Steper motor control with 8051 and L293d brdige

[chethankp]

Hi , I ordered online for stepper and its driver , I got the stepper motor (attached the snapshot1 ) and HBridge for the same (snapshot2) .

I do not know the pin details of stepper motor to integrate with Controller ..

Can you pls suggest how can I connect this with the L293d brdige and 8051 controller .

Hi,
What kind of a stepper is this?, I mean do you have the specification of the stepper? Anyway have a look here...

Hi , I just received this motor .. Nothing is mentioned on the motor .. I went through the link and I connected the motor .

It just rotates one step forward and backward .. Actually I need clock wise full rotation

below is the sequecence I am sending

P1 = 0xF9;
delay(100);
P1 = 0xFC;
delay(100);
P1 = 0xF6;
delay(100);
P1 = 0xF3;
delay(100);
P1 = 0xFC;
delay(100);
P1 = 0xF9;
delay(100);
P1 = 0xFC;
delay(100);
P1 = 0xF6;
delay(100);
P1 = 0xF3;
delay(1000);

Program for full step (full clockwise rotation) is given here, https://www.8051projects.net/stepper-motor-interfacing/programming-microcontroller.php

just tweak a bit...I think you get it...

hi
to rotate stepper require clock to rotate with one step.
if you are giving continous clock to stepper motor and keep the direction of motor pin is +/- as per rotation then it will rotate. again if u are using driver on 800/1600/.... steps/rev
then u will need to give that much clock to stepper motor.
