BMI160-Arduino

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.

DFRobot_BMI160 Library for Arduino

Provide an Arduino library to control the bmi160 to get acell, gyro and step counter, via I2C communication.

Summary

Provide an Arduino library to control the bmi160 to get acell, 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

#include <DFRobot_BMI160.h>

/*
 * @brief set the i2c addr and init the i2c.
 * @param i2c_addr  bmi160 i2c addr
 *     0x68: connect SDIO pin of the BMI160 to GND which means the default I2C address
 *     0x69: set I2C address by parameter
 * @return BMI160_OK(0) means success
 */
int8_t I2cInit(int8_t i2c_addr);

/*
 * @brief set interrupt number and choosing step detector interrupt
 * @param choose int1 or int2
 * @return BMI160_OK(0) means succse

/*
 * @brief set the step power model
 * @param type of model 
 * @return BMI160_OK(0) measn succse
 */
