V-USB Interfaces and Adapters

[ HID | Interfaces | Data Acquisition | Displays | Programmers | Control | Other ]

This page lists projects implemented with V-USB. Please remember: We also want to list your project! If you don’t have a web site to publish it, you 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. There are also instructions for building the adapter without a PCB.

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 V-USB.

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.

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.
