TSW1400EVM: External Trigger function.

Part Number: TSW1400EVM


Hello, I have the following problem I am trying to create an environment of study in the university to be able to acquire signals and later to be able to work with the obtained results. For this, I found it very interesting to use the AFE5808 and TSW400 cards from Texas, which as I can see, allow me to work easily with students through the use of LabVIEW. However, I found a problem that I did not have, the Trigger control. When I read the specifications of the TSW1400 card I noticed that I had an external Trigger, with which I thought I could launch the capture at the time I wanted, and I can effectively do it with the HSDC Pro program without any problem, but I just wanted to have the .dll libraries provided by Texas, without having to start the program every time. In this post I found the possibility of using the TSW1400Board_CLib.dll library that does not need to have previously released HSDC Pro, and I can create a simple LabVIEW program that acquires the signals, but nevertheless, I can not find the function that allows me to control the Trigger . I am only able to acquire signals continuously, but not at the time I request it. The only function that seems to allow controlling the Trigger is TSW1400BrdCtrl_Start_ADC_to_DDR, but I do not understand how it is used. My question is: Is it possible with this or another library to be able to control the trigger, without having to use HSDC Pro? I hope your answer. A greeting.

  • Hi Mariano,
    How are you?
    Thank you for using AFE5808EVM and TSW1400EVM.
    For your concern about the TSW1400 board external Trigger signal pins,
    please refer to one example (in AFE5818EVM User Guide page 35,36, "Triggering Options" this page):
    www.ti.com/.../AFE5818EVM
    then you can understand how it works more clearly.

    Thank you!

    Best regards,
    Chen
