Check out www.barello.net/ARC Look at the users guide.  The last page is a
schematic that contains the wiring for the "SAMPLE" programmer.  SAMPLE
programmer works with BASCOM basic compiler.  You can get BASCOM with a 2k
limit (and you can get a lot done in 2k) for free.  Once you have become
tired of BASCOM you can trade up to GCC C compiler (WinAVR from
www.avrfreaks.net) which has a programmer that works with the SAMPLE
interface (as well as a bunch other).

For populating your breadboard: get a mega8535, or mega16 or even a mega8.
They come with an internal 1 mhz oscillator enabled so you only need to
supply +5v, gnd and the programming cable.  Hook a couple LEDs to some
output pins (read the data sheets, read my introduction to BASCOM
programming) and you should be good to go.  Once you get a blinky light
going, then fiddle with the configuration fuses to enable the 8mhz internal
oscillator so things go faster.  Or, enable the external crystal and connect
a 16mhz crystal to make it go really fast.

You can do all this on one of those plastic breadboards with the grid of
holes for pushing jumper wires into.  Works great.  That is how I prototype
all my designs for the purposes of S/W development (the breadboards are not
too good for high power or accurate ADC stuff).

Cheers!

Subject: [AVR-Chat] Starting Out


Greetings,

Does anyone know what the best way to start out in AVR programming
is?  I've heard from a local hobbiest programmer that there was a way
to do a 6wire parralel port programmer, but I wasn't able to find
this from google.  Does anyone have a link to this, or other simple
programmers?   There doesn't seem to be a whole lot out there for the
student budget that I have been able to find.  Also any other advice
for begining avr programmers would be very appreciated.
