Pi4j port for pcduino
The GPIO manager  doesn't really help because it can only read/write digital pins. Pi4j offers native integration to many more features, like native I2C, Serial, GPIO interrupts, etc.

I have started porting pi4j for the PCDuino board at https://github.com/fsamir/pi4j

Don't expect a complete port, as it is not a critical project for me. So far I was able to allow I2C on /dev/i2c-2. Next step will be OneWire support.
