Need to drive C-2 Tactor

[VLau]

Hi,

I'm very new to LabVIEW and a little lost in the coding process (not my type of programming language). I am a grad student and my project mentor and I trying to figure out how to add an additional function to an existing program (from a previous research project).

There is existing code that takes data from an ATI MINI40-E F/T transducer and displays x-axis force on the screen. I need to take this force data and create an amplitude-modulated 250Hz output signal to drive a C-2 Tactor (Engineering Acoustics, Inc.). The input force from 0 to 25N will correspond to the modulation frequency of 5Hz to 25Hz in a step pattern (i.e. 0-5N will correspond with a 5Hz modulation frequency, 6-10N to 10Hz, etc.).

Is there any existing VI's that my mentor and I can use or modify for this? Also, will we be able to use the 250Hz signal over USB?

Thanks,

VLau

VLau,

It sounds like you have your input displaying data, but what hardware do you have to communicate with this C-2 device?

From what you have described, the math seems simple enough (newton input seems equivelant to frequency output), but how you accomplish this will depend on what hadware you are trying to use to communicate with this device.

There are way too many open questions for us to give a concrete answer. As a first step, can we see the code?
