  1. OpenCV has very good support for various camera standards.
  2. Try configuring the DMM to use a single range. If there is an auto range function active, it might explain the waveform. Can you post the circuit?
  3. It doesn't exist in LV2015.
  4. Of course someone can. General questions get general answers. Can you provide more details? NI has the LabVIEW core 1 course available.
  5. I'll give it a shot later today. Might require Wireshark.
  6. You can reverse engineer the protocol with NI-trace. It is quite trivial.
  7. You know that these glyphs are in the C:\users\<username>\Labview Data\Glyphs folder as .png files, right?
  8. Take into account that MXI has its own set of limitations. You cannot hot-plug an MXI connection reliably, It is a single source (NI only, AFAIK).
  9. You might want to consider MXI (Either optical or copper) as an alternative. It avoids another layer of drivers. Desktop PCs with Thunderbolt exist, (Mac pro, other high end workstations from Dell or HP).
  10. What is the difference between these two methods? If a .NET library is included in a project, does LV load it before the VI is run?
  11. You should check that both the DLL and LV have the same bitness, 32 bits or 64 bits, not mixed. You might be able to bypass the entire problem, if you can create a raw printer file. 1. Create a raw file - usually label printers use a text based encoding (for example, Zebra printers use ZPL, other vendors have similar formats). This will be your template file. 2. If you are using Windows, create a printer share. 3. Set the fields in the template. 4. copy the file to the share - using the system call, issue a copy <filename> \\localhost\<share name> command.
  12. What are you trying to do, print something? Can you post a link to this driver?
  13. I am using EmguCV. You need to convert the mat into a bitmap, and if you are using the .NET PictureBox control, you have to create a graphics object, then use the ToBitmap method of the MAT to draw it.
  14. Do you get a response to IDN query via MAX VISA Test panel? If not, check your hardware. For the VISA write, make sure your string is set to '\' Codes display, and add a \n - line feed, not a literal \n.
  15. Type object is in the System namespace. Click .NET connectivity -> Invoke node -> Select class -> System -> Type -> Missing
