How to implement Arduino programming in AVR Studio?

Question

Arduino

There is an arduino board (uno and mega), there is a working program.
How to reflash this whole thing and transfer from the standard Arduino IDE to AVR Studio? So that the program can be written in normal languages?

Answer 1

If you want to use the bootloader from Arduino, then there is this article: habrahabr.ru/post/140276
If the bootloader is not needed either, then you need to buy a programmer and flash through it.

Answer 2

almost nothing.
The problem is in the Arduino framework. You need to duplicate it in Studio on C.
There are probably some early ports, but I doubt it.
Although there are not so many changes in terms of scope of work. And all functions are simple.
