ATMEL AVR Hardware?

I have a pic, pic programmer etc. but I would like to get started with AVRs.

I see lots of information about the software side of AVRs but little about the
hardware side.

Where can I get one or two AVRs?
Where can I see an AVR Hardware related tutorial?
What is the best "starter" AVR with a hardware UART? The best one for me
would be one much like the pic 16F628.

atmel.com and there you will be directed to distributors.

www.avrfreaks.net you need to register, but that's free.

90S2313 is a 20 pin IC with UART, ADC and PWM and so on

Pick up an STK500 from Digikey or somewhere, about $80. It includes one
or two sample devices (not sure which ones they include lately).

Most of the AVRs have a hardware UART. The STK500 also has an RS232
driver (voltage shifter) and an "extra" DB-9 connector that goes with
it.

The Atmel site has good datasheets and application notes. In addition,
there's great info at www.avrfreaks.com.

If you're shopping for a midrange AVR, pick up a couple ATmega8 chips.

I second that. My STK500 came with AT90S8515 and ATMEGA16L chips.
The STK502 daughter card came with an ATMEGA128 chip. I'm using the
combo to prototype an alarm clock that sets itself automatically from
the NIST WWVB 60 KHz time signal. I'm using the AVR GCC tool chain port
and avrdude STK500 interface under Linux. I had no trouble getting up
and running quickly.

Have a look at the following boards:
http://www.futurlec.com/ATDevBoard.shtml
http://www.futurlec.com/ATMegaDevBoard.shtml
http://www.futurlec.com/ATMegaTraining.shtml
http://www.futurlec.com/ATMegaControlBoard.shtml

I am happy with my $19.90 at90s2313. board.
It can be programmed using winavr under windows
(http://winavr.sourceforge.net/) or gcc cross-compiled
for avr-coff under cygwin or Unix/Linux/*BSD, but you probably
already know this.

Note that the programming software I got with the board
works only with MS-DOS (real mode) or Windows 9x.
I don't know if they have a win2k or xp version available.

Cool! Thank you.

You are welcome!

Just in case, here is an excellent introduction to at90s2313 programming
with gcc
from Joerg Wunsh (http://www.sax.de/~joerg/).
I definitively own him a beer...

Good links. Thanks again. :)
