I’m trying to experimentally compare the effectiveness of various pixhawk vibration-absorbing mounts. I’m using vibration motors to simulate drone vibrations in a controlled way (on increments across a specific range of frequencies and amplitudes).
I have the Pixhawk connected via USB to my laptop with Mission Planner on it…the pixhawk also has an SD-card in it. Also important: for this setup I have no other connections to the Pixhawk (GPS, motors, etc.)
After running a trial, I open the SD-card on my laptop, expecting a .ULG log file of the most recent trial. But I don’t see any.
All I could find regarding this in the Pixhawk website is that:
- “By default, [logs] are created after you first arm the vehicle.”
- " Perform a regular flight (i.e. not just a gentle hover) of at least a few minutes and download the dataflash logs"
But how can I create a .ULG dataflash log without having to fully configure my pixhawk into a drone and flying it?
(I’ve attached a quick sketch of the setup I’m using, in case that helps)
