Hello All,

I am trying to control a servo motor using a PIC12F675 with a toggle switch=
.. When the switch is one state, the servo goes forward and the other state,=
 the motor goes reverse.=A0

Here is something that I tried:

_CONFIG(WDTDIS&PWRTEN&MCLRDIS&BOREN&UNPROTECT&INTCLK);
#define_XTAL_FREQ4000000

voidmain(void){
TRISIO=3D(1<<3)|(1<<4);
while(1){
if(GPIO3)
{
GPIO=3D(1<<2);
__delay_us(900);


GPIO&=3D~(1<<2);
__delay_us(100);
__delay_ms(19); //here the total time pulse is 20 ms including ON time



}
if(GPIO4)
{
GPIO=3D(1<<2);
__delay_us(2100);


GPIO&=3D~(1<<2);
__delay_us(900);
__delay_ms(17);

}

}
}

My main need is that the servo should spin in opposite directions whenever =
the switch changes state. The motor changes position only once and nothing =
happens after that.=A0

I am not able to find out what is wrong here. I also tried making the motor=
 move in opposite directions without any switch control. The servo does not=
 spin as it should. It stays at the same position and makes some jerky move=
ments.

I am looking forward to your suggestion regarding the same.
