Introduction
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-trellism4To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-trellism4To 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-trellism4Usage 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 = pressedContributing
