    hi guys and girls

    i hope you gurus could point me in the right direction

    i am putting together a goto telescope project

    i have built the encoder circuit it communicates via serial port ( no problems )

    my intent is to use stepper drives of the shelf these are parallel input

    the problem lies in that the astro software outputs in serial or ethernet not parallel

    any suggestions as to the easy way to control the drives

    the astro program is stellarium

    scope control via

    stellarium scope

    using these drives

    any pointers would be welcome

    side note

    i read the forums and have gained a lot from the wealth of knowledge thats
    flows across

    While your encoders use a serial I/F -
    Your stepper controls are neither parallel nor serial in the sense of an interface. The inputs are:
    - not at all the same thing as a parallel interface.

    You will have to take the output from the software package and use a microcontroller (you could do this in logic, but it's also a pain) to interpret the serial output and generate the direction and pulse signals for the stepper controller from that.
