CircuitPython driver for the Adafruit VCNL4200 Long Distance IR Proximity and Light Sensor


Dependencies
=============
This driver depends on:

* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
* `Bus Device <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>`_
* `Register <https://github.com/adafruit/Adafruit_CircuitPython_Register>`_

Please ensure all dependencies are available on the CircuitPython filesystem.
This is easily achieved by downloading
`the Adafruit library and driver bundle <https://circuitpython.org/libraries>`_
or individual libraries can be installed using
`circup <https://github.com/adafruit/circup>`_.

`Purchase one from the Adafruit shop <http://www.adafruit.com/products/6064>`_

Installing from PyPI
=====================

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
PyPI <https://pypi.org/project/adafruit-circuitpython-vcnl4200/>`_.
To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-vcnl4200

To install system-wide (this may be required in some cases):

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-vcnl4200

To install in a virtual environment in your current project:

.. code-block:: shell

    mkdir project-name && cd project-name
    python3 -m venv .venv
    source .env/bin/activate
    pip3 install adafruit-circuitpython-vcnl4200

Installing to a Connected CircuitPython Device with Circup
==========================================================

Make sure that you have ``circup`` installed in your Python environment.
Install it with the following command if necessary:

.. code-block:: shell

    pip3 install circup

With ``circup`` installed and your CircuitPython device connected use the
following command to install:

.. code-block:: shell

    circup install adafruit_vcnl4200

Or the following command to update an existing version:

.. code-block:: shell

    circup update

Usage Example
=============

.. code-block:: python

    import time
    import board
    import adafruit_vcnl4200

    i2c = board.I2C()

    # Initialize VCNL4200
    sensor = adafruit_vcnl4020.Adafruit_VCNL4200(i2c)

    while True:
        print(f"Proximity is: {sensor.proximity}")
        print(f"Ambient is: {sensor.lux}")
        time.sleep(0.1)
