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 signals, direction, decay mode(fast / slow) and a pwm (...)
You should always use the device header file that is installed with your compiler, so your configuration bit settings appear to be correct in this case. What version of the Hi-Tech C Compiler is installed in your system? Version 9.70? It might be time to update your compiler. Can you post the schematics as Alex suggested? Also what oscillator f
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 trying to use microstepping techniques. Because the motor is 5V, pwm output of the (...)
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 motor datasheet. Thanks in advance... Hi, The duty cycle is u

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 the motors??? PLEase:-D:-D
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 and tried all possible pulse sequence.(24 different combi
hey insight i think that u r making a gravity free room (1). make pwm for ur solenoid __mosfets better. easily implimented by small pic mcu with switcher (2).focous of force is by ur solenoid pole ::to the plate it likes to kiss (3).make some stepper motors adjustment for angle something __________once a time when in childhood i make a solenoid hol
Look in picAXE Manual - part3, section -output-device-6==>unipolar-stepper motor .. IanP :wink:
sir iwant c sourse code for driving 48 step bipolar stepper motor using pic & L298 with out using L297
i have it in ARM7, do you want it, it has 4 IR sensors , 2 stepper motors, GSM
I want to control the speed of dc stepper motor using microcontroller. The running speed of motor is display on PC (Labview) using usb interface. The difficulties are: 1. how to interface usb 2. how to display speed in labview
a complicated method would be to use a stepper motor coupled to a pot. who's Fragrance by the way ??
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 clear. Pullup at which pin?
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.
i am new in pic microcontroller. we are using pic16f628a. how can we drive the unipolar stepper motor using the pwm of the pic16? do anyone have a simple program using c for it? we are running out of time...tnx
i need to use ucn5804b ic to control my unipolar six wire stepper motor. but i still confuse how to use the pic to control the ucn5804b. anyone can give me some simple code for high-tech C language for pic to control the ic?? for the protection diode is it necessarily for use?
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
