PI4J VERSION 1.0 RELEASE

The much anticipated Version 1.0 of the Pi4J Library is finally released!

http://www.savagehomeautomation.com/projects/pi4j-version-10-released.html

The road to release 1.0 has been a long one, but 1.0 offers many new features, bug fixes and improved stability over the earlier releases.  We feel that the project has been in incubation long enough and is ready for an official 1.0 launch.
Pi4J Version 1.0 is also available in Maven Central.  <<View in Maven Central>>

• Released under GNU LGPLv3 license.
• Added support for RaspberryPi v2 Model B
• Added support for RaspberryPi Model A+
• Added support for RaspberryPi Model B+
• Added support for RaspberryPi Compute Module
• Added support for debounce logic on digital input pin events
• Added support for Button component interface
• Added support for Pibrella device
• Added support for SPI modes
• Added support for building pi4j-native project directly on the Pi (using maven)

• Added APT package and repository support (repository.pi4j.com)
• Simplified native library loader to find embedded hard-float native lib
• Fixed JDK8 build errors.
• Removed support (and complicated builds) for soft-float ABI
• Updated documentation in preparation for 1.0 release

Hi Robert,

I have a problem with lib Pi4J and Raspberry Pi 2.

No compilation error, but I can not  turn on the LED.

I am just starting out with Java.

The LED is connected to pin 12 

If I send a command from the shell to the GPIO, 12 the LED lights up, but if I use the library PI4 (GPIO_01)j, the LED does not work ..

Can you help me to understand ?

In the porject i use the lib 1.0

i download the jar file (## RELEASES 2015-04-18 :: 1.0) and i add on NetBeans project

Thanks

Michele
