Project description

Introduction

Documentation Status Discord Build Status Code Style: Black

CircuitPython library for Sparkfun Qwiic Single Relay. This library is ported from examples at SparkFun Qwiic Relay

SparkFun Qwiic Single Relay (COM-15093)

SparkFun Qwiic Single Relay (COM-15093)

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 or individual libraries can be installed using circup.

Raspberry Pi Setup

Adafruit has an excellent tutorial on Installing CircuitPython Libraries on Raspberry Pi.

Quick Start Summary:

  • Start with the latest version of Raspbian with Wifi configured.
  • Enable SSH, I2C and SPI.
sudo raspi-config
  • Update your system to the latest version.
sudo apt-get update
sudo apt-get upgrade
  • Update the python tools
sudo pip3 install --upgrade setuptools

(If pip3 is not installed, install it and rerun the command)

sudo apt-get install python3-pip
  • Install the CircuitPython libraries
pip3 install RPI.GPIO
pip3 install adafruit-blinka

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 sparkfun-circuitpython-qwiicrelay

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

sudo pip3 install sparkfun-circuitpython-qwiicrelay

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 sparkfun-circuitpython-qwiicrelay

Installing to a Connected CircuitPython Device with Circup

Make sure that you have circup installed in your Python environment. Install it with the following command if necessary:

pip3 install circup

With circup installed and your CircuitPython device connected use the following command to install:

circup install qwiicrelay

Or the following command to update an existing version:

circup update

Usage Example

# import the CircuitPython board and busio libraries
import board

# Create bus object using the board's I2C port
i2c = board.I2C()

relay = QwiicRelay(i2c)  # default address is 0x18

# For a different address use QwiicRelay(i2c, address)
# relay = QwiicRelay(i2c, 0x19)

Upgrading

On supported GNU/Linux systems like the Raspberry Pi, you can upgrade the driver to the latest published version.

To upgrade for current user:

pip3 install --upgrade sparkfun-circuitpython-qwiicjoystick

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

sudo pip3 install --upgrade sparkfun-circuitpython-qwiicjoystick

Building locally

Zip release files

To build this library locally you’ll need to install the circuitpython-build-tools package.

python3 -m venv .env
source .env/bin/activate
pip install circuitpython-build-tools

Once installed, make sure you are in the virtual environment:

source .env/bin/activate

Then run the build:

circuitpython-build-bundles --filename_prefix sparkfun-circuitpython-qwiicrelay --library_location .
