It doesn't sound that hard, but without more information, no one can just put together code for you. It depends how you're feeding the information to the "hardware," whether via an analog out port on a DAQ board, or serial communication, or whatever. As someone else mentioned, if you need it really quickly, you have to either call someone else in to do it, or be prepared to put in some long nights doing a Labview crash course. If you have specific questions, people can help, but general requests for solutions with little else won't net you much, unfortunantely.
My only advice is to not be daunted by the large VI palettes. Just open up some sample code for, say, file I/O, and try to understand it. Have the manuals out in front of you and look up VI definitions yo
u don't understand. And just go for it - the best way to learn Labview is to jump in and do it. Your program sounds like a day or two's full coding at most, so you can burn some time learning and not just writing the final product. Again, if you have specific questions (what's the difference between a cluster and, say, an array) people will be more likely to answer those.
