AVR Dragon Still The Best?

[Robert L Cochran]

Is the AVR Dragon the best choice of programmer? Or the STK500? I
checked a thread on this subject from last year begun by Vincent
Trouilliez (vincent.trouilliez@...), and it looks like a lot of
people like having one, or the other, or both programmers. Right now I'm
using a programmer which is proving unreliable, and I'd like reliability
while I'm in learning mode.

Thanks

Is a "programmer" all you want?  If so, both the AVR Dragon and the STK500
have a lot of stuff you'll be paying for but won't need.  You can pick up an
Atmel programmer more cheaply or a perfectly good third-party programmer
even cheaper
(http://www.avrfreaks.net/wiki/index.php/Documentation:Avr8ProgInterfaces).

The STK500 is also a development system.  It has switches, LEDs, a serial
port, a data Flash, configurable clock sources, an adjustable power supply
and an expansion connector for which you can get a plug-in prototyping board
(http://www.ecrostech.com/AtmelAvr/Stk500Exp).

The AVR Dragon is also an on-chip debugging interface.  For that reason,
plus it's cheaper, I would personally recommend it over the STK500 (I have
both).  You can turn the AVR Dragon into a sort-of development system with
the Dragon Rider (http://www.ecrostech.com/AtmelAvr/DragonRider) or just
cable it up to your own target.
