Joy-it EnOcean Pi How to use with Raspberry Pi
How to use EnOcean Pi with
Raspberry Pi
Overview: Source: EnOcean Pi
EnOcean Pi transforms Raspberry Pi into a gateway, allowing wireless communication with
thermostats and
switches around your home, thus automating temperature and lighting systems. It provides a bidirectional
radio interface and a bi-directional serial interface.
This document provide you a step-by-step guide on how to use EnOcean Pi with Raspberry Pi:
Step-By-Step Guide:
If you have an Raspberry Pi and an EnOcean Pi you can use EnOcean Link with Raspberry Pi to
compile the
code for Raspberry Pi. EnOcean Link is a powerful library for EnOcean Pi to handle packets,
telegrams and
messages received in an ESP3 Format.
First connect the Raspberry Pi and EnOcean Pi with extension board on Raspberry Pi as shown
below:
To run the EnOcean Link on Raspberry Pi, you need to download the EnOcean Link source code from
here:
(Download). After downloading the EnOcean Link you can compile it directly on Raspberry Pi or
compile it on
an PC an deploy it on Raspberry Pi (please refer: How to Compile for Raspberry Pi). Then simply
copy the
resource or use remote deployment, for the start you can either play with Hello World or one of the
tutorials.
For your convenience, here's the summary of the steps:
• Set up your Raspberry Pi (as shown above) and download EnOcean Link (Download).
• Now you need to specify the right serial port of your gateway connected to your Raspberry Pi, please
adjust the defines as below:
sudo chmod 777 /dev/ttyAMA0
Then you use this define:
#define SER_PORT "/dev/ttyAMA0"
• Cross compile EnOcean Link for Raspberry Pi (please refer: How to Compile for Raspberry Pi).
• Deploy the binaries (please refer: How to Compile for Raspberry Pi or copy.
• When needed set the access rights of your gateway connected to your Rasp berry Pi:
sudo chmod 777 /dev/ttyAMA0
• Run it. Please remember to follow the licensing of EnOcean Link - Trial License Agreement . Enjoy.
Makefile:
This section will helps you to compile EOLink from the makefile. There are three possibilities:
• ReleaseLib - EOLink library with release compiler settings
• DebugLib - EOLink library with debug compiler settings
• DebugSandbox - Example EOLink application
After starting the command prompt, navigate to the directory of the main makefile called makefile. For
example
to compile ReleaseLib, you should do this:
#:~/workspace$ cd EOLink/ReleaseLib/
#:~/workspace/EOLink/ReleaseLib$ make all
This compiles EOLink and generates library libEOLink.a in the directory. The DebugSendbox
generates
EOLink executable.
