  • Remove channel parameters
  • Tridge uses intermittent for taildragger and reset
  • MdB’s override thing has been left in place
  • Parameter conversion is a thing
    • Checks configured()
  • Flap, soar enable and fence all done
  • Some savings to be made byte-wise
  • Mount has a bunch of equivalents

UTC2352 - https://github.com/ArduPilot/ardupilot/pull/16875

  • More than 6 modes
  • Want to have mode-switch-layout-schemas
  • Want to hide the extra flightmode parameters if we can
  • Stavros wants more than 6 channels
  • Quadplanes want more than 6
    • Even some planes
  • Modern OpenTX transmitters have 2 3-pos switches that can be used for mode
  • Two separate channels?
    • Lots of channels on modern transmitters
    • Like a “bank select”?
    • Mixer on transmitter is major barrier to entry for ArduPilot?
      • Transmitter setup is too fragile
    • Three groups of three flight modes for example
    • 6-deep-each banks?
    • Default has to be our existing scheme
  • The FLTMODE parameters should be common between vehicles
  • A new AP_FlightMode library?
    • Rover is AP_Mode
  • Use MODE_xyzzy
  • Fix the documentation issue so we don’t duplicate everything
  • AP_FlightMode would contain logic for selecting modes
  • AP_RCModeChannel?
  • Won’t merge this or close it

UTC0022 - https://github.com/ArduPilot/ardupilot/pull/16869

  • New FlyWoo board

  • Quadspi support - external flash
    • 4 or 8MB of external flash…
    • Several flight controllers coming out with this
    • Betaflight are already using it
    • 1 sector of built-in flash and then external flash
    • Three can buses
    • Redundancy
    • CAN Bus ordering
  • Need to scrounge up some bytes in the bootloader
