CircuitPython driver for the TCA9548A I2C Multiplexer.

Dependencies

=============

This driver depends on:

* `Adafruit CircuitPython `_

* `Bus Device `_

Please ensure all dependencies are available on the CircuitPython filesystem.

This is easily achieved by downloading

`the Adafruit library and driver bundle `_.

Installing from PyPI

====================

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from

PyPI `_. To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-tca9548a

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

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-tca9548a

To install in a virtual environment in your current project:

.. code-block:: shell

    mkdir project-name && cd project-name

    python3 -m venv .venv

    source .venv/bin/activate

    pip3 install adafruit-circuitpython-tca9548a

Usage Example

=============

.. code-block :: python

    # This example shows using TCA9548A to perform a simple scan for connected devices

    import board

    import adafruit_tca9548a

    # Create I2C bus as normal

    i2c = board.I2C()  # uses board.SCL and board.SDA

    # Create the TCA9548A object and give it the I2C bus

    tca = adafruit_tca9548a.TCA9548A(i2c)

    for channel in range(8):

        if tca[channel].try_lock():

            print("Channel {}:".format(channel), end="")

            addresses = tca[channel].scan()

            print([hex(address) for address in addresses if address != 0x70])

            tca[channel].unlock()
