quickstart guide for engineers needed - atmega8 and C | AVRclub

Hi, I need to learn programming AVRs for a battery charger project. I've programmed other micros in asm and C. For the atmel i only want to use C (Winavr). I have here a atmega8 which i tried to use with the software from <http://zebra.tky.hut.fi/~jap/Electronics/AVR/Hello/>. I changed the device in the makefile and also the ports where the LCD is. Then i used make to get the hex file and avrdude to programm it which terminated OK. But i see nothing at the hardware. I have tried to toggle a port in a loop in main too, but i see no action with the scope (i have set it to output, yes). I think i missed something important. Should the code from the example run when i program it? When? I mean i tried power-off and on again, and i messed around with the reset pin, still no action. Shouldn't there be control register set or something? with stuff like clock source etc... Is there a good guide somewhere how to get started? All i found lingered for pages on useless stuff like installing the software but didn't follow through until programming the device. You see, usually i avoid using micros because i know i will get frustrated with something i don't understand fully. With other hardware i always know what i can do, use the scope or something, but with software stuff i'm lost. Thanks a lot for any help. ST
