# [WIP] MicroPython MPU-6886 I2C driver
The MPU-6886 is a 6-axis motion tracking device that combines a 3-axis gyroscope and a 3-axis accelerometer.
## Usage
Simple test with never ending loop.
```python
import utime
from machine import I2C, Pin
from mpu6886 import MPU6886
i2c = I2C(scl=Pin(22), sda=Pin(21))
sensor = MPU6886(i2c)
print("MPU6886 id: " + hex(sensor.whoami))
while True:
print(sensor.acceleration)
print(sensor.gyro)
print(sensor.temperature)
utime.sleep_ms(1000)
```
By default the library returns 3-tuple of X, Y, Z axis values for acceleration and gyroscope. Default units are `m/s^2`, `rad/s` and `°C`. It is possible to also get acceleration values in `g` and gyro values `deg/s`. See the example below.
```python
import utime
from machine import I2C, Pin
from mpu6886 import MPU6886, SF_G, SF_DEG_S
i2c = I2C(scl=Pin(22), sda=Pin(21))
sensor2 = MPU6886(i2c, accel_sf=SF_G, gyro_sf=SF_DEG_S)
print("MPU6886 id: " + hex(sensor.whoami))
while True:
print(sensor.acceleration)
print(sensor.gyro)
print(sensor.temperature)
utime.sleep_ms(1000)
```
More realistic example usage with timer. If you get `OSError: 26` or `i2c driver install error` after soft reboot do a hard reboot.
```python
import micropython
from machine import I2C, Pin, Timer
from mpu6886 import MPU6886
micropython.alloc_emergency_exception_buf(100)
i2c = I2C(scl=Pin(22), sda=Pin(21))
sensor = MPU6886(i2c)
def read_sensor(timer):
print(sensor.acceleration)
print(sensor.gyro)
print(sensor.temperature)
print("MPU6886 id: " + hex(sensor.whoami))
timer_0 = Timer(0)
timer_0.init(period=1000, mode=Timer.PERIODIC, callback=read_sensor)
```
