AVR Dragon - Low Cost Development Tool for AVR Microcontrollers
The AVR Dragon sets a new standard for low cost development tools. AVR Dragon supports all programming modes for the AVR device family. It also includes complete emulation support for devices with 32KB or less Flash memory. The AVR Dragon can be used with an external target board as well as an onboard prototype area, allowing programming and debugging without any additional hardware.
Supported AVR Programming and Debugging Protocols
- In-System Programming (ISP) 3-wire AVR programming protocol
- High Voltage Serial Programming
- Parallel Programming
- JTAG Programming 4-wire IEEE 1149.1 compliant JTAG interface
- JTAG debugging Available for devices with up to 32 Kbytes Flash
- In-System Programming
- debugWIRE One-wire AVR debugging protocol
Emulation Interfaces
PC communication and power by USB - No external power supply required
AVR Dragon is powered by the USB cable and can also source an external target with up to 300 mA for programming or debugging. If the target is already powered by an external power source, the AVR Dragon will adapt and level convert all signals between the target and the AVR Dragon.
AVR Studio - Complete debugging environment with C-compiler available free of charge
The AVR Dragon uses the AVR Studio IDE available free of charge from Atmel. AVR Studio includes a simulator, assembler, and C-compiler and is the software front-end for all Atmel AVR debugging and programming tools. A flexible and secure firmware upgrade feature allows AVR Studio to easily upgrade the AVR Dragon to support new devices free of charge.
