Hi,

The library source code and a demo program is available here:

https://github.com/erikarn/freebsd-liblcd

It includes the wiring needed to hook the example OLED board up
(http://www.adafruit.com/products/684) to a Carambola 2 evaluation
board.

Anything you can get 5v and 5 GPIO pins from will work. (Well, as long
as there's also libgpio / gpio API support for your device..)
