Code switcher

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. A tutorial on how to set it up is given at http://embeddedcode.wordpress.com

Thanks.

but still can anyone write a proper tutorial for not only me but others and will help a lot of them to save memory space and would be very grateful if someone told how to do it on chips which don't support arduino bootlader like atmega324pa etc.

this should be a good place to start   http://arduino.cc/en/Hacking/Programmer

Regards

Without the bootloader, you can program a chip using an In-System Programmer. I use http://dangerousprototypes.com/docs/Bus_Pirate_AVR_Programming

It's cheap(er) and can be used for many other things too.

Be careful and be sure to configure the flags right.

Hope this helps,
