Running servo motor with STM32

• Servo runs at 20ms(50Hz) with ‘0' position having 1ms HIGH and ‘180' position having 2ms HIGH

• We have to change the pwm frequency of stm using the command timer.setPeriod(20000) (20000us)

•   HardwareTimer timer(3);
  
    float pos = 0;
    double pwm = 0.0;
  
    void setup()
    {
      timer.setPeriod(20000);
      pinMode(PB1,PWM);
    }
  
    void loop(){
      //pwm = (1.0 + pos/180.0)*3276.8;
      pwmWrite(PB1,4733); //pos = 80
      delay(1000);
      pwmWrite(PB1,6553); //pos = 180
      delay(1000);
    }
