Atmel JTAG ICE and STK500

           I am a newbie to microcontroller programming and seek your
advice. I have a old and used but working ATMEGA32L processor board
designed for some application. And I have a JTAG ICE from Atmel. I was
given this board to learn about microcontroller.
           After searching the web, I found this STK500 which claims
to be the tool for beginners. And I bought a book "embedded C
programming and atmel avr" which gives some programs with blinking
           My question: Being an absolute beginner to the world of
embedded programming, should I go and buy the STK500 kit or can I
understand with the JTAG ICE and the board I am having (it doesn't
have any LEDs but I do have schematic of the board).
           Please advice what is good for a beginner so that I don't
get frustrated but more interested in the beginning, and I can save
time by learning towards right direction.

Thank you

I tell you what :-)

You send me the JTAG ice and I'll send you the STK500.

The STK500 is great for a "first board" since it

- brings all the ports out to easy to grab 0.1" headers

- has headers for on-board LEDs and momentary contact switches

- has an RS-232 lever shifter and standard 9-pin connector (in addition
to the one for the programmer)

- has sockets to support all (AFAIK) DIP form-factor AVR devices and
takes care of clock and power

- can parallel program devices that support it, which can save the day
if the wrong fuse is blown and the chip won't talk serial programming

- and can also be used as an in-system programmer for devices on other

Still, most of the time I find the little AVRISP is easier to use since,
even on a breadboard, it's much simpler to leave the chip in-circuit
than to keep swapping it to a separate programmer.

Having the JTAG ICE device, you really don't gain much by having the
STK500 that you can't do with a breadboard, power supply, and clock.
