An arbitrary waveform generator using the DSP Module

[Ben_S]

GibbGodD,

Hello! I did confirm that you can use VB.NET to interface with a LabVIEW Front Panel that is running and according to this document, "the power of LabVIEW DSP lies in the fact that you can interact with the program running on the DSP in real time and see the results on your front panel." That being said, you should be able to access a DSP front panel the same as a LabVIEW front panel.

To answer your second question. Yes, LabVIEW has many File I/O VIs and functions that can be used to read and write from a variety of file types. Check out this article that Compares Common File I/O and Data Storage Approaches. Also, check out the two examples below on File I/O or go to Help >> Find Examples >> Fundamentals >> File Input and Output from within LabVIEW for a multitude of additional File I/O examples.

• File I/O - Basic
• Read a Text File From an Offset Position

Once you've stored your waveform in a file and are able to read that data back into LabVIEW you can use the Build Waveform Function to turn that data into a Waveform, however, that shouldn't be necessary. If you read your file into labview and turn it into an array, you can simply output the array data by indexing the value each time you want to update your signal.
