The ATAVRDRAGON is an development tool used to debug AVR microcontrollers, AVR Dragon is fully supported by AVR Studio. The AVR Dragon sets a new standard for low cost development tools for 8bit and 32bit AVR devices with on chip debug (OCD) capability. It can perform a symbolic debug on all devices with OCD with SPI, JTAG, PDI, high voltage serial programming, parallel programming, and aWire modes, and supports debugging using SPI, JTAG, PDI interfaces. AVR Dragon supports all programming modes for the Atmel AVR device family. It also include full emulation support for devices with 32kB or less flash memory. A development area lets designers build their own circuitry or add sockets for the desired device footprint. The debugger also supports NanoTrace, depending on the OCD module on the AVR device, using the target device"s memory. AVR Dragon is powered by the USB cable, and can also source an external target with up to 300mA (from the VCC connector) when programming or debugging.
● Supports up to 3 hardware program breakpoints or 1 maskable data breakpoint
● Supports up to 32 software breakpoints
● On board 128kB SRAM for fast statement level stepping
● Robust level converters support 1.8V to 5.5V target operation
● Uploads 256Kb code in ~60 seconds (XMEGA using JTAG interface)
● Full-speed USB 2.0 compliant host interface (12MB/s)
● Firmware upgradeable for supporting future AVR devices
● Supports NanoTrace
● USB powered, and capable of sourcing power to an external target
●If the target board is powered by external power source, no connection should be made between the VCC connector and the external board.
●There is no CD shipped with the AVR Dragon. The only way of getting the software is by downloading it directly from the Internet.
