UTC1106 -

  • Two almost identical templates, one now being removed
  • merged!

UTC1109 -

  • Prevent land failsafe going back to do-land-start
  • Whitespace fixes?
  • Can be merged after whitespace fixes

UTC1112 -

  • Add param set/get
  • Great capability
  • Find call looks scary
    • [10:13 AM] To Weekly devcall: Maybe need to keep a “handle” on a parameter?
  • Holding semaphores in scripts is scary stuff
  • Any scary stuff in terms of race conditions when we register stuff e.g. quadplane?
    • Probably not ATM
  • merged!

UTC1117 -

  • Compass ordering improvements
  • Randy tested it and couldn’t find any bugs in flight code
    • Also tested the MissionPlanner screen and found plenty of issues
      • MO is chasing
  • Interesting type-safety trick
    • More comments would be nice
    • And some variable naming
    • But this is something we can use in other places
  • External interface to compass library isn’t changed all that much
    • 1st/2nd compass you just ask for it
    • Behind the scenes it uses a priority scheme to return an object
      • Could get interesting from a logging perspective
        • Only in parameters, not in log messages
  • Reboot required for parameters to have effect
    • Need to be tagged @RebootRequired
  • On boot parameters are reordered
  • Casting needs to be fixed
  • Should be merged mid-week

UTC1126 -

  • This probably won’t play well with dynamically inserted SD cards
  • Could possible create the directory when an SD card is inserted
  • Having a SIM parameter which disables file system access would be good
    • So you can start simulation without storage available, fail to arm
  • Closed as breaks dynamic insertion

UTC1131 -

  • Don’t recalculate stuff when not required
  • Merged!

UTC1134 -

UTC1135 -

  • Reduce memory usage associated with sandboxing
  • 8500 less bytes ram for trivial scripts
  • And makes CubeBlack smaller
  • Don’t embed romfs file
  • Hacking lua sourcecode to remove stuff
    • When hacking - comment or #ifndef?
      • Less likely to conflict
    • Will move to next version of lua and do this a bit better

  • merged!

UTC1137 -

  • Merged

UTC1139 -

  • Allow scripts to do prearm checks
  • One string for failing external authoriser
    • Only first failing authoriser gets to whinge
      • Like GPS library
    • High memory cost for doing all authorisers
  • [10:42 AM] (Channel) MdB: bitsets do 32 for free :smiley: this is why I’m so keen on it :smiley:
  • MdB wants to have a closer look
  • Tridge wants string-per-one
  • Arming check for allocation-has-failed?

  • MdB will merge after he’s looked at it

  • Equals-stdin on load-buffer?

      • Copter and Sub
      • Plane and Rover and Tracker
  • Parameter conversion code would get a touch complex
