TDC1000-C2000EVM LabView help

Other Parts Discussed in Thread: TDC1000

Posting because I was recommended to post here instead of the ultrasonic sensing forums. I am having issues interfacing with the TDC1000-C2000EVM using LabView. I want to take data out into LabView and manipulate the data for level sensing purposes. Surely there is a way to do this besides exporting and loading data, but I can't figure it out. Any help would be great.

    Hi Ed,

    I am not familiar with this kit, so bear with me for a couple basic questions:
    -It looks like the kit GUI is developed in LabVIEW. Is this distributed as an executable (using LabVIEW runtime) or is the source LabVIEW distributed?
    --->If executable, it seems like you would want the source LabVIEW for the GUI (this should have whatever libraries are used to communicate with the c2000 device)?
    -Does the GUI communicate with the kit while running? If so, does it use JTAG, or some other method (like a virtual serial port over USB)?

    This kit comes with its own executable that interfaces directly with the LabVIEW VISA interface. I tried to look into the deeper portion of the code to see like the block diagram or whatnot, but it is locked. I tried to look into the source code for the executable, but I am not that adept at translating the C code into writing the interface for VISA in the LabVIEW interface.
    The GUI does interface with the kit while it is running. I am able to, in realtime look at the time of flight values read from the TDC1000 as well as the graph over time. I believe the connection that it uses is UART for communication with the computer.

    Browsing the forums, I saw that TI employee gave out LabView source code for a similar product, would it be possible to get the LabView source to make things much easier?
    Thanks in advance

    Hi Ed,

    I am looking into this. It may take a couple days.
