This library generates simple waveforms that can be used to generate different
type of audio signals.

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

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

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

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

.. code-block:: shell

    pip3 install adafruit-circuitpython-waveform

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

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-waveform

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-waveform

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

This example generates one wavelength of a 440hz sine wave when played at 16 kilosamples per second:

.. code-block:: python

    from adafruit_waveform import sine
    wave = sine.sine_wave(16000, 440)
