The MSPM0 series microcontroller (MCU) portfolio offers a wide variety of 32-bit MCUs with ultra-low power and integrated analog and digital peripherals for sensing, measurement, and control applications. Reducing power consumption while performing complex real-time applications presents a major challenge for the recent embedded applications. This article was created to build a simple framework to help developers quickly setup the communication between MSPM0 and BQ769x2. Currently, the MSPM0 L series and G series are supported, and sample code is provided based on LP-MSPM0G3507 and LP-MSPM0L1306 LaunchPad™.
