A fair word of warning: This project has only ever been used on OS X. Linux shouldn't be a problem, but you've probably got to fiddle around quite a lot on Windows. However, if you do, let me know and I'll be happy to include your findings and improvements!

Installation

On the Pi

1. Zeroconf aka Bonjour

   Usefull, but not necessary: sudo apt-get install avahi-daemon (.local)

   You might also want to change the hostname of your Pi: sudo nano /etc/hostname

2. Configure I2C

   Source: https://learn.adafruit.com/adafruits-raspberry-pi-lesson-4-gpio-setup/configuring-i2c

   • add "i2c-bcm2708" and "i2c-dev" to /etc/modules
   • sudo apt-get install "python-smbus" and "i2c-tools"
   • comment out "spi-bcm2708" and "i2c-bcm2708" in /etc/modprobe.d/raspi-blacklist.conf (if it exists)
   • check success: sudo i2cdetect -y 1 should detect something (not an empty table, probably 40 & 70)

3. Install Python 3.4

   See http://procrastinative.ninja/2014/07/20/install-python34-on-raspberry-pi/

4. Compile python-smbus for Python3

   See http://procrastinative.ninja/2014/07/21/smbus-for-python34-on-raspberry/

5. Install dependencies

   Bundler: sudo gem install bundler Gems: (sudo) bundle install

   Python: rake dependencies:install

On your Workstation

1. Install dependencies

   Bundler: sudo gem install bundler Gems: (sudo) bundle install

2. Install Python3-Protobuf

   If you want to change the protocol definition, you need a protobuf compiler, generating valid Python 3 code

   DL Python3-Protobuf 2.5.1 (https://github.com/GreatFruitOmsk/protobuf-py3) install: brew install autoconf automake libtool, ./autogen.sh , ./configure, make, (sudo) make install

Usage

There's a Rakefile that makes executing common tasks more convenient. Run rake -T or rake -D for a list of tasks and descriptions.

To start a server locally execute rake server. To connect to that server with an interactive command line client run rake client[localhost].
