JeeLib is a collection of headers, classes, and sample sketches for use with the Arduino IDE. It was written and extended over the years to simplify experimenting and exploring the JeeNode and other products from JeeLabs. And what's JeeLabs? Oh, just some guy with a weblog, having fun with Physical Computing :)
The JeeLib code was merged from two separate libraries: "Ports.h" and "RF12.h". You can still include these headers files, but since you often will need to use code from both of them, the recommended way to use this library is to add this single directive at the top of your sketches:
JeeLib should work with Arduino IDE versions 1.0 and up.
These are the main classes:
The other major implementation in this library is the RF12 wireless driver for the "RFM12" and RFM12B" wireless modules from HopeRF.
Last but not least, there are about a hundred demo sketches in the "examples" folder, ready to try out all sorts of features and tricks, and to easily hook up to specific sensors and other interfaces.
There is a BMP085 class with the code to interface to the sensitive pressure + temperature sensor on the Pressure Plug. It's separate from the rest because the code is larger - to use it, include the "PortsBMP085.h" header.
The RF12 class defined in the "RF12sio.h" header is NOT the core RF12 driver, but a wrapper to try and send serialized data through via the RFM12B. While it does work somewhat, its use is discouraged. It's too weak for serious use.
In the AVR / ATmega / Arduino / JeeNode world, there are a couple of terms which are used to designate different things in different contexts. Such as:
