SparkFun BMA400 Arduino Library


SparkFun Triple Axis Accelerometer Breakout - BMA400 (Qwiic)	SparkFun Micro Triple Axis Accelerometer Breakout - BMA400 (Qwiic)

This library provides an easy way to control the BMA400 3-axis accelerometer. Each axis has 12-bit resolution, and supports ranges of 2g up to 16g. It also includes a number of interrupt features, including motion detection, orientation detection, tap detection, and step counting. The sensor also includes filtering, and an on-board FIFO buffer can be used to store measurements for more efficient burst reading of data.

This library implements Bosch's BMA400 API in an Arduino-friendly way. All functions return error codes to indicate the result of each operation, where BMA400_OK (0) indicates success. Most examples ignore the error codes to reduce clutter, but an example is included to demonstrate error handling techniques.
