This library is intended for Adafruit CircuitPython's API.  For a library compatible with MicroPython machine API see this `library <https://github.com/adafruit/micropython-adafruit-ht16k33>`_.\n\n    #. This library does not work with the Trellis 4x4 LED+Keypad board. For that product use: `CircuitPython Trellis Library <https://github.com/adafruit/Adafruit_CircuitPython_Trellis/releases/latest>`_\n\nDependencies\n=============\nThis driver depends on:\n\n* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_\n* `Bus Device <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>`_\n\nPlease ensure all dependencies are available on the CircuitPython filesystem.\nThis is easily achieved by downloading\n`the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>`_.\n\nUsage Example\n=============\n\n.. code-block :: python\n\n    # Import all board pins and bus interface.\n    import board\n    import busio\n\n    # Import the HT16K33 LED matrix module.\n    from adafruit_ht16k33 import matrix\n\n    # Create the I2C interface.\n    i2c = busio.I2C(board.SCL, board.SDA)\n\n    # Create the matrix class.\n    # This creates a 16x8 matrix:\n    matrix = matrix.Matrix16x8(i2c)\n    # Or this creates a 8x8 matrix:\n    #matrix = matrix.Matrix8x8(i2c)\n    # Or this creates a 8x8 bicolor matrix:\n    #matrix = matrix.Matrix8x8x2\n    # Finally you can optionally specify a custom I2C address of the HT16k33 like:\n    #matrix = matrix.Matrix16x8(i2c, address=0x70)\n\n    # Clear the matrix.\n    matrix.fill(0)\n\n    # Set a pixel in the origin 0,0 position.\n    matrix[0, 0] = 1\n    # Set a pixel in the middle 8, 4 position.\n    matrix[8, 4] = 1\n    # Set a pixel in the opposite 15, 7 position.\n    matrix[15, 7] = 1\n    matrix.show()\n\n    # Change the brightness\n    matrix.brightness = 8\n\n    # Set the blink rate\n    matrix.blink_rate = 2\n\n\nContributing\n============\n\nContributions are welcome! Please read our `Code of Conduct\n<https://github.com/adafruit/Adafruit_CircuitPython_HT16K33/blob/master/CODE_OF_CONDUCT.md>`_\nbefore contributing to help this project stay welcoming.\n\nBuilding locally\n================\n\nTo build this library locally you'll need to install the\n`circuitpython-build-tools <https://github.com/adafruit/circuitpython-build-tools>`_ package.\n\n.. code-block:: shell\n\n    python3 -m venv .env\n    source .env/bin/activate\n    pip install circuitpython-build-tools\n\nOnce installed, make sure you are in the virtual environment:\n\n.. code-block:: shell\n\n    source .env/bin/activate\n\nThen run the build:\n\n.. code-block:: shell\n\n    circuitpython-build-bundles --filename_prefix adafruit-circuitpython-ht16k33 --library_location .\n\nSphinx documentation\n-----------------------\n\nSphinx is used to build the documentation based on rST files and comments in the code. First,\ninstall dependencies (feel free to reuse the virtual environment from above):\n\n.. code-block:: shell\n\n    python3 -m venv .env\n    source .env/bin/activate\n    pip install Sphinx sphinx-rtd-theme\n\nNow, once you have the virtual environment activated:\n\n.. code-block:: shell\n\n    cd docs\n    sphinx-build -E -W -b html . _build/html\n\nThis will output the documentation to ``docs/_build/html``. Open the index.html in your browser to\nview them. It will also (due to -W) error out on any warning like Travis will. This is a good way to\nlocally verify it will pass.",
