How do I get the data from TSW14J56EVM directly without GUI?

Other Parts Discussed in Thread: ADC12J4000EVM

Hello,

I'm using TSW14J56EVM for capturing data from the ADC12J4000EVM board, and intending to analyze data with MATLAB directly.

In order to do additional functions at the same time, I need to get the raw data instead of FFT data.

Do you have any idea that how to do that? I believe I have to deal with the dll file which is TSW1400Board_CLib_1.0.dll, and, if this is he case, I might need the header file of it to use it in MATLAB.

Thanks

    Hi,

    Please go to this directory on your PC for examples on how to automate/control HSDC Pro to collect data within Matlab or Labview.  This will show you how to use the DLL to do what you need.

    C:\Program Files (x86)\Texas Instruments\High Speed Data Converter Pro\HSDCPro Automation DLL\Manual and Examples

    If you just want the captured data you can just save the raw data in FIle menu.  Either save I32 codes as CSV file, or Save Raw codes as Binary file.  Then load these into Matlab.

    Thank you Ken.

    I know I can save raw data by the GUI, but what I need is adjusting the data right after getting it.
    Is there any way to get the raw data without using the GUI?

    Hi MHC

    As Ken stated earlier, there are Matlab automation examples in the High Speed Data Converter folder here:

    C:\Program Files (x86)\Texas Instruments\High Speed Data Converter Pro\HSDCPro Automation DLL\Manual and Examples\Automation DLL Matlab Example\64Bit Matlab

    and here:

    C:\Program Files (x86)\Texas Instruments\High Speed Data Converter Pro\HSDCPro Automation DLL\Manual and Examples\Automation DLL Matlab Example\32Bit Matlab

    An ADC example and header file are provided. The Automation DLL manual is in the location Ken provided earlier. The HSDC Pro GUI needs to be running, but the control is from the Matlab script.

    Best regards,

    Jim B

    There is not an easy way to get the data without using the HSDC Pro GUI. This would require a dedicated DLL to the TSW14J56EVM and we do not support this type of DLL at this time.

    We are only able to support a generic HSDC Pro DLL which allows us to control the other versions of capture cards via the HSDC Pro GUI (TSW1400, TSW14J56, ...)

    Ken.
