I have been looking at the document, which can be downloaded from here:
On page 6, step 1 says to open project BasicLED_Control.aps
I can't find where it should be downloaded from. The prerequisites for this app note are AVR Studio 4.18 and WINavr 20100110, but the projects don't seem to be included as part of the software.
Can someone tell me where these projects can be found?
