UTC2311 - https://github.com/ArduPilot/ardupilot/pull/16091

  • Moves rudder arming stuff up into RC channel
  • Unrelated bug found in quadplane arming
    • Ignore rudder while taking off?
      • Copter has landing detection which ignores rudder on ground
      • Takeoff and auto-arming?
    • Race condition getting stick back to neutral?
  • Auto-trim looks odd?
    • Should we remove it?

  • Fix continuous calls to arming checks

UTC2336 - https://github.com/ArduPilot/ardupilot/pull/16506

  • WoW weight one wheels switch (WoW can be waiting-on-weather)
  • WoW causes vehicles to consider themselves landed more easily
    • General agreement that being able to use weight-on-wheels as an absolute is a good idea
      • Option into the future
  • Needs testing on a real vehicle
  • merged

UTC2343 - https://github.com/ArduPilot/ardupilot/pull/16515/files

  • Ned to use tnow rather than AP_HAL::millis()
  • Needs a rebase and handling of tnow

UTC0007 - https://github.com/ArduPilot/ardupilot/pull/16535

  • Tested on hardware now
  • frontend/backend split for external ahrs
  • What would a generic NMEA parser look like?
  • Could use vectornav on a Copter now
  • Dozens of manufacturers making very expensive serially-connected IMUs
  • Fibre-optic gyros?
  • Needs review
  • Would be good to be able to degrade performance in SITL to trigger EKF failsafes
  • Tridge is changing m/s errors into innovations to fit our repoirting

UTC0014 - https://github.com/ArduPilot/ardupilot/pull/16676

  • Flush out stuff before rebooting in SITL
  • Merged

UTC0022 - https://github.com/ArduPilot/ardupilot/pull/16787

  • Can be merged once its passed CI

UTC0030 - https://github.com/ArduPilot/ardupilot/pull/16995

  • Built on top of the memsic compass support
  • Random other bits and pieces that are navigator-specific

UTC0030 - https://github.com/ArduPilot/ardupilot/pull/17031

  • Climb-before-turn not quite right
    • Needs to climb quickly
  • Don’t want to asymptote
  • We’re probably subtracting wrong altitude frames

UTC0038 - https://github.com/ArduPilot/ardupilot/pull/17034

  • Stop watchdogging on log erase

UTC0041 - https://github.com/ArduPilot/ardupilot/pull/17050

  • Redefine output distance logic on teraranger
    • Tell difference between dead sensor and out-of-rnage
  • Essentially reverts MdB’s change
  • 13376
  • Merged

UTC0044 - https://github.com/ArduPilot/ardupilot/pull/17052

  • Gets back some DMA memory
  • Lots of LEDs again
  • Master you can only do 30 or 40 and you run out of memory
  • I2c4 and spi6 - restrictions of matrix of what RAM regions you can use
  • I2c4 might be broken ATM
  • PH to check these mappingsto make sure boards aren’t broken

UTC0055 - cygwin packages / 64-bit stuff

  • 32/64-bit windows
  • We need to use 32-bit packages so we get 32-bit binaries
  • Stephen is helping out
