Dashboard Robot SDRead Communication Problems

[Greg McKaskle]

Just to clarify a few things. The SD and NT functions work almost identically except that the SD functions automatically add "SmartDashboart/" to the variable name in order to keep it separate from the other types of Network Table variables. The storage, transmission approach and other aspects are the same.

I believe the size limit of strings is actually pretty small. It is implementation dependent, but cannot be larger than 65k characters. So in some implementations you may be able to store an image, but that may not work consistently.

I'm not sure I have enough info to give a suggestion on how to setup your camera, but the camera supports both JPG read of a single image and an MJPG session which sends images without asking for each. If using MJPG, you need to read them as fast as they are sent or they will lag behind. You can ask the camera for a very low framerate. Because it was not often needed and caused confusion, I believe the JPG option is in vi.lib, but not in the palettes. If you want to use it, it is in the same folder as the other camera VIs.
