DFRobot_BMX160

• 中文版

The BMX160 is a highly integrated, low power 9-axis sensor that provides precise acceleration and angular rate (gyroscopic) and geomagnetic measurement in each spatial direction.
The BMX160 contains 16 bit digtial,triaxial accelerometer 16 bit digital, triaxial gyroscope and geomagnetic sensor.
This example is for BMX160 sensor and it oprated via Arduino I2C.

Summary

Provide an Arduino library to control the bmx160 to get magnetometer accelerometer, gyroscope and step counter, via I2C communication.

Installation

There are two ways to use the library:

1. Open the Arduino IDE, search for "DFRobot_BMX160" in Tools --> Manager Libraries on the status bar, and install the library.
2. First download the library file, paste it into the \Arduino\libraries directory, then open the examples folder and run the demo in that folder.

Methods
