TSW14J56EVM: HSDC pro time domain raw data acquisition problem

Part Number: TSW14J56EVM
Other Parts Discussed in Thread: ADC34J45EVM

Hi,  

    I am currently working on ADC34J45EVM and TSW14J56.  

    I meet a problem about the get time domain raw data from HSDC pro. I found there are some Automation DLL program inside "HSDCPro automation DLL " folder. But the raw data can only be stored in CSV or Bin files. I am desired to get the raw data directly in LabVIEW and then I need to do some data processing for the raw data in real time.  Right now I have to save data in CSV file and then read this file from LabVIEW every time. It is so time-consuming. 

   So do you have any alternative solutions for the problem.

 

   Thanks, best regards

    Yue,

    The automation control for Labview, Matlab and C were created to allow some automation for bench characterization sweeps.  It was never intended for prototyping or real time applications.  The speed with which it does this is as fast as the HSDC Pro GUI since the commands are for controlling the GUI.

    Let me see if there are any alternatives other than to build custom firmware and do your processing in the FPGA.

    Yue,

    If you use bin file it may be a bit faster, but not by much. You will need to remember to close the bin file prior to making another capture.

    We do not support any other faster method of automation - the fastest and realtime method will be to make custom firmware and modify the data in the FPGA. The TSW14J56 firmware project source is available on the ti.com site.

    Thanks, Ken 

            So right now the automation only can read the raw data from DDR and store in bin or CSV file, unless I need to modify the source code of firmware, right?

    Yue,

    The automation functions actually control HSDC Pro as if you were clicking buttons on the GUI. There is no direct control of the hardware from the automation dll. As such the automation can only do what HSDC Pro can do, in this case it can either save the data as bin or CSV. Normally it would transfer the data from the capture card, then perform analysis on the PC.

    I got it.
    And is it possible that I can get a LabVIEW source code of the HSDC pro?

    Thanks,

    Yue
