20230426 Dev Meeting

General:

• Update from relevant previous calls
• Tagged: issues, PR.

Notes

• 6pm new meeting time.

• RFC16: Standard Modes: Metadata support/overrides and dynamic modes #23

  • Argument for:
    • Standard mode definitions very broad because they have to cover existing implementations.
    • They are considered sufficient for an unknown GCS to be able to provide adequate support.
    • This allows an autopilot to provide better information about the particular implementation (within the broad scope of the standard mode).
    • This allows alternative implementations of standard modes to be provided at runtime (only one at a time).
    • Also happens to allow custom modes to be supported at runtime, and to have metadata.
  • Concerns that it makes a simple concept more complicated. This might discourage adoption, or misuse.
  • No particular concerns with the implementation (so far)
  • Agree worth taking to our communities to discuss - AO JamesP/Beat.

• Low Latency MAVLink Messages for VTOL

  • They are no longer suggesting own message set but want help.
  • AO to HamishW to suggest starter message set.

• common - un-WIP gimbal messages #1973 - WIP on device

  • Julian thinks we should unwip the manager messages based on:
    • They are deployed
    • initial look at GCS implementation indicates they are suitable
  • The GCS implementation DavidSu. looks like it is heading in right direction, but is not sufficiently compatible yet. David and Julian continuing work.
  • AO HamishW to add PR to re-wip the manager cases. But not necessarily merge until GCS stuff has progress.

• component metadata: add translation docs #498

  • Merge

• mavlink_msg_xxx_decode by mavgen_c does not handle extensions of message properly #684 - pymavlink bug fix

  • AO JamesP to see if we can get review from PeterB

• message_definitions: add all_with_development.xml #1924

  • Aim is to stop WIP being compiled to releases of tools by accident, making it defacto frozen.
  • Suggestion is to warn by default when a WIP command is built into a library, but allow this to be disabled via a flag.
  • This is still blocked.
  • JamesP seeking more suggestions.

• New cmakelists #1977

  • Can't set to use allxml by default as this includes development.xml, and we don't want to suggest that until ^^^ is fixed.
  • No choice but to set common.
  • AO JulianO to take first stab at docs.
  • Should be good to go following reviews, but would like documentation first

• Added "shortest way" as an option for yaw direction in MAV_CONDITION_YAW #1962

  • FYI is pending implementation by AndKe.

Attendees: Hamish, JamesP, JulianO, BeatK, JonasV.
