I assume you mean the datasheet for the attiny85 on the OSCCAL values? I installed the cores through links to the site from other posts, I didn't realize that was your site. Installing it all was a breeze, I'm hoping programming the 85 will be as simple. I'm in my second semester of my electrical engineering degree, so there are a lot of things I have yet to see, but I am pretty far ahead of the game. I have a couple practical projects I'm working on and one I'm thinking about doing that will be just for show. Hopefully I'll get the first done soon and I'll post it up!
