Question
write a program to spin the stepper motor. activate bits 1, 2, 4, and 8 in sequence to energize the electromagnets in turn. The motor can be half stepped by turning on pairs of magnets followed by a single magnet followed by a pair and so on. Please use the file below:

Explanation / Answer
In c languaged am writin g tis :
I m using following c program:
#include<reg51.h>
void main()
{
while(1)
{ void delay (int);
P1=0xCC;
delay(1);
P1=0x66;
delay(1);
P1=0x33;
delay(1);
P1=0x99;
delay(1);
}
}
void delay(int a)
{
unsigned int x,y;
for(x=0;x<10;x++)
for(y=0;y<a;a++);
}
If it steps 2 degree and you want 80 degree then 2 * 40 = 80. Use a counter and count from 1 to 40 and stop the execution of motor code if count is > 40. i.e., put you motor code inside if(cnt <= 40) and before that initialize cnt to 1.
