BMI160-Arduino

This driver is for BMI160 6DoF sensor breakout boards which are connected through the Arduino SPI. Derived from the Intel's CurieIMU driver for the Arduino/Genuino 101.

Intel's driver repository: https://github.com/01org/corelibs-arduino101/tree/master/libraries/CurieIMU

BMI160: https://www.bosch-sensortec.com/bst/products/all_products/bmi160

How to install

Copy all files of this project to the your Arduino IDE library folder.

Example:

cp ~/github/BMI160-Arduino ~/Documents/Arduino/libraries/

Get sensor board

You can find cheap breakout boards ($2~3 USD) on the eBay. Pin names may vary by board vendors. I have two variations of BMI160 breakout board. Screenshot

Wiring

SPI mode

You should connect some digital out pin to the CSB of the BMI160 and tell the number of the pin to the initialize method, begin(). Screenshot

I2C mode

You should connect SDO/SA0 pin of the BMI160 to GND for default I2C address or tell the I2C address to the initialize method, begin(). Screenshot

Code

#include <BMI160Gen.h>

const int select_pin = 10;
const int i2c_addr = 0x68;

void setup() {
  Serial.begin(9600); // initialize Serial communication
  while (!Serial);    // wait for the serial port to open

  // initialize device
  BMI160.begin(BMI160GenClass::SPI_MODE, select_pin);
  //BMI160.begin(BMI160GenClass::I2C_MODE, i2c_addr);
}

void loop() {
  int gx, gy, gz;         // raw gyro values

  // read raw gyro measurements from device
  BMI160.readGyro(gx, gy, gz);

  // display tab-separated gyro x/y/z values
  Serial.print("g:\t");
  Serial.print(gx);
  Serial.print("\t");
  Serial.print(gy);
  Serial.print("\t");
  Serial.print(gz);
  Serial.println();

  delay(500);
}

Other boards which have the same MCU might be work well.

You can’t perform that action at this time.
