“This release is a milestone for open hardware. It is the sum of work and contributions from many, and the synthesis of ideas gathered and experimented in the last seven years. At the same time, it is also a start, as once again Wiring has opened up prototyping with electronics to wider audiences by defining an extensible architecture for future hardware, software and courseware; where novice, intermediate and experts will materialize their ideas, design and support for their new open hardware devices as well as develop applications unlocking new ways of thinking, and making, in an even simpler way.” — Hernando Barragán
What’s New in Wiring 1.0?
Wiring 1.0 supports almost 80% of the Atmel megaAVR microcontrollers with it’s Atmel 8 Bit AVR Framework core. As soon as Wiring 1.1 is released, new Framework cores for other microcontroller series and vendors will be added, including AVR XMEGA, Atmel tinyAVR, Texas Instruments MSP430, Microchip PIC32 series, and STMicroelectronics ARM Cortex M3.
When Hernando created Wiring in 2003, his goal was to create a platform which was easy to use, both in hardware and software, but it was only for a limited amount of hardware. In Wiring 1.0, we have expanded the vision to make the Wiring Framework easily portable to a lot more hardware. This vision allows the Wiring Framework to unite the programming of different brands of microcontrollers, enabling an easy way for artists, hardcore hobbyists, and even engineers to share code and ideas despite using different hardware.
For example, you can use the same sketch you use with your Wiring S board on a LeafLabs Maple. The Wiring S board uses an Atmel megaAVR controller, whereas the LeafLabs Maple uses an STMicroelectronics ARM Cortex M3 controller. 
Example of Different Target Hardware from Same Sketch
The merits of this may speak for itself, but we see the idea of people being able to share ideas and concepts no matter what type of hardware they use as a unique and expressive concept.
If you have a microcontroller series that you’d like to see use the Wiring Framework, please contact firstname.lastname@example.org.
As well as new Framework cores, Wiring 1.0 also has a super easy way to define your board hardware. So, for example, if you have created an Arduino compatible board, but uses different pin definitions, crystal frequency, or even a different controller, it doesn’t take a lot of effort to add your board to the IDE.
In fact, we have created several board definitions for Sparkfun, and their plethora of boards which are Arduino compatible. All you have to do is download the definitions and unzip the file into your sketchbook folder. For more information, seehttp://wiki.wiring.co/wiki/SparkfunHardware.
Along with the release, Wiring has a new affordable prototyping board to use with the Wiring Framework, called the Wiring S. It uses the Atmel ATmega644PA microcontroller, with 64 kilobytes of flash (code) memory, and 4 kilobytes of RAM. The New Wiring S Hardware

However, you are not limited to using only Wiring hardware. One of Wiring’s goals is to provide a homogeneous framework for all microcontrollers so that ideas and inventions can be shared. You can use a variety of different hardware that is already available (such as the popular Arduino hardware, various Sparkfun hardware, or even plain-jane Atmel DIP parts, like ATmega168, ATmega328P, or ATmega644PA). But, by buying the Wiring hardware, you help support the development of Wiring.
The libraries have been separated into categories. Core libraries are coded for specific hardware (microcontrollers). Cross-platform libraries are libraries which do not depend on hardware. And, of course, contributed libraries which come from all over the internet.
The fantastic reference has been expanded immensely. If you need something done, chances are, you will find a solution in the reference.
To make installation easier, there are installers for Mac OS X and Windows (XP and 7). A Linux package installer will be available in the near future.
The Wiring project was initiated in 2003 by the Colombian artist and designer Hernando Barragán while he was studying at the Interaction Design Institute Ivrea in Italy, and the project is currently developed at the School of Architecture and Design at the Universidad de Los Andes in Bogotá, Colombia. The Wiring IDE builds upon the Processing IDE, of the open source Processing project initiated by Casey Reas and Ben Fry, both formerly of the Aesthetics and Computation Group at the MIT Media Lab.
Using the Wiring IDE and Framework, people design and create projects which interact physically with the environment. Furthermore, people use it to prototype electronic projects and even use the Framework in products.
In 2005, Wiring spawned another project, Arduino, which uses the Processing IDE together with a simplified version of the Wiring Framework. Since then, the Arduino community has grown to hundreds of thousands of people, all enjoying the simplicity of the Framework on the Arduino hardware.
Who is Wiring?
The core Wiring team is composed of Hernando Barragán, Brett Hagman and Alexander Brevig, while a small team of volunteers have been making additional contributions to Wiring. For a full list of contributors visit http://wiring.org.co/about.html. The current state of the project wouldn’t have been possible without this assistance.
 The Wiring Framework core for the LeafLabs Maple, will be available in Wiring 1.1, by the end of 2011, with more cores being added all the time! Please check http://wiring.org.co/ for more information.
