JPigpio is an all java interface to the pigpio socket interface of the pigpio library. JPigpio is a work in progress. Currently just a few of the pigpio commands are available. This includes the general commands to set/get the mode of a GPIO pin, read/write to/from a GPIO pin, set/get servo pulsewidth, the commands to set up notifications on level changes, get the ticks since boot and version information. More commands will be added regularly to this list.
