Display MoreDear 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 pins from the frame grabber? If it is the latter, I have attached a small VA example on how to access these.
Please let me know what do you need in detail.
Greetings,
Kevin
Dear Kevin,
may I ask
- where is the parallelism error from? (I assume both the operator "Less" and "PixeltoVal" should be single I/O)
- Also, is the operator "CoordinateY" only read the pixel value of Y ordinate and make the pixel values as a stream, so that is kind of line scanning?
Best
