Painter,
I certainly don't claim to be an expert at using the DataViewer, there is a parameter named "E_LED_ATTI" that could equate to "Error LED Attitude" if you've had enough to drink.
That parameter seems to be a binary on/off value, that on my system very rarely triggers.
An autonomous mission I flew yesterday where the FLY???.DAT file shows 700 seconds of which only about 200 of those are actually flying. The first 500 seconds are the time in the file after I plugged in the battery to start the file and get the PC Ground Station photogrammetry mission defined and uploaded.
When I look at the FLY.DAT file, the "E_LED_ATTI" signal triggered twice during that 700 seconds for about 2 seconds each time.
The first time was a few seconds after I plugged in the battery, but well before I took off. If the "E_LED_ATTI" signal is attitude error, it could be that I bumped the UAV fiddling with the camera or something and pegged the gyros enough to transcend some secret attitude threshold.
As I say it was momentary and went away after about 2 seconds.
The second time that signal triggered was, as near as I can tell, during one of the turns on the photogrammetry grid.
The reason I think this parameter might be an attitude threshold is that there were a total of 8 turns on the autonomous flight, and the second "E_LED_ATTI" trigger corresponds to what looks like 2 seconds into the sharpest turn on the flight looking at the changing longitude.
