Bunch of knobs connected to computer via USB. Useful for controlling software scope (e.g. PicoScope). See http://www.colinoflynn.com/tiki-view_blog_post.php?postId=48 for details.
Built for the AT90USBKEY board using the USB1287 device, also works for the Teensy++ 2.0 using the USB1286 device. You've got to change both the MCU & F_CPU as follows:
| Board | MCU= | F_CPU= |
|---|---|---|
| AT90USBKEY | at90usb1287 | 8000000 |
| Teensy++ 2.0 | at90usb1286 | 16000000 |
