This library will allow you to control the LEDs and read button presses on the Adafruit Trellis Board. It will work with a single Trellis board, or with a matrix of up to 8 Trellis boards.
For more details, see the Adafruit Trellis Learn Guide.
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-trellis
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-trellis
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-trellis
See examples/trellis_simpletest.py for full usage example.
import time import busio from board import SCL, SDA from adafruit_trellis import Trellis # Create the I2C interface i2c = busio.I2C(SCL, SDA) # Create a Trellis object for each board trellis = Trellis(i2c) # 0x70 when no I2C address is supplied # Turn on every LED print('Turning all LEDs on...') trellis.led.fill(True) time.sleep(2) # Turn off every LED print('Turning all LEDs off...') trellis.led.fill(False) time.sleep(2)
