DFRobot_BMI160

• 中文

The BMI160 is a highly integrated, low power inertial measurement unit (IMU) that provides precise acceleration and angular rate (gyroscopic) measurement.
The BMI160 contains 16 bit digtial,triaxial accelerometer and 16 bit digital, triaxial gyroscope.
This example is for BMI160 sensor and it oprated via Arduino I2C.

Summary

Provide an Arduino library to control the bmi160 to get accel, gyro 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
