This high level library provides objects that represent Trellis M4 hardware.

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-trellism4/>`_. To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-trellism4

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

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-trellism4

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-trellism4

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

This example prints out the coordinates of a button each time it is pressed and released:

.. code-block:: python

     import time
     import adafruit_trellism4

     trellis = adafruit_trellism4.TrellisM4Express()

     current_press = set()
     while True:
         pressed = set(trellis.pressed_keys)
         for press in pressed - current_press:
             print("Pressed:", press)
         for release in current_press - pressed:
             print("Released:", release)
         time.sleep(0.08)
         current_press = pressed
