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 library provides basic support for configuring functions and reading data.

• Product Repository - Product repository for the RAKWireless RAK12034 module.
• Documentation - Documentation and Quick Start Guide for the RAK12034 module.

In Arduino IDE, open Sketch->Include Library->Manage Libraries then search for RAK12034 .

In PlatformIO open PlatformIO Home, switch to libraries and search for RAK12034 . Or install the library project dependencies by adding:

lib_deps = rakwireless/RAK12034-BMX160 library

into platformio.ini

For manual installation, download the archive, unzip it and place the RAK12034-BMX160 folder into the library directory. In Arduino IDE this is usually /libraries/ In PlatformIO this is usually <user/.platformio/lib>

The library provides an BMX160 class that allows you to communicate with BMX160 and get the chip data. Check out the examples how to get the chip data.

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

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.
