Support for the ADS1x15 series of analog-to-digital converters. Available in 12-bit (ADS1015)
and 16-bit (ADS1115) versions.

Installation & Dependencies
===========================

This driver depends on:

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

Please ensure all dependencies are available on the CircuitPython filesystem.
This can be most easily achieved by downloading and installing
`the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>`_ on
your device.

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-ads1x15/>`_. To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-ads1x15

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

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-ads1x15

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-ads1x15

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

Single Ended
------------

.. code-block:: python

    import time

    import board

    from adafruit_ads1x15 import ADS1015, AnalogIn, ads1x15

    # Create the I2C bus
    i2c = board.I2C()

    # Create the ADC object using the I2C bus
    ads = ADS1015(i2c)

    # Create single-ended input on channel 0
    chan = AnalogIn(ads, ads1x15.Pin.A0)

    # Create differential input between channel 0 and 1
    # chan = AnalogIn(ads, ads1x15.Pin.A0, ads1x15.Pin.A1)

    print("{:>5}\t{:>5}".format("raw", "v"))

    while True:
        print("{:>5}\t{:>5.3f}".format(chan.value, chan.voltage))
        time.sleep(0.5)
