I did everything as in datasheet but i didn’t get anything but a burning smell. No commitment taken to produce Proposal: Yanking a few amps from a parallel port can permanently damage the port, dxtasheet not more.

I build it again but this time without Ln and and i put 4 leds to the output of the L It can be useful to make this signal jumper-selectable as sometimes switching transients on the Vsense voltages can cause the chopper to function at a frequency that is a division of the desired chopper frequency and resulting in an audible hissing sound from the motor.

With this pin un-connected, the controller cannot function correctly and it is very possible that it has caused the L to stay on and burn out. Not Recommended for New Design.

L297 Stepper Motor Driver IC

Limited Engineering samples available Preview: There are lots of examples for driving stepper motors via Propellers, etc. Datasgeet circuit should perform acceptably with this line either tied to logic high 5V or logic low GND. BTW I also haven’t connected anything to pin 17 and 18 because I know they are inputs. A dxtasheet of this device is that it requires only clock, direction and mode input signals. Marketing proposal for customer feedback.

You can make a simple stepper using a momentary switch, and tying the other inputs low or high, depending on the action you want e. Grove-compatible circular 24 LED array, ideally used with a rotary encoder input. As you datasbeet see on the diagram on page 2 of the L datasheet, this is the reference voltage which goes to internal comparators and is compared to the voltages coming from the current-sense resistors.

Can someone please tell me what did i do wrong? If you find any of the answers here or in any of the other questions you have asked useful, you might consider up-voting them.

A feature of this device is that it requires only clock, direction and mode input signals. Selectors Simulators and Models. Ruby, you might also get more attention if you go to your top posting, click on Vatasheet, then in the next window click on Advanced, then find the little drop down menu for Prefix and click on Unsolved. I am reading the datasheet again and please check me if i am right.

Have you considered using a Propeller or other chip for the controller rather than going directly from a computer port?

Just check the things i wroteleave the pictures. No commitment taken to design or produce NRND: Also from the L datasheet: I will need to change my software but at least now the first part is working and more important i understood how it works If you’re using a 5V supply it will get warm.

A failure of the L often results in a failure of the L and could be why it is getting hot. Personally, I have no idea how to control parallel ports on computers, but I’m sure somebody here knows how to do that. The motor can be driven in half step, normal and wawe drive modes and on-chip PWM chopper circuits permit switch-mode control of the current in the windings. Note I just made a correction to the fixed resistor value.

Cloud Components and Modules. You Might Also Like [ Hide ]. L2297 am gonna give a try again but what do u think about the post that i wrote ; the one with the pictures?

Do you have a link to the type of motor and motor specs? First i want to check L all alone. My problem is that I don’t really know what the Vref, control, sync and home pins do in this cirucit and what they connect to, and because of this I haven’t connected anything to them when testing my circuit. If it came from your PCs parallel port, that’s a major uh-oh. The transistor is open when this signal is active.

You really need to use the datasheet: Maybe there is a short from pin 4 on the L dqtasheet somewhere else. One end of the potentiometer goes to the 40k Ohm resistor I recommend the CW pin of the potentiometer. Doesn’t matter high or low for now Clock: If it’s getting hot quickly with a 5V supply, it’s probably wired wrong. Who We Are Management.

I just checked with the multimeter and pin 4 on the l is not short circuiting with anything else on the other pins of both the l and the l Why can it be?
