CircuitPython library for IS31FL3731 charlieplex LED matrices.
Project description
Introduction
CircuitPython driver for the IS31FL3731 charlieplex IC.
This driver supports the following hardware:
- Adafruit 16x9 Charlieplexed PWM LED Matrix Driver - IS31FL3731
- Adafruit 15x7 CharliePlex LED Matrix Display FeatherWings
- Adafruit 16x8 CharliePlex LED Matrix Bonnets
- Pimoroni 17x7 Scroll pHAT HD
- Pimoroni 28x3 (r,g,b) Led Shim
- Pimoroni Keybow 2040 with 4x4 matrix of RGB LEDs
- Pimoroni 5x5 RGB Matrix Breakout
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-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 .env source .env/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)
