raspberry_pi_i2c_scd4x_python

Python bindings for raspberry-pi-i2c-scd4x

The original driver, written in C/C++, is included as a submodule. This repository contains python bindings for it.

Note that in order to make this simpler to use in Python, some methods may take different parameters or return different types of values than in the original driver.

For documentation on functions, see scd4x_i2c.h from the submodule.

Tested on Raspberry Pi.

Setup:

Enable I2C (if using Rapsberry Pi)
sudo raspi-config
Then enable I2C from the menu

clone this repo, make sure to fetch the submodule as well
git clone --recurse-submodules https://github.com/vinicentus/raspberry_pi_i2c_scd4x_python.git

cd into directory
cd raspberry_pi_i2c_scd4x_python

set up python for developement
sudo apt install python3-dev

Recommended: create a python venv, and activate it
sudo apt install python3-venv
python3 -m venv venv
source venv/bin/activate

install the "cffi" libary using pip
python3 -m pip install cffi

run build.py (from inside the directory)
python3 build.py

Example usage:

See example.py

Note that this must be run as a module, from outside the package directory:
cd ..
python3 -m raspberry_pi_i2c_scd4x_python.example
