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
