AVR-USB Interfaces and Adapters

This page lists projects implemented with AVR-USB. Please remember: We also want to list your project! If you don't have a web site to publish it, we can host it in our Wiki.

uDMX - a DMX Interface

uDMX is a USB bus powered DMX interface. DMX (Digital MultipleX) is a bus for controlling stage lighting and special effects devices. This particular implementation comes with a Unix command line tool and plugin module for the Max/MSP software.

AVR-CDC - a USB to Serial Converter

This ingenious project implements the USB Communication Device Class, making use of the operating system's driver for the device class. No separate driver is needed on the host! Although it goes somewhat beyond the USB specification, it works on all major operating systems.

SNES/NES Gamepad and Atari Joystick to USB Adapter

NES and SNES are gaming consoles. When playing NES and SNES games with an emulator, nothing is better than using the original gamepads. This project converts the NES/SNES interface to USB, emulating a USB joystick. A project update from December 2006 brought support for Atari joysticks. See the project's News section for a link. An illustrated guide for building a controller for 4 SNES/NES gamepads can be found here and here.

PPM RC to USB Interface

This project is a USB joystick controlled by a PPM radio remote control transmitter. There are a lot of such projects around based on different MCUs and USB drivers. But this one is Open Source. It provides very accurate PPM handling and a number of filtering options. Home constructors will like the optional servo tester mode and ADC interface instead of PPM for self-made control boxes.

C64 Keyboard

This project implements a full-blown USB keyboard based on the keyboard matrix of a Commodore 64. The fun in this is that you can put a state of the art miniature PC into a C64 breadbox. Technically, it demonstrates how a real USB keyboard can be implemented with AVR-USB.

i2c-tiny-usb

This project is a tiny low-cost I2C bus adapter. It is meant to replace bit-banging adapters for the parallel port. Advantages are built-in power supply, less CPU load and a very low number of components. The image shows an example application with a DS1621 temperature sensor.

USB-Servo

This device controls a servo over USB. Potential applications are only limited by your imagination. The image shows a mouse pointer finder, similar to the classic x-eyes application on X-Windows.

3DP-Vert

For many people, Microsoft's Sidewinder 3D Pro is the only joystick they ever want to use. Unfortunately, most modern computers don't have a Game Port which is required to connect this joystick. 3DP-Vert allows you to connect the Sidewinder 3D Pro via USB.

USB-Servo 2

A second USB servo controller. This one extends Ronald Schaten's USB-Servo to 6 servos with a separate supply. It was designed to control the servos of a robot.

USBJoy

This project is primarily for Russian speaking users. It's similar to the SNES/NES gamepad to USB adapter above, but connects to the following consoles: Dendy (Russian NES), SEGA Mega Drive-II, PlayStation and PlayStation-2. You can use these gamepads with game console emulators and computer games.

xu1541

C64 floppies can only be read by Commodore floppy drives. Unfortunately, these drives cannot be directly connected to modern PCs. This project is an adapter which connects the VC 1541 floppy drive via USB.

N64/Gamecube Adapter

This is another variation of the NES and SNES gaming console adapter. This one turns a Nintendo 64 or a Gamecube controller into a USB joystick.

USB2LPT - USB to Parallel Port Converter

This USB to Parallel Port converter is not only of practical use, it also demonstrates how the low power sleep mode demanded by the USB specification can be implemented with AVR-USB.

SNES Joypad

This is another implementation of Raphael Assenat's idea of an SNES to USB adaptor. This one is smaller in size (eight pin AVR) and uses less components. The description is available in German only.

AVR-MIDI - a Class Compliant MIDI Device

This MIDI controller uses the same tricks as AVR-CDC to implement a MIDI class compliant USB device. It does not require special host side drivers, but since it goes beyond the specification for low speed devices, it may not work on some hosts.

Ginger

Ginger is a physical computing platform similar to Gainer (which is based on a PSoC chip). You can read digital and analog inputs and set output data, all over USB. Ginger's web site is currently in Japanese only, but Readme file in the project is in English.

Pepper-MIDI - Control SX-150 Synth via MIDI

Who said that analog synths have no MIDI interface? This project adds MIDI to the Gakken SX-150 synthesizer.

FunkUSB - DCF77 Receiver with USB

This project is a radio clock receiver (DCF77) which connects to the host computer via USB. Documentation is in German only since the DCF77 signal can't be received far away from Germany anyway.

PS2USB - Sony PlayStation Adapter

No, this is not a converter for PS2 keyboards or mice. This project converts Sony PlayStation 1 or 2 controllers into a USB joystick.
