This high level library provides objects that represent Trellis M4 hardware.
This driver depends on:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.
This example prints out the coordinates of a button each time it is pressed and released:
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

Zip release files¶
To build this library locally you’ll need to install the circuitpython-build-tools package.
python3 -m venv .env source .env/bin/activate pip install circuitpython-build-tools
Once installed, make sure you are in the virtual environment:
Then run the build:
circuitpython-build-bundles --filename_prefix adafruit-circuitpython-trellism4 --library_location .
Sphinx is used to build the documentation based on rST files and comments in the code. First, install dependencies (feel free to reuse the virtual environment from above):
python3 -m venv .env source .env/bin/activate pip install Sphinx sphinx-rtd-theme
Now, once you have the virtual environment activated:
cd docs sphinx-build -E -W -b html . _build/html
This will output the documentation to
docs/_build/html. Open the index.html in your browser to
view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to
locally verify it will pass.
