MPU6050_tockn

Arduino library for easy communicating with the MPU6050

Usage

You can see example sketch.

If you want to get data of MPU6050, you must execute update() method before get method.
update() will get all data of MPU6050, and calculating angle by accelerometer, gyroscope and complementary filter.

Complementary filter

update() method calculate angle by accelerometer and gyroscope using complementary filter.
Those two coefficients determined by constructor.
Default coefficient of accelerometer is 0.02, gyroscope is 0.98.
filtered_angle = (0.02 * accel) + (0.98 * gyro)

example

If you want to set 0.1 to accelerometer coefficient and 0.9 to gyroscope coefficient, your code is
MPU6050 mpu6050(Wire, 0.1, 0.9);

Auto calibration

If you use calcGyroOffsets() in setup(), it will calculate calibration of the gyroscope, and the value of the gyroscope will calibrated.
DO NOT MOVE MPU6050 during calculating.

#include <MPU6050_tockn>
#include <Wire.h>

MPU6050 mpu6050(Wire);

void setup(){
  Wire.begin();
  mpu6050.begin();
  mpu6050.calcGyroOffsets();
}

If you use calcGyroOffsets(true) in setup(), you can see state of calculating calibration in serial monitor.

#include <MPU6050_tockn>
#include <Wire.h>

MPU6050 mpu6050(Wire);

void setup(){
  Serial.begin(9600);
  Wire.begin();
  mpu6050.begin();
  mpu6050.calcGyroOffsets(true);
}

Serial monitor:

Calculate gyro offsets
DO NOT MOVE MPU6050.....
Done!
X : 1.45
Y : 1.23
Z : -1.32
Program will start after 3 seconds

If you know offsets of gyroscope, you can set them by setGyroOffsets(), and you don't have to execute calcGyroOffsets(), so you can launch program quickly.

example

#include <MPU6050_tockn>
#include <Wire.h>

MPU6050 mpu6050(Wire);

void setup(){
  Serial.begin(9600);
  Wire.begin();
  mpu6050.begin();
  mpu6050.setGyroOffsets(1.45, 1.23, -1.32);
}
