BMX160-Arduino

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.

DFRobot_BMX160 Library for Arduino

Provide an Arduino library to control the bmx160 to get acell, gyro and step counter, via I2C communication.

Summary

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

Installation

To use this library, first download the library file, paste it into the \Arduino\libraries directory, then open the examples folder and run the demo in the folder.

Methods

/*
 * @brief get the magn, gyro and accel data 
 * @param pointer to store the data: &Omagn, &Ogyro, &Oaccel.
 */
