Linux drivers for Atmel maXTouch touchscreen controllers

Introduction

This documentation gives information about integrating, building, configuring, and debuging drivers for Atmel maXTouch devices under Linux and Android. It assumes that the reader has either prior general understanding of Linux platform (e.g. installation, compilation) or is capable of finding the relevant information from the web.

Object-based Protocol

The control interface to all maXTouch chips conforms to a standard system known as the "Object-Based Protocol" which defines how to interact with the various objects that are implemented on any particular chip. It defines a mapping between registers and configuration values, and a way for objects to send status update messages to the host. A full description of the protocol is included in the protocol guide documentation issued by Atmel for each chip version.
