News AVR Projects

Yet another project demonstrating unbeatable power of AVR microcontroller in 8-bit microcontroller family. The AVR Homebrew device cant really beat the power of ARM but still cool enough to do the big tricks possible.



Hardware Features:
320x240 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 Features:
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.

The complete source code, schematics and PCB layout are available open source at https://sourceforge.net/projects/microtouch/
