Dont Panic!

working with avr and pwm

I seemed to have a lot of trouble getting pwm code going. below is some simple code that got me going. looking back on it now I am unsure as to why I was having such problems. I think its because, arduino, port codes, and timer codes, and pwm codes dont exactly match and I wasnt looking at the reference material. anyways hope this helps.

int main (void)
{
DDRD |= (1&lt;&lt; PD3) | (1&lt;&lt; PD5) | (1&lt;&lt; PD6);
TCCR0A = (1&lt;&lt;COM0A1)|(1&lt;&lt;COM0B1)|(1&lt;&lt;WGM01)|(1&lt;&lt;WGM00);
TCCR0B = (1&lt;&lt;CS00);
TCCR2A = (1&lt;&lt;COM2A1)|(1&lt;&lt;COM2B1)|(1&lt;&lt;WGM21)|(1&lt;&lt;WGM20);
TCCR2B = (1&lt;&lt;CS20);
OCR0A = 0;
OCR0B = 100;
OCR2B = 255;
sei();
while (1)
{
;
}
}
