hi all,
since from the datasheet it shows atmega32L support until 4 PWM channel. So am i able to control until 5 servo in one time?

thanks.

Yes, has been discussed many times before. You actually only need one timer - the rest is done by software. There's probably examples in the projects section.

Use only one timer. You do one servo after another. You can do 8 servos and still maintain 60hz update. All interrupt driven with no software loops.
