    VisualApplets can be used to transfer serial data over the IOs of the frame grabber. Application areas are for example
    • Control eject mechanism like valves for bulk material sorting.
    • Object x- and y- position output. For example for laser welding and

    Dear Oliver,

    Please find attached a small example extension for the VF2 trigger example: In this example the R,G, B lines sent from camera (as described in the camera manual) are resorted to R,G,B pixels. The example is useful when the spatial…

    Dear CarmenZ,

    Many thanks again for the new idea. I'll implement it.

    Dear Jsmvub,

    please consider the following suggestion :

    Ln(A/B)= Ln(A)- Ln(B);
    So you can seperate the problem.

    In a Const operator you directly can write the value Ln(A) and for the image data B you can use a LUT .

    Dear CarmenZ,

    Thanks for the idea. The LUT could help me, but not entirely.

    My use case is, I need to do the following calculation:

    Ln(A/B)
    • A and B can take the values from 1 to 255.
    • A is a dynamic CONST
    • B is my image
    One solution I have in mind is…

    Dear jsmvub,

    yes the Ln(x) function is not directly implemented as VisualApplets operator. But you may use a LUT operator to implement this function.

    Hello,

    For my current application I need to make use of the natural logarithm function, Ln(x).

    I've seen that Visual Applets does not offer this function in its arithmetic library.

    I'd like to ask if there is any support available, or the natural logarithm…

    Hi Oliver,

    I did an applet for this camera long ago (I think it was like 2 years ago). I still remember the problems I had building it.
    First of, you need to do the sorting of packages into an image yourself. The camera sends the lines in packages with…

    Dear IhShin,
    thank you for your answer. The licensing model of VisualApplets has changed from VisualApplets Version 2 to 3. Please contact your local sales contact for an update of the Dongle license.

    Dear CarmenZ,

    VisualApplets license features currently in use include VA Core and VA Gui. The protection option is active in VisualApplets 2.1.1 version, but not in VisualApplets 3.3.0 version.

    thanks.

    Dear IhShin,

    thank you for your question. May I ask which VisualApplets license you have? The described problem is most likely due to a VisualApplets license, which does not support the protection feature. If you want to update your VisualApplets…

    Hello,


    I tried to protect the user library element by referring to the link below, but I don't see the Protection option.

    Dear Bingnan,

    Thank you for reaching out. The ImageTrigger Box is for accessing the camera, my question is what do you exactly mean by a trigger signal. Do you want to trigger the Camera again if you detect the circle, or do you want to acces the GPIO…

    Dear Pier,

    Sorry for the late reply. You can see an example for the usage of the fft operator in the example under:

    Sadly, the fft operator only performs a one dimensional fft as you mentioned before.
