Hello! You have to use if motor_status == 0 then stop_motor() No! This is a stepper motor. It does not run permanently and you don't have to stop it. However, about the program: 1. The function run motor() will do 4 steps at once. This is a waste: you buy a 400 steps per (...)
DC motor RPM is high. How will you get exactly 360 deg rotation? How will you know when to stop the motor? You can have angle control with stepper motor.
I've written a code in MPlab, the compiler im making use is C18 and i want it to do as follows.. Once we started the process, TIMER in pic 18F4550 and also Ultrasonic sensor(HC-SR04) must be triggered. If obstacle is detected by the sensor,the present value of the timer have to be taken for calculating distance between obstacle (...)
Dear friend, Im new in microelectronics and need some help or recommendation to design stepper motoro pulse controller. In attachment can see some graphics design which type pulses I need. In pic. Version_1.png its like Pentagon stepper motor (unipolar) Drivers Designs. obr
I'm working on a stepper motor driver, most of the control will be handled by a pic most likely a 16f887. I want to simplify control of the H-bridge switches to use fewer pins and make programming easier for the pic so I came up with the circuit below. The H-bridge needs only a few (...)
Hello Dear All, I have a unipolar 5V stepper motor and I want to drive it with a 16f877a. I have connected 2 pieces of tc4427 mosfet drivers and 4 pieces of IRF2807 to the pic and, as I see they are working properly. I supply 50V to the motor and I am (...)
I want to control a stepper motor through pic. stepper motor is in bipolar mode. What should be the minimum pulse width(ON time and OFF time or frequency and dutycycle) needed for control..I couldn't find any details regarding this on the stepper (...)
what is the rating and specification of the stepper motor??? your component selection depends on the rating of the motor......
hi there i am working on a project to control two stepper motors from a pic16f690 using L297 stepper motor controllers adn uln2075b quad darlington transitor ic. i having difficulty with the c code to control the motors from the pic can anyone help me with C code to control (...)
Hi there.. I have a few stepper motors.All of them are 6 wire unipolars. I m using pic 16f877 and a power circuit which has L298.(not L297 ) I could run one of them succesfully using 1000,0100,0010,0001 pulses.But I couldnt run other motors,although I identified the wires using multimeter (...)
you may want to check out for their stepper motor driver projects.
Hi silencer80, First of all, you cannot use ULN2003 for a BIPOLAR stepper motor since it can only sink current and can't source current. You may use L293D instead and it is rated for 600mA continuous. 'do I need pull up resistor at the input of the pic' -please make the question little more (...)
hello friends , I would like to know that while using stepper motor in professional equipments ,do we just apply pulse high and low or there is acceleration given to motor from gradually 0 to max . Please suggest how to implement such thing in a program using pic microcontroller.
Hello all, What is synchronous stepper motor , and how to drive it . for example i have motor from superior electric , slo-syn type ss252b. Its steps are controllable or not. Regards Dani

Hi, I'm currently experimenting electronics as a hobby. I bought a protoboard, a pic programmer, some pic16F628A chips, some L7805 voltage regulators and some ULN2003AN chips. I have a small stepper motor I would like to drive using a circuit that uses (hopefully) these components. I have read a lot (...)
first u need to know how stepper motor can be interfaced with microcontroller pic or any. there r different kinds of stepper motor available. what kind do u have? 5wire, 6wire and u must also know the step angle. after that u need to give pulses to the motor either in (...)
Hi, It depends on exactly what you are trying to do and what type of motor you are trying to control ? - dc brush motor, stepper, servo etc. Each type of motor needs a different method of control from the pic - which one are you using ? You can change direction of a dc brush (...)
hi, i have a project that about dtmf based stepper motor control via 16F877. when i pressed 4, the stepper motor turn anticlockwise. 6; turn the clockwise and 5 is stop the motor. how can i do this? anybody help me?
in this i am using pic 16f88 both at transmitter and also at the receiver . so i need code please
Hi guys, i just recently succeeded with functioning stepper motor with pic and UCN5804B, so i just did a fundamental test on stepper motor by pumping in different speed in the coding, but with 50% duty cycle. So i tried with 16ms period until 1.5 ms period, so 16 ms makes the (...)
hey, I'm currently using the SLA7062M unipolar stepper motor driver/translator . I' would like to ask as about that, how can i control this chip with microcontroler-pic. I use the pic16F876 and i've clock frequency 10MHz for timing. So, the instruction word is tc= 0,4 μsec. More over, i saw the (...)
You can use "pic simulator IDE" There is a version for 8051 also This software got stepper motor indicator ( 2 coils) Got basic and assambler as compiler.
hallo, i need a programm to control stepper motor with stepper motor controller tmc239 and pic 18f4580.I have written a programm but i didn't work at all.troubleshooting my programm has not yet been successful.thx regards, Bruno Kasimin
Hey you can write a program for keypad interface and read the digit/value entered. simply use this as your angle or speed or what ever you wish and run the stepper motor code after u press say ENTER on keypad or when a valid no. is entered.
Hi, I need to interface my pic 12-hour clock to another pic stepper motor controller, had anyone here has a simple schematic for me? What I want to do is to set a time for the clock and at the moment the stored time exacts the current time , the stepper motor will rotate (...)
It so simple to drive a stepper motor bro. Try ULN2003 or BA motor driver from ROHM.
Its rather very simple. Connect your stepper motor to the pins named Output(A-D). From you pic you can control direction and step inputs. Just set the direction to 1/0 and then pulse the step pin everytime you want your stepper motor to move. You can also do the same in (...)
I want to drive some stepper motors and I´m thinking to control their currents with a pic (also becouse I´m going to use a pic to control each motor) so what do you think? Use a pic to control the current limit or use a simple circuit as something as easy as a resistor (...)
Hi I am having a bipolar 12V 0.6 AMPS 1.8degree stepper motor.I am having problem in finding the driver circuit. and secondly If i have to control it using the signals from the pic how am I going to do it?????/ Any circuit diagram or any related information will be really helpful Kind Regards Quium
Dear all, Do any one have data pattern to interface the stepper motor SM-E040 to a pic controller. Thanx Hello, The SM-E040 is an Epson stepper motor, No??? Well, I think it is and if I have to make a design with it, the first choice is build something like Epson do. They (...)
A preview: Have 6 unipolar PM 4-phase stepper motor, how can I drive them?! I will use a micro (as a pic or so). I have thought use 4 chips 1:8 DeMux to send them the 4bits signal (see Image 1) or use 3 1:8 DeMux to send a 3Bits signal to the driver (Enable, clock signal and direction) This option may not be able becouse (...)
if u want then u have to design ur self you take joy stick and then connect the upper and lower switches of the joy stick to the stepper driver card for forward and reverse direction selection of the stepper motor it is very easy ....... if u want any assistant to design (...)
hi guys. im trying to do a project. the last project i tried to do failed and didnt work due to my lack of understanding the 8051 and missing a lot of things. my last project was something like this. i wanted to communicate between two cars, which would communicate with each other and the lcd display in each car (...)
You would have to find a stepper motor controller to control the motor. The controller would be controlled by the pic. The best way to do it is using pic's timers and interrupts to generate pulses to the motor controller. Depends what frequency you need to move the (...)
