UTC0725 - DroneCAN: removed the old GPS Fix message by tridge · Pull Request #21813 · ArduPilot/ardupilot · GitHub

  • Get rid of old GPS fix messages
  • Does mean very old devices may not work

UTC0734 - Implement MISSION_CHECKSUM by peterbarker · Pull Request #20834 · ArduPilot/ardupilot · GitHub

  • Implement mission checksum
  • Not convinced how useful this is
  • If we merged would not want to run on smaller boards
  • Concern that this is an alternative to mavftp
  • Tridge not totally convinced
  • Still pending in QGC
  • We really should push back on this - will create a support nightmare and not achieve the intended goal

UTC0803 - Add support for DShot in IOFirmware by bugobliterator · Pull Request #21569 · ArduPilot/ardupilot · GitHub

  • Dshot on IOFirmware
  • Creates two iofirmwares in the image for an extra 25k
  • Nice in that you can use the 5v level shifer
  • Some concern that the prescaler algorithm has been changed and might yield different results
  • Need some warning about incorrect setups.
  • Some discussion about having different firmware to incorporate this or merging into bdshot
  • Needs some flight testing
  • Needs testing on oneshot and brushed output
  • Bdshot not possible because of level shifters
  • Sid still needs to implement dshot telemetry
  • Adds threads to iomcu - needed to hit 1Khz output rate
  • Lose some rc protocols
