CircuitPython driver for the IS31FL3731 charlieplex IC

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

Dependencies

This driver depends on:

• Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Usage Example

Matrix:

import adafruit_is31fl3731
import board
import busio
with busio.I2C(board.SCL, board.SDA) as i2c:
    display = adafruit_is31fl3731.Matrix(i2c)
    display.fill(127)

Charlie Wing:

import adafruit_is31fl3731
import board
import busio
with busio.I2C(board.SCL, board.SDA) as i2c:
    display = adafruit_is31fl3731.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)
