AVR Dragon Development Tool


Atmel has introduced a small and inexpensive development tool called the AVR Dragon. This USB device can be used as an AVR programmer and emulator. The documentation for the AVR Dragon is part of AVR Studio. I pulled the AVR Dragon specific information from AVR Studio. You can get a pdf of that information here.

AVR Programming

The AVR Dragon doesn't come with even a socket for programming, so extensive modifications to the tool will be needed. The Dragon supports In System Programming (ISP) via a "standard" six pin ISP connector. This six pin connector is the ISP connector that I commonly use in my AVR-based designs.

The Dragon also has a High Voltage Serial Programming interface, a Parallel Programming interface, and JTAG. I have a number of AVR devices (ATtiny26) that have fuse settings that need to be correctly reprogrammed, so the Parallel Programming mode will come in very handy.
