Working with AVR studio on arduino

Hello.
I new in embedded programming, i bought Duemilanove and whant to start develope some things. But, working with studio from arduino.cc it is no so good, much better AVR studio of Atmel.
Can i work with AVR studio on arduino Duemilanove ?
thank you

Maybe it is forbidden.... If it, so tell me please

Yes you can use AVR Studio. You will need a programmer like an ISP500 to program the chip (I don't think you can use the USB cable, correct me if i'm wrong) and you will also need to erase the chip to get rid of the bootloader. Once you do that it ceases to truly be an Arduino but the device will still work fine.

Once you start to use AVR Studio though you will need to use GNU C which is not as easy to use as the C in the Arduino IDE. Remember that you can use exactly the same C language using the Arduino IDE, although it is obviously not as feature rich as AVR Studio.
