Using LabView to operate RMV's Sport232 Stepper Motor Controller

[Rand]

I've encountered quite a headache attempting to use LabView to control RMV's Sport232 stepper motor controller card, mostly due to my inexperience in working with dlls and how LabView handles the libraries.  I'm attempting to write a .vi that will allow for control of the motor that drives a monochromitor to select visible wavelengths for photospectrosopy measurements.  The controller  program supplied by RMV is inadequate for my application, as the wavelength must be recorded at certain intervals to generate the desired data.  Has anyone had any experience or can anyone offer any suggestions of what I need to do in order to integrate the Sport232 dlls with LabView?

Thank you in advance.

Hi Rand!

I unfortunately I have not worked with your particular board, but I have included links to another discussion forum and a tutorial on how to call external dlls in LabVIEW.  If you haven't already, please read through these and see if you can get your dlls to work in LabVIEW.  Also, you may want to contact the board manufacturer and see if they have a driver for your version of LabVIEW.  If so, it may install palettes and functions that already call the dll(s) for you.  If the driver is not available, please refer to these links for step by step instructions on how to call dlls:

Best of luck to you and let us know if you have any additional questions!  Have a great day!
