Revision history [back]

Good morning

Thanks for the clarification. I did get it to work... sort of. I first got this:

[DEBUG] rqt_plot.plot: import of PyQtGraphDataPlot failed (trying other backends)

Then the plotter came up and displayed my data (way cool) But I'm curious about that initial error. What does this tell me?

BTW instead of using the IR sensor spec'd in the tutorial, I'm using an SF02 from Lightware rotating on my "open source" platform found at http://diydrones.com/group/ardurover-user-group/forum/topics/contributing-to-giving-sight-to-av-s

Thanks

RoboBill
