Hi there..

Until now i have used the PIC16F84 for my embedded projects, but a 
friend of mine told me about the atmel AVR, which looks very nice 
compared to PIC's. My questions is:

First im looking for a tutorial or a good book on asm/c programming the 
atmega8, so I can get started :)

Im also looking for some useful information on building a programmer 
which works under linux/bsd

And lots of other useful information ;-)

Toke Jansen

P.S is there any irc channel for embedded systems?

UISP with 4 wires from the parallel port to the chip!

I have a AVR intro on my embedded page :
http://milkstone.d2.net.au/embedded.html
Including a full howto on installing the toolset under GNU/Linux.

http://milkstone.d2.net.au/electronics/micro
/avr-gcc-installing-2003.html

I have just set up the avr-gcc environment under GNU/Linux (Gentoo)
including the avr-gcc C compiler,  simulator, and burner.

My first mega8 was a piece of cake to burn and is running my first test
program as I type this.
 
> And lots of other useful information ;-)

The main site for GNU/Linux is http://savannah.nongnu.org/projects,

I wouldn't waste your time with Avrfreaks as it's too Windows centric to
be a lot of use to GNU/Linux users setting up the toolset, though
code examples etc may be of use ?

Check out AVRDUDE:

	http://www.bsdhome.com/avrdude/

Note the simple parallel port cable programmer on that page.  We just
released version 4.2, you can find the source tarballs and rpms here:

	http://savannah.nongnu.org/files/?group=avrdude

If you are using FreeBSD, all the AVR tools are part of the "ports"
system.  For example, to install the compiler (avr-gcc), programmer
(avrdude), avarice (jtag enabler), avr-gdb (source level debugger), and
simulavr (simulator), just do this:

	% cd /usr/ports/devel/avr-gcc && make install
	% cd /usr/ports/devel/avrdude && make install
	% cd /usr/ports/devel/avarice && make install
	% cd /usr/ports/devel/avr-gdb && make install
	% cd /usr/ports/devel/simulavr && make install

I happen to sell couple of AVR boards with the ATmega128 processor (top of
the line AVR).  You can find that here:

	http://www.bdmicro.com/

For some more info on AVR tools, take a look at my "dev tools" page:

	http://www.bdmicro.com/devtools/

Good luck!
