    Controlling RC Servos

    HI All,
    i am using Futaba FP-S128 Servo motor for a project.
    I now that these servos expect a high-low stream on pulses of 0V and 5V going high for 1mS and low for 1mS. With this 2mS period. If both high and low have same time the servo remains in neutral position. So my changing on period to 1.5mS ON and 0.5mS off the servo moves clock wise, by reversing it i.e. 0.5mS ON and 1.5 OFF the servo moves counter clockwise.
    I need to know that for how much time I or how much pulses i should give the motor to move

    please Help!

    Re: Controlling RC Servos

    It is independent of the work time.
    Each duty cicle corresponds a position. If you want to move into an position send the appropriate duty cycle and motor will turn into the position corresponds that duty cicle. Then you can unselect pin or send continuously same duty cicle.
