Hi,
I am using a ATMega32a to control VTS-08B servo motor.I am using the microcontroller with a 16MHz external crystal.
Low fuse byte=0XFF High Fuse byte=0XC9.Here is the code..
What happens is when the servo is powered it rotates to 0 degree initially from wherever it starts....after that it doesnt move at all.but I do get a weak sound of something vbrating inside the servo...What may be the problem?Or is it something wrong with the pulse duration?

_delay_ms(1000);
