Question

I am learned to program in arduino but i want to use all the space available.Is it possible to make a software that takes arduino code and switches it over to avr studio or is it not required at all? I don't want a book to learn programming in avr studio but is it possible to turn arduino wiring to avr studio format without rewriting the whole program to avr studio format?

the boot-loader does not do that i'm afraid, the boot-loader is a small program put into semi protected space on the arduino (328 and the like) to allow you to upload the sketches to the board without a JTAG or ISP programmer, it operates the serial port and responds to the load commands from the IDE/Compiler/AVR.

On power up the boot loader is the first piece of code to be executed, if there is no attempt to load a new sketch, then it will pass execution to the existing sketch in memory. It does not interpret or convert anything.

The GCC Compiler on the PC/MAC/Linux workstation creates the machine specific code (Behind the scenes on the Arduino IDE), it creates a HEX file ready to be uploaded to the MCU. An up-loader program then communicates with the boot loader (It resets the MCU and then quickly talks to the boot loader before it passes control to the existing sketch). if it gets an answer it transfers the binary code to the board.

you can use the "Upload Using Programmer" command rather than the simpler "Upload" option on the IDE to bypass the boot loader and use direct programming (Via the MISO, MOSI, etc pins) using the ISP socket on the Arduino boards (6 pin header as 2 rows of 3). In this case you can bypass the bootloader and potentially upload a bigger program

If you google Arduino, nobootloader, ISP header you should find plenty of information

I will answer your question, but I want to ask you why you need to do so? Arduino's processing language is build on Cplus plus with some keywords added and functions added to ease the understanding of what you are writing. Any programming language is a way of describing the functionality that you want to implement. It's the compiler's job to take what you told it and turn it into machine code which is basically a reduced set of instructions (hence the name RISC) and make things work. E.g. [code] unsigned char i=5; while(i>=0){ i--; } [/code] should get translated to something like [code] mov Rn, #05h ; where Rn is any register number or loop1: djnz Rn, loop1 [/code] Now the way I see it, code in Arduino and code in AVR studio will not make much of a difference in terms of the space used because of the IDE. Optimum space usage is possible if: 1. The compiler and it's optimizations. 2. The code writer understands how the compiler will convert and writes good quality code with an understanding of the architecture. E.g. the above example will be better than if you use float instead of the UCHAR and worst if you try using FOR LOOP that counts up instead of the decremented WHILE loop. -> So if you are worried about wasting space with extra code, I suggest you write programs in assembly(like I do some times) or understand the AVR architecture and the compiler's output to the code you write. -> The reason why most people use an Arduino is because it's easier to use and lots of example code out there so stop worrying about it and focus on solving the problem with you brilliant code in processing Answer.: IMHO you can use use AVR studio to compile Arduino/Processing Code IF you can port all the supporting files to work with AVR Studio. There is no code translator as such for converting processing to CPP but then they are just encapsulations. I think now a days everything uses the GCC compiler for AVR so it will not make that big of a difference. One alternative I can suggest is using Eclipse and control the entire process of building code.
