Accel

Python Library for NXP MMA8491Q 3-Axis Accelerometer & Tilt Sensor.

Python Library

Turta_Accel library is responsible for reading 3D acceleration and 3D tilt data from the MMA8491Q sensor.

Initialization

Add the following statement to the top of your Python code.

from turta_iothat3 import Turta_Accel

Then, create an instance of the AccelTiltSensor class.

accel = Turta_Accel.AccelTiltSensor()

Now you're ready to access the library by calling its instance.
