I recently ordered a couple of JeeNode v6 boards. These boards are mostly Arduino-compatible (standard shields won’t fit) and optionally contain an RF12 radio module. They are ideal for creating wireless sensors.
- Download and install the Arduino IDE
- Set your serial port and speed correctly (57600 baud)
- Download and install the Ports library and RF12 library (see below)
On Mac OS X, the Arduino IDE stores your sketches in your home directory, under ~/Documents/Arduino. Open a Terminal window and type the following commands:
svn co svn://svn.jeelabs.org/jeelabs/trunk/libraries/Ports
svn co svn://svn.jeelabs.org/jeelabs/trunk/libraries/RF12
Done! The RF12 library is now installed. Do not forget the Ports library, or you will see errors like this:
RF12demo.cpp:7:19: error: Ports.h: No such file or directory
Restart the Arduino IDE. You should now see several new entries under File | Sketchbook | libraries | RF12. Open the RF12demo sketch and try to compile it. There should be no errors.
For a more meaningful demonstration you will of course need at least 2 JeeNodes with RF12. Load File | Sketchbook | libraries | RF12 | pingPong and try to compile it. Upload to both JeeNodes and watch the Serial Monitor. If there is traffic you will be greeted by “OK Hello!”:
