Mateksys has offered to send a developer or two an F765 based flight controller. Any volunteers to do the port?


(Craig Elder) #2

Attendee count (max): 20

Pre-agenda:

  • New version of ChibiOS has been in master for a while

    • Should consider moving to it on stable?

UTC2300 - battery parameter conversion broken on 3.6

  • https://github.com/ArduPilot/ardupilot/pull/9700

  • Removes some older parameter conversion code

    • Only people upgrading from something built in 2013 will be affected
  • For those that have installed current Plane stable

    • If they’ve fixed it in Plane then the fix will stick
  • Could be bad in Copter as it does have defaults for the battery failsafe stuff

  • This is an important fix for Copter and Plane

  • Randy will test this

UTC2305 - https://github.com/ArduPilot/ardupilot/pull/9690

  • Sometimes doing the sqrt and checking for NAN is actually a fast way of doing things

  • Need to make sure we’re not doing isnan checks afterwards

  • MdB quickly found a problem where blindly changing to safe_sqrt was the wrong fix

    • He will provide a patch

    • Not a good place to use safe_sqrt

  • Base it on floating point exceptions enabled in SITL?

  • We already die in SITL unless no-fpe is set, and you might want to replicate what will happen on stm32 - and this PR would stop that happening

UTC2305 - https://github.com/ArduPilot/ardupilot/pull/9690

  • Minimal fix

  • Doing this on the IO thread would be better

  • Merged!

UTC2310 - https://github.com/ArduPilot/ardupilot/pull/9661

  • ChibiOS IO processor firmware

  • As part of the continuing efforts to get rid of the PX4/NuttX submodules

  • Adds IO failsafe

  • Adds DSM support

  • DSM binding

  • Marge set of patches

  • Please test this!

  • Fixes a race condition

    • Intermittent Safety switch on boot issue

    • Fixes BRD_SAFETYENABLE intermittency

  • Hopefully 3 weeks to remove NuttX/PX4 Firmware submodules

  • Appeal for testing will go out

  • MdB will test after the call

    • Manual mask and safety mask

UTC2319 - https://github.com/ArduPilot/ardupilot/pull/9391

  • No update, tridge has been busy!

  • Along with lots of other devcall-marked issues

  • And one for Leonard

UTC2320 - https://github.com/ArduPilot/ardupilot/pull/8839

  • Needs to zero the structure

  • Check the return value of set_home and don’t lock a bad position in!

UTC2334 - changed the VFR_HUD message

  • Altitude in MinimOSD relative to Sea level ?!

  • Should we switch back?

  • Should we add a parameter so people can change it?

  • Minimosd

    • Only a couple of versions we care about
  • HOTT and graupner

  • JP: we need to get it right at our end

  • Use devop bit to get back old behaviour

  • For people that can’t update their minimosd firmware

  • https://github.com/mavlink/qgroundcontrol/pull/6986

  • Would like to use minimosd as a screen update protocol rather than mavlink

    • Use existing ArduPilot OSD code

    • Would also future-proof things

  • Mavlink screen-painting message?

  • Peter will add a devop bit to get back old behaviour

    • Add comment on discuss post
  • Need to work on getting testers before we issue stable

  • Working with consumers of our telemetry stream

  • Users don’t update?
