Python library for AW9523 GPIO expander and LED driver
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-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
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
