Adafruit's Legacy Raspberry Pi Python Code Library

What happened to all the Raspberry Pi Python code!?

In the past this repository held all of the Raspberry Pi related Python code that Adafruit published. For example code to talk to sensors like the BMP085, TCS34725, and other hardware like character LCD plates. Over time we found it difficult to manage so much code in a single repository, and couldn't easily put the code on Python's package index for simple installation. Now we've broken out all of the previous Python code into individual GitHub repositories, and we've loaded all of these repositories on the Python package index so they can be installed with pip (note that pip won't install example code so for most users it's recommended to install from source).

In addition all of the Python libraries below support both Python 2.7 and Python 3.x! Note if you do plan to use Python 3 it has totally separate libraries from Python 2 so you might need to install all the libraries you use in both Python 2 and 3. See this video stream for more details: https://www.youtube.com/watch?v=rRFG32EebNc In particular on a Raspberry Pi you probably want to install Python 3, PIP for Python 3, and the RPi.GPIO library (used to talk to GPIO pins on the Pi) with these commands:

sudo apt-get update
sudo apt-get install -y python3 python3-pip python-dev
sudo pip3 install rpi.gpio

Where do I find the new Raspberry Pi Python code?

Here is a table with each of the old libraries and a link to their new unique GitHub repositories and easy pip install names:

Old Library Name New Library Location New pip install Package Name Notes

Adafruit_I2C https://github.com/adafruit/Adafruit_Python_GPIO adafruit-gpio See updated I2C code in the Python GPIO library. Import with import Adafruit_GPIO.I2C as I2C and create an instance of I2C.Device instead of the old Adafruit_I2C class.

But I need the old code! What can I do?

Don't worry the old Adafruit Raspberry-Pi Python code can be found in the legacy branch of this repository. This is a snapshot of the old code before it was refactored into individual libraries. Note this legacy code will not be maintained!
