UTC1106 - Allow flashing autopilot from file-on-SD-card by peterbarker · Pull Request #21474 · ArduPilot/ardupilot · GitHub

  • Allow flashing from SD card
  • Works on 6x and CubeOrange
  • Can be merged so long as the min firmware isn’t being significantly modified

UTC1115 - Add support for JUMP_TAG mission items by magicrub · Pull Request #22421 · ArduPilot/ardupilot · GitHub

  • Support for JUMP_TAG
  • Make it easy for a gcs to go to a specific tag
  • Jump with repeat count of zero is annoying
    • Should change mavproxy default to -1 for infinite loop
  • Basic ability to jump to things
  • Jump to waypoint landing 1, waypoint landing 2
  • Why re-use jump rather than implement as command type?
    • When you download you get jumps
    • But they’re instantly resolved
  • The API on the next PR in this sequence needs work
    • Tridge wants the tag available all the time
      • To mark sections of the mission
      • “What was the last tag, how many waypoints have been crossed since then?”
    • Integer number of spaces away from jump tag rather than boolean
  • Need to remove from ROMFS!
  • Mission resume could also be a problem
  • Active tag is the latest tag you’ve passed?
    • Call it “last tag”

UTC1147 -

  • Quadplane prearm mode checks
  • Need to shorten the prearm failure
  • Can see it with –osd to
  • Just remove “mode not armable” and use that string as the default
  • Shorter strings and then this can go in

UTC1159 - ChibioOS: hwdef: CUAV-X7: correct 6.6v ADC scale factor by IamPete1 · Pull Request #22831 · ArduPilot/ardupilot · GitHub

  • Correct ADC scale factor on CUAV-X7
  • Partner decision as to whether it gets merged
  • This PR could crash a vehicle if people are using an analogue airspeed sensor
  • Could we have a second virtual pin with the correct scale factor?
  • Will ping CUAV on the matter

UTC0005 -

  • Add resting cell voltage and refactor
  • Saves flash and more features!
  • Merged!

UTC0006 - StorageManager: add compile define to favor more mission points by magicrub · Pull Request #22856 · ArduPilot/ardupilot · GitHub

  • Add compile define to favor more mission points
  • Allows for ~1800 waypoints bit loses fences and stuff
  • There’s a region in the storage area which is a backup of parameters on e.g. CubeOrange
    • Use for missions instead?
  • This PR isn’t good
    • We’ll have an option to replace the backup
    • Or from-sd-card
      • Tridge might get this for the conference
  • Infrastructure doesn’t scale
    • Mavftp makes it work
    • MissionPlanner has a tickbox for uploading mission via ftp
    • Atomic, too…
    • Uint16_t index values are a limitation

UTC0020 - Plane: use Guided mode under the hood for tricks on a switch by IamPete1 · Pull Request #22860 · ArduPilot/ardupilot · GitHub

  • Guided mode for tricks-on-a-switch
  • Changes to guided and then switches back
  • post-PR the GCS doesn’t see the mode change
  • The way we currently do things we also lie
    • You know what mode you’re going to be in after you abort?!
  • Tridge wants to be able to do partial overrides in any mode
    • E.g. roll control but no pitch control
    • He doesn’t want to be boxed into just using guided with external controls
    • Ship landing does partial override?!
      • Navigation override
      • While remaining in QRTL
    • Randy is worried about complexity
      • “Stovepipe” analogy!
      • 11:26 AM]rmackay9: it’s all part of reducing complexity and clarifying who is in control…
    • Pete wants all of the functionality available to guided
      • E.g. landing sequencing (QPOS etc)
    • Avoidance in auto
      • Tridge just wants to change the navigation target a little bit
    • “Tweak” existing mode behaviour
