[dorkbotpdx-blabber] Does benito5 only program but not debug AVRs

[Dan Strother]

It's actually a clone of the previous JTAG ICE (
http://www.atmel.com/dyn/products/tools_card.asp?tool_id=2737 - now
replaced by the mkII, as you found on Digikey).

I think AVR Studio will do everything that you want, particularly now
that it integrates with WinAVR - though, I've never actually done any
in-circuit debugging of AVR's (only researched it a bit), so I don't
have any first-hand experience.

Good luck :)
