Hello,
I have reviewed the tutorial available here:
http
://www.8051projects.net/stepper-motor-interfacing/programming-microcontroller.php
and I have got my bipolar stepper motor to turn using the wave drive sequence where only one winding is energized at a time. However, I need increased torque so I was going to go with the stepping sequence that energizes two windings at a time.
The code that causes my motor to turn counter-clockwise using an 8051 and an L298N Dual H-Bridge is:
STEPPER EQU P1
MOV STEPPER, #0001B
ACALL DELAY
MOV STEPPER, #0100B
ACALL DELAY
MOV STEPPER, #0010B
ACALL DELAY
MOV STEPPER, #1000B
So that is the sequence I use. I need assistance, based on that correct sequence, what will the new sequence be to energize the correct 2 windings without blowing my H-Bridge and possibly my Voltage Supply circuit??
I believe the cause of blowing is if both windings of the motor are energized at the same time, but my sequence is different than many websites show, so my windings must be arranged differently so I can't follow their code exactly.
Thank you for any help!
