CircuitPython library Trellis M4 Express.

Project description

Introduction

Documentation Status Discord Build Status Code Style: Ruff

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

Dependencies

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 .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:

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
