When it comes to low cost development tools, the Atmel AVR Dragon set a new standard of the 32-bit and 8-bit devices which have an OCD or On Chip Debug capability. It is capable of performing symbolic debug on all those devices which has SPI with OCD, PDI, JTAG, parallel programming, high voltage serial programming, aWire modes. It supports debugging using JTAG, SPI, and PDI interfaces.
Main Features of this programmer
Here are some of its main features. Have a look on the same:
Main Features of this programmer
Here are some of its main features. Have a look on the same:
• It supports 1 maskable data breakpoint or 3 hardware program breakpoints or (it depends on the OCD module on the AVR device)
• It is capable of supporting software breakpoint up to 32 which is quite good
• It comes with a 128kB SRAM, which is On-board and is required for fast statement-level stepping
• Robust level converters support 1.8V to 5.5V target operation
• Is capable of uploading 256Kb code in ~60 seconds
• It comes with a Full-speed USB 2.0 compliant host interface, which is 12 MB/s
• Firmware can be upgraded in order to support the AVR devices of the future
• It is capable of supporting nano traces. It depends on the OCD module on the AVR device. It uses the memory of the target device.
• It is powered by USB cable and power can also be sourced from it to any external target.
In this respect it is important to mention that Atmel AVR XMEGA PDI mode on AVR Dragon do not work for some of the XMEGA devices, like A3/D3 - revisions B, C and E or A1.
So, these are some of the features of this programmer and if you are willing to possess this tool, it is better to know all these specifications and functionalities before ordering one to serve your purpose.
