This interface implements the callback event handler for GPIO interrupt state changes.
The Gertboard has an on-board Digital to Analog (DAC) converter and an Analog to Digital (ADC) converters.
<[>WiringPi GPIO Control[>
This class provides static methods to configure the native Pi4J library to listen to GPIO interrupts and invoke callbacks into this class.
This class provides the event object for GPIO interrupt state changes.
This utility class is provided to export, unexport, and manipulate pin direction.
WiringPi includes a library which can make it easier to use the Raspberry Pi’s on-board I2C interface.
Part of wiringPi is a library to allow access to parallel interface LCD displays (Those that use the popular Hitachi HD44780U or compatible controllers)
Before using the Pi4J library, you need to ensure that the Java VM in configured with access to the following system libraries: pi4j wiringPi This library depends on the wiringPi native system library. (developed by Gordon Henderson @ http://wiringpi.com/)
WiringPi includes a simplified serial port handling library.
WiringPi Shift Library
WiringPi includes a software-driven PWM handler capable of outputting a PWM signal on any of the Raspberry Pi's GPIO pins.
WiringPi includes a software-driven sound handler capable of outputting a simple tone/square wave signal on any of the Raspberry Pi’s GPIO pins.
WiringPi includes a library which can make it easier to use the Raspberry Pi’s on-board SPI interface.
