Controlling a Servo motor using interrupts without servo library

i have been trying control servo motor without servo library due conflict in library using.

a problem have been running servo motor jitters unless send frequency.

i figured use interrupt control servo way sent same frequency , therefore not jitter.

i have never worked timer interrupts before working on dummy code make sure understand it.
here have:

code: [select]

#include <timerone.h>

void setup()
{
  //initialize digital pin output.
  pinmode(22, output);
  timer1.initialize(10000); //set timer of length in microseconds
  timer1.attachinterrupt(timerisr); //attach service routine here

}

void loop() {
  // put main code here, run repeatedly:

}

void timerisr()
{
  //toggle pwm
  digitalwrite(22, !digitalread(22));
}


the problem approach pin high , low equal amount of time changing frequency , not position.

is possible have high 30% or 90% of time corresponding position staying @ same frequency?

thanks in advance

have tried servotimer2 library?

the standard servo library uses timer1
