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.
Installing from PyPI¶
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:
pip3 install adafruit-circuitpython-trellism4
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-trellism4
To install in a virtual environment in your current project:
mkdir project-name && cd project-name python3 -m venv .env source .env/bin/activate pip3 install adafruit-circuitpython-trellism4
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
