UTC0006 - AP_Motors: merge the three Sub's output functions by Williangalvani · Pull Request #34182 · ArduPilot/ardupilot · GitHub

  • Merge the three sub output functions

  • Willian will merge it when he’s happy

UTC0009 - https://github.com/ArduPilot/ardupilot/pull/34234

  • Report the full navigation setpoint to theGCS

  • So you get velocity and acceleration now

  • What goes in there?

    • Position controller?

    • Flight mode?

    • This is usually used as a “where am I eventually going?” vs “current position target”

  • Does this partner with set-position-target-global-int

    • Leonard’s interpretation: “This is where the aircraft wants to go if left to its devices”

  • We’ve used this for the waypoint destinations

    • Can we change it?

  • Probably useful for tracking stuff

  • merged!

UTC0058 - Tools: accept the subsystem prefixes the project already uses by andyp1per · Pull Request #34442 · ArduPilot/ardupilot · GitHub

  • Enforce @READONLY defaults over stale values

  • Could this affect calibrations?

  • We should probably have @FORCEDEFAULT rather than @READONLY

    • So we don’t screw over existing vehicles

  • Some users might be using @READONLY on calibration values, in which case this would give them a very bad day

  • @READONLY_FORCEDEFAULT?

  • Review left
