PARTS

• Atmel AVR AT90USB demo kit (Mouser #556-A90USBKEY; $31.92)

STEPS

1. Plug ‘n Point. Boot your Eee PC to its default Xandros OS. Use the provided USB cable to plug the AVR USB key into an available USB port. Use the on-board joystick to navigate around your desktop. Pressing the HWB key on the AVR USB key is equivalent to a left-button mouse click.

2. You’re Dismissed. The Eee PC OS will periodically display a "Removable Media" window while you are using the AVR USB key. Dismiss this window, or use it to access the built-in 16MB of data flash storage.

3. My Other PC Is An XP. If you’ve installed Windows XP on your Eee PC, then you can install the AVR USB key HID demo software under that OS. This software will enable you to gain access to the device’s LEDs and temperature sensor.

Once you’ve outgrown all of this kid stuff, break out the AVR programmer, solder on some thin row .05 pitch headers, and write your own program for the AVR USB key. Then you will go to the HID of the class.
