Spectrum Analyser enhancement for Blackbox Viewer.

  1. The spectrum is based upon 2048 samples from the left hand side of the window (not the center point); zoom level is irrelevant.
  2. Only the first graph field shown at the top of the legend is analysed; change the top graph field to analyse different fields.
  3. The base sample frequency is set to 2000Hz (representing a loop time of 500 in cleanflight/betaflight). Other loop times or logging intervals will work, but the x-scale displayed below the analyser will probably be wrong; It is currently a hardcoded setting; in future this will be adjustable from the GUI.
  4. There are some subtle graphic enhancements:-
    • There is a background showing the graph extents (to make it easier to spot the full range of the graph values)
    • The graph center line is now dashed to distinguish it from a graph pen.
    • There is a new graph setup selection for rcCommand to make it easier to select when setting up your workspace.
