    stepper motor controller

    hi,
    I have 2 stepper motors to be controlled by dspic. I have programmed the pic. Im confused in usng L298 s. Can someone help me with a circuit diagram for stepper motor controller?

    How can I implement micro stepping in it? what ic can I use for microstepping. If there is a circuit diagram with micro stepping, it will be of great help for me.

    stepper motor controller

    use the SLA70762M stepper motor translator IC from Sanken, its a single chip, more robust than the L297/L298 pairs, it also occupies less space.

    You can also get 1/4, 1/8 and 1/16 step motion. The datasheet for the part contains a circuit diagram that describes the detailed operation of the device.

    I have myself used the same circuit to make stepper motor controllers for my projects.

    For a more advanced micro-stepping chip, try the Allegro series.

    There are also many stepper motor controllers that can be easily configured using a mcu or a PC.

    Re: stepper motor controller

    hi can a max233 can be supported an stepper motor?for example max233 can direct the rotation of the stepper?im dealing with the human motion tracking in matlab

    this is circuit you can get help from it...only some changings must be done in the pic the h-brigde is used LMD18245..



    if still confused feel free to ask....
