Tom, Steven

One of the most common interfaces with LabView software a GPIB interface which is a standard for many kinds of electronic instruments. It can also talk over other links like RS232 and USB if you have the right LabView drivers.

Tom,
Thanks for the quick reply. I know C, but for embedded processors. Which is why I like LabVIEW; it's easier for me to make user interfaces in labVIEW. My recent user interface experience in C is usually through buttons, LEDs, serial ports, and LCD displays :-)

I know that LabVIEW can interface to DLLs, but that's something I've never done. I was hoping to find someone who's done it before to offer some hints. I think I can find someone who can help me on the LabVIEW end of things; I assume there is a .DLL that is installed when I install the KMotion software? Is it obvious (to someone who knows what they are talking about) what it's name is, and where it's located?

As for the serial port option; I understand serial ports well. I've talked to things with FTDI chips via LabVIEW; they have always showed up as a standard serial port. Is there a summary of the serial commands somewhere?

This has been enough encouragement for me to install the latest software today and see what I can make it do.

Thanks again!
