Welcome to the forum members!
I want to ask for a Jis help. Gave an Arduino mega, 8 Nema 17 stepper motors (4Wire) and 8 L298N motor drives.
How could I write a program to have 6 motors rotate directly automatically so I can adjust its speed from a pc and 2 motors to scan automatically, adjusting its speed. Thanks in advance too. P
The l298 is a really ancient driver. Are you sure that your steppers fits to it? Many steppers can not be operated with the l298.
You should explain a bit more. How do you want to adjust the speed from the PC. Is there programm running and do you know which protocol it uses? What do you mean with 'scan automatically' and who adjusts its speed?
You could use my MobaTools to drive your steppers. There are examples where you can start with.
'Out of the box' MobaTools supports only 6 steppers. But if you don't use other functionality like servos or bulb simulation it can be easily extended to support 8 steppers.
Works with L298N. By scan I mean that 360 rotates to the right, then 360 to the left. Port 9600
for me it also goes off if 6 engines are spinning continuously and 2 back there
how to assign multiple motors? 1 piece works with this code
should it run automatically, dmx and computer control is not important.
at the same time would start ming 8 engines out of 2 engines back there
Please don't post code as an image. Always post it as text within code tags ( the Button </> in the forum editor ).
Or in the IDE go to Edit->Copy for Forum and insert in your post.
The Stepper.h is not suitable to run several steppers at the same time.
/*
Stepper Motor Control - one revolution
This program drives a unipolar or bipolar stepper motor.
The motor is attached to digital pins 8 - 11 of the Arduino.
The motor should revolve one revolution in one direction, then
one revolution in the other direction.

#include <Stepper.h>
const int stepsPerRevolution = 200; // change this to fit the number of steps per revolution
// for your motor
// initialize the stepper library on pins 8 through 11:
Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11);
void setup() {
// set the speed at 60 rpm:
myStepper.setSpeed(60);
// initialize the serial port:
Serial.begin(9600);
}
void loop() {
// step one revolution in one direction:
Serial.println("clockwise");
myStepper.step(stepsPerRevolution);
delay(500);
// step one revolution in the other direction:
Serial.println("counterclockwise");
myStepper.step(-stepsPerRevolution);
delay(500);
}
works separately, I want to start at once
#include <Stepper.h>
const int stepsPerRevolution = 1000;
// initialize the stepper library on pins 8 through 11:
Stepper myStepper (stepsPerRevolution, 8, 9, 10, 11);
void setup () {
// set the speed at 10 rpm:
myStepper.setSpeed (10);
// initialize the serial port:
Serial.begin (9600);
}
void loop () {
// step one revolution in one direction:
Serial.println ("clockwise");
myStepper.step (stepsPerRevolution);
}
Please don't forget the code tags when posting code.
?? I don't see any try to drive more than one stepper. And I told you already, that Stepper.h is not suitable for that.
