Installing Libraries

To utilise the sensors on the Pytrack and Pysense, Pycom has written libraries to make reading to/from the various sensors accessible via an API. These libraries reside at the Pycom GitHub repository and the latest versions can be found under the releases page.

GitHub Repository

Download the repository as a .zip file, navigate to the correct device (Pysense/Pytrack), extract the files and then upload the desired files to the device in the instructions below.

Uploading the Libraries to a Device

These libraries should be uploaded to a device (LoPy, SiPy, WiPy 2.0, etc.) in the same process as a standard MicroPython library. The various .py files should be placed into the /lib folder on the device. For example, if using the Pysense and the user wishes to enable the only Accelerometer and the Light Sensor, they should place the following .py files into the device's /lib folder:

  • pysense.py
  • LIS2HH12.py
  • LTR329ALS01.py

Add as many or as few of the libraries that are required.

In addition to the Pysense or Pytrack specific libraries, you also need to upload the pycoproc.py file from the lib/pycoproc folder inside the libraries archive.

The Pytrack and Pysense boards behave the same as the Expansion Board. Sync, Run and upload code to Pycom modules via the Pymakr Plugin, in exactly the same process.

Importing/Using the Libraries

Once the libraries are uploaded to the device, they can be used/imported as a typical MicroPython library would be. For example, importing and using the light sensor on the Pysense:

from pysense import Pysense
from LTR329ALS01 import LTR329ALS01

py = Pysense()
lt = LTR329ALS01(py)

print(lt.light())
