Smiley's Workshop 4
Important Mental Health Advisory
The Workshop uses the latest WinAVR. The book does not. So the examples in the workshop will compile with the latest WinAVR, while the book requires the older version you can get in my downloads section. If you want to use the book examples with the new WinAVR YOU MUST ADD #include \ at the top of each C module. I expect this to drive a few people crazy and for that I apologize.
AND if you want to really make yourself crazy then do not use the default directories when setting up WinAVR and AVRStudio. The only way AVRStudio can find the WinAVR stuff is if both install using the default paths. If you decide that you want them to install elsewhere, then be prepared to know how to reset the paths involved and if you ask me how to do that, I'll refer you to this paragraph.
AND AND For my mental health, please direct all technical questions to the forum on www.avrfreaks.net. I check it as often as I check my emails and there are plenty of folks there who can probably answer your question before I get to it. Also, if you do email me and it is not Smiley Micros specific, I may ask you to post on AVRFreaks anyway since other folks will have the same question and so I can point them to the answer already given..
