►Programming Full step Sequence

►C Programming
I am assuming that stepper motor is connected at Port 1.0 to Port 1.3. Adjusting the delay will increase or decrease the speed of the motor. Here just for demonstration i have taken some delay, you can change it as you want.

[Tip: Do testing.. ]




#include <REG2051.H>
.
#define stepper P1
void delay();

void main(){
	while(1){
		stepper = 0x0C;
		delay();
		stepper = 0x06;
		delay();
		stepper = 0x03;
		delay();
		stepper = 0x09;
		delay();
	}
}

void delay(){
	unsigned char i,j,k;
	for(i=0;i<6;i++)
		for(j=0;j<255;j++)
			for(k=0;k<255;k++);
}



►Assembly Programming

	org 0H

stepper equ P1

main:
	mov stepper, #0CH
	acall delay
	mov stepper, #06H
	acall delay
	mov stepper, #03H
	acall delay
	mov stepper, #09H
	acall delay
	sjmp main

delay:
	mov r7,#4
wait2:
	mov r6,#0FFH
wait1:
	mov r5,#0FFH
wait:
	djnz r5,wait
	djnz r6,wait1
	djnz r7,wait2
	ret
	end


The working of the above code can be seen in the demo animation below.

►Programming Half step Sequence

►C Programming
Just the main routine changes rest everything remains same, i mean same delay routine.


void main(){
	while(1){
		stepper = 0x08;
		delay();
		stepper = 0x0C;
		delay();
		stepper = 0x04;
		delay();
		stepper = 0x06;
		delay();
		stepper = 0x02;
		delay();
		stepper = 0x03;
		delay();
		stepper = 0x01;
		delay();
		stepper = 0x09;
		delay();
	}
}



►Assembly Programming
Here also the main routine changes rest everything remains same.


main:
	mov stepper, #08H
	acall delay
	mov stepper, #0CH
	acall delay
	mov stepper, #04H
	acall delay
	mov stepper, #06H
	acall delay
	mov stepper, #02H
	acall delay
	mov stepper, #03H
	acall delay
	mov stepper, #01H
	acall delay
	mov stepper, #09H
	acall delay
	sjmp main


The working of the above code can be seen in the demo animation below.

@Ben, Its hard to undrstand the context like this. If you can post in forum with some example code we might answer you better.
