FOR IMMEDIATE RELEASE
Objective Development Announces Commercial Licenses and Bundled USB IDs
for Their Free Firmware-Only USB Driver for Atmel's AVR
Vienna, Austria - January 31, 2006 -- Objective Development today
released a new version of their firmware-only USB driver for Atmel's
microcontrollers (AVR-USB), just in time for the driver's one year
anniversary. This version adds new licensing options and free USB
Product IDs bundled with all license types, even with the free Open
Source compliant license.
AVR-USB is targeted to small companies and hobbyists designing hardware
with USB connectivity based on standard AVR microcontrollers. It
implements a low speed USB device in the same way as a Software-UART
implements asynchronous serial data transfer. The only hardware
resources needed from the AVR microcontroller are two I/O pins, one of
them must be an edge triggered interrupt.
Since RS232 ports have become rare in modern computers, USB is the
method of choice for connecting various gadgets to the PC. The major
drawback for small companies and hobbyists is the relatively large
upfront investment which is usually required to work with USB: You need
to buy a USB Vendor ID from usb.org (currently 1,500 USD) and maybe a
new development system for USB capable microcontrollers. Furthermore,
microcontrollers with USB are often available in SMD packages and large
quantities only, making things even harder for small startup companies
AVR-USB addresses all these issues. It comes with an Open Source
license, a USB Product ID which can be used for free (shared according
to the certain implementation rules), it is based on the free GNU
compiler as development environment and works with low cost AVR
microcontrollers which are available in DIP packages. The PC side
can be constructed with libusb, a free USB abstraction library which is
available for Windows, Linux, Mac OS X and BSD Unix. No Microsoft SDK
development environment is required for Windows driver development.
Two affordable commercial license types are available for those who can
not agree to the publication requirement of the Open Source license.
entry level license for 199 EUR allows using AVR-USB in up to 150 units
and comes with a dedicated USB Product ID for exclusive use. The
professional license for 500 EUR has virtually no limit in the number
units (fair use) and comes with two dedicated USB Product IDs.
AVR-USB can be downloaded as part of an example application at the URL
