CircuitPython driver for the Adafruit TCS3448 14-Channel Light / Color Sensor Breakout - STEMMA QT / Qwiic


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/6525>`_

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-tcs3448/>`_.
To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-tcs3448

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

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-tcs3448

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-tcs3448

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_tcs3448

Or the following command to update an existing version:

.. code-block:: shell

    circup update

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

.. code-block:: python

    import time
    import board
    from adafruit_tcs3448 import TCS3448

    i2c = board.I2C()
    sensor = TCS3448(i2c)

    CHANNEL_LABELS = [
        "FZ (450nm blue)",
        "FY (560nm yellow-green)",
        "FXL (596nm orange)",
        "NIR (855nm near-IR)",
        "VIS_TL_0 (clear top-left, cycle 1)",
        "VIS_BR_0 (clear btm-right, cycle 1)",
        "F2 (424nm violet-blue)",
        "F3 (473nm blue-cyan)",
        "F4 (516nm green)",
        "F6 (636nm red)",
        "VIS_TL_1 (clear top-left, cycle 2)",
        "VIS_BR_1 (clear btm-right, cycle 2)",
        "F1 (407nm violet)",
        "F7 (687nm deep red)",
        "F8 (748nm near-IR edge)",
        "F5 (546nm green-yellow)",
        "VIS_TL_2 (clear top-left, cycle 3)",
        "VIS_BR_2 (clear btm-right, cycle 3)",
    ]

    while True:
        readings = sensor.all_channels
        print("--- TCS3448 Channel Readings ---")
        for label, value in zip(CHANNEL_LABELS, readings):
            print(f"  {label}: {value}")
        print()
        time.sleep(1)
