      I have created a sub-vi which un-pack data comnig from an embedded board with 8 channels and puts on its output the results. Now I'd like to implement an addictional feature which regards the filtering of this data through a low and high pass. So I created another sub-vi that integrate these kind of filters with inputs to set their configuration.
      When I use the filtering sub-vi on only one channel all seems to work well, but as soon as I add another one on another channel it doesn't work: the output signals are not filtered; there some changes in their trends but it's a indefinite behavior, not a low/high pass processing. It seems thet the presence of one filtering sub-vi intereferes with the other. I tryed to understand the problem but actually I'm in a dead end.
      Can anyone give me any suggestion or maybe a solution?

      I am trying to use a mixed signal graph to plot a set of digital data (12 lines) and 4 arrays of analog data in XY format.  For the analog data I want each array to be assigned to a different group in the graph, but at runtime they seem to all default to Group 1 (the Pressure graph shown below).  I have been able to change them using the legend or the graph properties for each plot, but cannot find a way to do it programmatically.  Is there a property node that can be used to set this?

      I am making a project in which i will be taking input from raspberry pi then transfroming single input into string of differnet inputs like voltage ,current, frequency. so how can i transform input that i will be taking from single pin of raspberrypi to voltage,current and frequency

      Hi,
      Is there a way to make a type def behave as a Strict Type Def during development (so that cosmetic changes made to the .ctl are propagated), and as a Type Def. at runtime (so that the cosmetics can be still be changed with property nodes)?
      My use case is that the code just needs to colour the controls at runtime, the other property values are decided during development.

      Hi All,
      I have implemented Kalman filter using LabVIEW 2016.
      You can find the codes here: http://kataauralius.com/index_files/Kalman_filter_in_Labview.html.
      Hopefully this is useful for those who struggle with the implementation of Kalman filter in realtime system.
      Best,
