python library for the AS7343 spectral sensor

Project description

AS7343 Spectral Sensor

Build Status Coverage Status PyPi Package Python Versions

AS7343 is a 14-channel multi-purpose spectral sensor. It can detect 14 spectral channels - 12 in the visible spectrum (VIS) to near-infrared (NIR) range, a clear channel and flicker channel.

You can buy our AS7343 breakout here!

Installing

We'd recommend using this library with Raspberry Pi OS Bookworm or later. It requires Python ≥3.7.

Full install (recommended):

We've created an easy installation script that will install all pre-requisites and get your AS7343 breakout up and running with minimal efforts. To run it, fire up Terminal which you'll find in Menu -> Accessories -> Terminal on your Raspberry Pi desktop, as illustrated below:

Finding the terminal

In the new terminal window type the command exactly as it appears below (check for typos) and follow the on-screen instructions:

git clone https://github.com/pimoroni/as7343-python
cd as7343-python
./install.sh

Note Libraries will be installed in the "pimoroni" virtual environment, you will need to activate it to run examples:

source ~/.virtualenvs/pimoroni/bin/activate

Development:

If you want to contribute, or like living on the edge of your seat by having the latest code, you can install the development version like so:

git clone https://github.com/pimoroni/as7343-python
cd as7343-python
./install.sh --unstable

Install stable library from PyPi and configure manually

  • Set up a virtual environment: python3 -m venv --system-site-packages $HOME/.virtualenvs/pimoroni
  • Switch to the virtual environment: source ~/.virtualenvs/pimoroni/bin/activate
  • Install the library: pip install pimoroni-as7343

In some cases you may need to us sudo or install pip with: sudo apt install python3-pip.

This will not make any configuration changes, so you may also need to enable:

  • i2c: sudo raspi-config nonint do_i2c 0

You can optionally run sudo raspi-config or the graphical Raspberry Pi Configuration UI to enable interfaces.
