AFE5807EVM: two TSW1250EVM board synchronization and data continuous saving to PC under external trigger

Part Number: AFE5807EVM

Hi,

          Currently, I use an AFE5807EVM+TSW1250EVM to test the ADC capture data from ultrasound input. I have a question about synchronization. For example,  I want to use 16 channels ultrasound input, that is I need to use two AFE5807EVM+TSW1250EVM, I know I can input a trigger to two TSW1250EVM's external trigger port get them synchronized. But there is an issue about save data to PC from TSW1250EVM. Currently, when I use the software TI supplied, I need to click one button to save once under the external trigger mode. This is definitely not my need. I need to keep saving when the trigger comes. I'd better have the Labview source code instead of just executed software to know the command the PC gave to FPGA. Do we have the source code or is there some solutions? Thanks!

    Thank you Chen, I think AFE5807EVM+ TSW1405EVM no problem, just the FPGA software on the website is not updated, and can not find the AFE5807EVM. Thank you!

    Hi Guang,

    How are you?

    Here is a new AFE5807_12x.ini file stored

    to the attached file.

    After you save this attached .ini file, please copy this file under your PC's directory

    (used for AFE5807 device working with TSW1405 EVM data capture card purpose):

    Please note: This .ini file only works for the following register modes:

    MSB first mode, 12x bit mode, Offset Binary mode

    C:\Program Files (x86)\Texas Instruments\High Speed Data Converter Pro\1405 Details\ADC files

    AFE5807_12x.ini

    Then please try it.

    If any question, please let me know.

    Thank you for using AFE5807EVM and TSW1405 EVM.

    Best regards,

    Chen

    Hi Chen,
    I have done as you said. However, it looks like the FPGA board did not work. Before I connect the AFE5807EVM to TSW1250EVM, and the input signal is 2 MHz sin wave. I can get a SNR around 70dB which agrees with the AFE5807 datasheet.
    However, I use AFE5807EVM+ TSW1405EVM and still input 2MHz sin wave. I almost can not find the signal in the single tone FFT mode. I am not sure whether the FPGA did not work or the drive you send to me is not right. I have set AFE5807EVM to MSB first mode, 12x bit mode, Offset Binary mode. Very weird....

    Hi Guang,
    How are you?
    How about please try the following setting on your AFE5807 GUI as:
    Please set AFE5807 GUI: 12x, Offset Binary, LSB_First

    Hope this time it may help!
    Thank you for let us know!

    Best regards,
    Chen

    Hi Guang,
    Thank you for letting us know it works!
    Have a nice day!

    Hi Chen,

            I have another question about the TSW1405 EVM. I just checked its circuit schematic. I am curious that in the USB part, we use this chip called FT2232H. why we use 4 USB output from ADBUS0-3 and another 4 USB output from CDBUS0-3? Why half from one USB and a half from another USB (This chip has two USBs)? Thank you!

    Best,

    Guang

    Hi Chen,
    Another urgent question. if I bought 2 sets of AFE5807EVM+TSW1405EVM and want to use the High speed Data converter pro software to capture simutaneoulsy, can I open 2 softwares simutaneously in one computer??if not, do I have another solution? Thanks
