David,

It is my understanding that what this project would produce would be device
independent.

In Unix operating systems devices are files. For the I2C bus the device id
would /dev/i2c-0.(I do not believe this would be different on a PI vs and
Arduino). My goal is to produce Apache licensed libraries like this here:

https://blogs.oracle.com/acaicedo/resource/RPi-HOL/GPIOTest.java

Namely:

    final GpioController gpio = GpioFactory.getInstance();
    final GpioPinDigitalOutput led1 =
gpio.provisionDigitalOutputPin(RaspiPin.GPIO_00);

        // continuously blink the led every 1/2 second for 15 seconds
    led1.blink(500, 15000);

However, if people are open to device driver implementations (I would
assume these would be BSD drivers) I think that is an interesting
direction and I know of some FreeBSD user groups that might be
interested in getting involved.

Thanks,

Edward
