Python library for AW9523 GPIO expander and LED driver
Project description
Introduction
Python library for AW9523 GPIO expander and LED driver
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-aw9523To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-aw9523To 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-aw9523Usage 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.valueContributing
