The Atmel AVR ONE! unit requires that a front-end debugging environment (AVR32 Studio or AVR Studio 4.15 or later, or Atmel Studio) and associated utilities are installed on your computer. For system requirements of these packages, consult www.atmel.com.
The AVR ONE! unit must be connected to the host computer using the USB cable provided. To achieve streaming trace readout from the AVR ONE!, the USB port on the computer must be USB 2.0 high-speed compliant. If the computer only supports USB 1.1 (or "full-speed" USB), the AVR ONE! can still be used for debugging (Note: restrictions apply, see Known issues), but trace will be limited to operating in buffer mode.
The AVR ONE! unit must be connected to a 12V external power source, which is included with the kit.
