Project → Import CSS Projects... → Select search-directory 4. In Select search-directory, browse to the folder: C:\ti\bq79631-Q1 Example Code 0.1 5. In Discovered projects:, check BQ79616-Q1 example code
