The AVR "ICE CUBE" jtag adapter from www.ecrostech.com plugs (via
a simple adapter) into the expansion slot of an STK500.
Works great ! Price ~$40-$45 depending on which adapters you
choose to include. Ron

Assuming you've read the data sheet and the resources of this MCU are
adequate to the job, yes, this is a reasonable platform.

Yes. Although you can't kick off builds from inside AVR Studio, it
does detect that the load file has changed due to a build kicked off
from somewhere else (Programmer's Notepad or the command line) and
reloads the project.

Note that there is no in-circuit debugger in the setup you're
proposing. The ATmega32 supports OCD via the JTAG interface, but
there is no JTAG header on the STK500. You will need two additional
things, first a JTAG interface and second some kind of adapter to
connect it to the STK500. The Atmel JTAG interface, the JTAG ICE, is
about $300, but if this is outside your budget there are "clones"
available which will do the job for you. It isn't too hard to puzzle
out how to make the adapter. If you get a clone JTAG interface you
may be able to get a ready-made adapter along with it. When you move
from the STK500 to your own target system, remember to build in the
JTAG header.
