ATMEL AVR

The NanoVM - Java for the AVR

The NanoVM is a java virtual machine for the Atmel AVR ATmega8 CPU. With the NanoVM, the AVR can be programmed in the popular Java language using the standard Sun JDK.

FAT16 / FAT32 driver for Atmel AVR

This file system driver reads and writes to FAT file systems. It is designed to work with the ATmega128 microcontroller. It is ideal for use with MP3 players and data loggers.

DTMF Decoder

Decoding DTMF (Dual Tone Multi frequency) with MT8870 chip and AVR x2313 microcontroller.

I2C EEPROM programmer

This EEPROM programmer reads, writes and erases I²C 24C EEPROM devices through a PC serial port (RS-232) interface.

ATTiny Board

With this small board you can program most of the AVR ATTiny microcontrollers or you can build your projects to use it in a stand alone application. It can be powered with a 9V battery because it has 5V voltage regulator on it.

AVR-MIDI - an USB MIDI-class compliant device

This is an inexpensive DIY MIDI controller device for USB. It consists of a simple AVR ATMega16 with driver software from Objective Development (see).

Direct connecting: AVR to USB, no HW converters

Some techniques to connect AVR-based device to USB without a specialized HW, just only in the SW way.

LiberLab

The Open Source project Liberlab aims to help democratize educational scientific experimentation through the creation and use of a DIY digital lab at a very low price. Liberlab can also be used to learn about robotics, automation, human-machine interface or interactive arts.

Arduino + SD card

SD card read/write with Arduino.

UsbProg-SHARP

A Multi-purpose USB Device with ATMega32
