adafruit-circuitpython-aw9523 1.0.3

Introduction

Python library for AW9523 GPIO expander and LED driver

Dependencies

This driver depends on:

• Adafruit CircuitPython

• Bus Device

• Register

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-aw9523

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-aw9523

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-aw9523

Usage Example

import board
import digitalio
import adafruit_aw9523

i2c = board.I2C()
aw = adafruit_aw9523.AW9523(i2c)

led_pin = aw.get_pin(0)  # LED on AW9523 io 0
button_pin = aw.get_pin(1)  # Button on AW io 1

# LED is an output, initialize to high
led_pin.switch_to_output(value=True)
# Button is an input, note internal pull-ups are not supported!
button_pin.direction = digitalio.Direction.INPUT

while True:
    # LED mirrors button pin
    led_pin.value = button_pin.value
