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-is31fl3731
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-is31fl3731
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-is31fl3731
Usage Example¶
Matrix:
from adafruit_is31fl3731.matrix import Matrix
import board
import busio
with busio.I2C(board.SCL, board.SDA) as i2c:
display = Matrix(i2c)
display.fill(127)
Charlie Wing:
from adafruit_is31fl3731.charlie_wing import CharlieWing
import board
import busio
with busio.I2C(board.SCL, board.SDA) as i2c:
display = CharlieWing(i2c)
display.fill(127)
# Turn off pixel 4,4, change its brightness and turn it back on
display.pixel(4, 4, 0) # Turn off.
display.pixel(4, 4, 50) # Low brightness (50)
display.pixel(4, 4, 192) # Higher brightness (192)
