Framebuffer

Developed upon udlfb. udlfb is DisplayLinks's kernel framebuffer + USB driver. Most of the framebuffer work in this driver is taken directly from udlfb.

Usb communication

USB communication is done using Android Open Accessory (AOA) protocal with the Android device setup into Accessory Development Kit (ADK). Read about ADK on Android developers webpage.

A bare-bone implementation of the ADK driver, with only usb communication, can be found here
