AVR-Chat

Sorry to jump in so late in the thread


One option is to use this opensource platform I've worked on
with a bunch of other people

it's called arduino (http://arduino.cc). it works with an atmega8
our manufacturer sells a single usb board for 20EUR plus shippping
but all the eagle cad files are provided if you want to make your own

it can also be used in a breadboard following the instructions
written by tom igoe from nyu
http://arduino.berlios.de/index.php/Main/StandaloneAssembly

The ide is written in Java and works on all major platforms and
the language is basically c with all the complications taken away

when you compile, your code is turned into c and compiled
with avr-gcc. when you get familiar with c you can start
going straight into the language.

jsut to give you a reference I'll cut and paste the classic led
blink example


int ledPin = 13;                 // LED connected to digital pin 13

void setup()                    // this is where you setup the pins etc
{
   pinMode(ledPin, OUTPUT);      // sets the digital pin as output
}

void loop()                     // by convention loop is executed  
forever
{
   digitalWrite(ledPin, HIGH);   // sets the LED on
   delay(1000);                  // waits for a second
   digitalWrite(ledPin, LOW);    // sets the LED off
   delay(1000);                  // waits for a second
}


I use it to teach designers about microcontrollers so it must be
super simple because they don't have any background in programming
or technology
