Auf Hack a Day habe ich einen interessanten Artikel über Projekt gefunden, welches einen AVR Controller (ATmega644) verwendet, um ein Display mit Touch-Bedienung (und einfacher 3D-Engine!) anzusprechen: 8-bit Devise quenches iPhone envy.
Die Ankündigung des Programmierers findet sich hier: AVR homebrew device with iPhone aspirations, hier ein kleiner Auszug:
Microtouch: AVR homebrew device with iPhone aspirations. Can you make an iPhone out of an AVR? No.
Can you get a surprising amount of functionality out of a humble 8 bit processor and a cheap touch LCD? Yes.Hardware
320×240 LCD with 4 wire resistive touch screen – a ELT240320ATP variant from a dead Sylvania MP3 player – uses a ILI9325 controller.
12Mhz Atmega644 CPU with 64k Flash and 4k RAM – demo fits in 32k.
USB connector for PC communication and charging.
Lithium polymer battery with software controlled power.
Software controlled backlight.
SD Micro slot.Software
LCD driver to support blitting image decompression and smooth scrolling.
Z-sorted span 3D engine with zero overdraw.
Basic UI framework for gadgets and poorly drawn pictures.
USB mouse or keyboard HID support.
Sampling profiler.
Movie playback.
Sprite engine.
Es gibt auch eine eigene Projekthomepage auf SourceForge: microtouch, wo sowohl die dazu verwendete Schaltung als auch der entsprechende Code veröffentlicht wurde. Jedenfalls ein sehr interessantes Projekt.

It is often wonderful to see wherever technology goes and the long term of gaming is no different. There are quite a few cool and really innovative technologies arising. There is no way to inform which one particular will make the next large wave, but 1 issue is for confident, it will have one thing to do with getting rid of the remote as we know it!
