STEPPER MOTOR QUERY

VIVEK SHETTY

HI I AM WORKING ON STEPPER MOTOR WITH MICROCONTROLLOR(P89V51RD2BN).THIS IS MY PROGRAM.
#include<reg52.h>

#define ST_CNTRL P1;

void delay(void);

void main()
{ unsigned char k; for(k=0;k<30;k++) { P1 = 0x66; delay(); P1 = 0xcc; delay(); P1 = 0x99; delay(); P1 = 0x33; delay(); }
}

void delay(void)
{ unsigned int i,j;

for(i = 0; i<0x20; i++) { for(j = 0; j<0x20; j++) { } }
} PROBLEM IS THE STEPPER MOTOR DOESNT STOP AFTER 30 STEPS AS GIVEN IN FOR LOOP.IT JUST JERKS AFTER 30 STEPS AND CONTINUE ROTATING,I WANT TO STOP IS AFTER 30 STEPS. CAN ANY ONE HELP?
