I'm sorry if any such previous post is done, but I dint find anything similar thru search.
I'm using AVR studio (v 4.13.528) and WinAVR. Everytime when I start a new project, I've to set the optimization level, include directories, etc. thru the GCC plugin. If such things can be stored as a known configuration, then it will be fast to start with. Is there already a way to do this?
