Dragon12+ board and stepper motor
through. I need help connecting the motor with the dragon board and its not
connecting together. Can someone please give me a quick tutorial on this
matter. Any help is greatly appreciated. Thanks so much
You are going to need to setup a driver board to amplify your signal (I'm assuming you know how to produce the correct signals from your board to run a stepper, yes?)
So basically, here's the deal...
The board can speak the language that the stepper needs to hear, but it speaks very softly and the stepper is hard of hearing. Drivers can act like megaphones...they don't change what the board is saying, they just make it a lot louder.
The board will output a 5V signal at low current. User drivers and an external power source to boost the voltage to meet the specs of your motor. Also, the external power source should be able to supply the needed current.
Sourcing too much power through a Dragon12+ board can break it! If this is too much for you to handle, ask someone for help! If you want a suggestion on drivers you might consider...look at L289's! They are very useful and easy to utilize.
Here is an example:
I'd also recommend a book called "Designing with Mirocontrollers" which uses the Dragon12+.
small stepper motors. You can jumper the driver to power it from a
separate supply. If you look on the Wytec website, http://www.evbplus.com/hcs12.html
, it shows the connection for a stepper motor. One winding connects
between terminals M1 and M2 and the second winding connects between
terminals M3 and M4. There is a demonstration program that will run
the motor that is provided on the CD that comes with the board.
