I recently installed Atmel Studio 6 and upgraded a project that had to be manualy recreated so I thought I'd document the process including use of an AVR Dragon. The first step was to create a new project and as my code was C++ I selected
GCC C++ Executable Project:
The next step is device selection, a search facility is provided that saves sifting through the entire list of devices:
The next step required for most projects is to define the CPU frequency. I went into
Project | Properties and went to the symbols tab for the compiler I'm using, in this case C++. There I defined F_CPU by pressing the add button and typing
F_CPU=11059200 to suit the crysyal I'm using. Once done the screen looks as follows (note that I corrected the value after taking the screenshot, it was missing a zero):
In the same area you can go down to the tool tab and define the type of debugger / programmer and the interface. In my case I was using the JTAG interface, different options will appear if using ISP but the defaults are normally OK.
Once that's been saved you can click on the device programming icon on the toolbar or press
Ctrl + Shift + P to get to the device programming screen.
Once you've confirmed the correct tool, device and interface is selected you can press the apply button to connect. It's likely the AVR Dragon will require a firmware update to work so press the upgrade button if prompted to do so and wait for the upgrade to complete.
Once connected you'll be able to read the device signature and target voltage to confirm the connection to the target is OK. You can also program the various memories, lockbits and lock bits from the same screen.
However once your configuration bits are have been set you may find it more convenient to use the start without debugging button on the toolbar to launch the project. That will automatically build the project if required, program the device and start the program.
