Hi,
found this Code, the orignal author is russian and so was the article. I have a spare ATMega8 and would like to put it on it. But the code uses timer/counter and PWM stuff, which is specific to ATMega328 family, can anyone help in porting it to ATMega8 specific timer/counters ?
here is the Code:

any help would be appreciated. Have already etched the pcb and populated it with other components.
