woolseyworkshop-circuitpython-74hc165 1.0.0

CircuitPython driver for 74HC165 shift register.

Introduction

CircuitPython driver for 74HC165 shift register.

Dependencies

This driver depends on:

• Adafruit CircuitPython

• Bus Device

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 woolseyworkshop-circuitpython-74hc165

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

sudo pip3 install woolseyworkshop-circuitpython-74hc165

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install woolseyworkshop-circuitpython-74hc165

Usage Example

import time
import board
import digitalio
import wws_74hc165

latch_pin = digitalio.DigitalInOut(board.D5)
sr = wws_74hc165.ShiftRegister74HC165(board.SPI(), latch_pin)

pin1 = sr.get_pin(1)

while True:
    print(f"pin 1 = {pin1.value}")
    time.sleep(1)
