how to program bipolar stepper motor using P18F4580..

i have a stepper motor but i did't know a polarity of wire,green,red,blue and yellow.

and how to program it in P18F4580.. :roll:
 

can you give a programing code to run stepper motor.
 

Hi friend

First of all, To run stepper motor,

you need, Stepper motor driver circuit.
do you have any driver ckt.

To detect Polarity of wire,
Take Multimeter and check continuity of any two wire.

if it display continuity, that two wire are pair.

With multimeter you can find the pairs but not polarity of the pairs.

If you cant find the datasheet you have try different combinations swaping the wires
 

Dear friend

Here i post a program for rotate a stepper motor

oid main()
{
int i;
TRISB = 0x00;
PORTB = 0x00;

//routine to move in one direction
while(1)
{
for (i=0;i<50;i++)// increse i=50 no i=100 to cover double the distance
{
PORTB=0x08;
Delay_ms(200);
PORTB=0x04;
Delay_ms(200);
PORTB=0x02;
Delay_ms(200);
PORTB=0x01;
Delay_ms(200);
}
Delay_ms(400);
//routine to move in the other direction

for (i=0;i<50;i++) // increse i=50 no i=100 to cover double the distance
{
PORTB=0x01;
Delay_ms(200);
PORTB=0x02;
Delay_ms(200);
PORTB=0x04;
Delay_ms(200);
PORTB=0x08;
Delay_ms(200);
}
}
}
 

I put the four light sensors at 90degree,180degree,270degree and 360degree. I want to rotate the motor stepper to the sensor readings that high value of reading.
it is possible to do like that???
 

Dear friend,

Yes it is possible one.You just read the value from your light sensor.

Yes, but you need to know how many steps does your motor need to fully rotate, then you can program it in Pic.
And that's why data sheets was made for.
