An alternate solution is to google for one of the bazillion parallel port to stepper interfaces, or a PCB USB to stepper controller. Why re-invent the wheel when you can just use a PC?
One reason would be for existing instruments designed with USB device endpoints in them. Some microscopes already have USB drivers for controls and having a USB host could keep all that separate from the workstation. Have all the settings saved even if the workstation is turned off, etc. John -- Ecosensory Austin TX _______________________________________________ geda-user mailing list geda-user@xxxxxxxxxxxxxx http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
