PX4 v1.6.2 requires a recent version of QGroundControl for the best user experience, currently available as “daily build” here.

New Hardware Support

  • Crazyflie v2
  • FMUv4 PRO (Prototype donation and manufacturing: Drotek)
  • FMUv5 (Prototype donation and manufacturing: Team Blacksheep)

New Features

  • New .ulg uLog logging format which directly logs uORB topics and offers more accurate time stamping. Supported in FlightPlot. @bkueng
  • New web-graphing engine for .ulg: http://review.px4.io @bkueng
  • Easier to use camera triggering @mhkabir
  • Basic support for real-time camera triggering feedback @mhkabir
  • Support for survey flights (multicopter and fixed wing) with intuitive UI
  • Temperature calibration and compensation (gyro, accel, mag, baro)
  • Support for MAVLink and PWM controlled gimbals @bkueng
  • Support for generic helicopters and Blade 130 mixer @bartslinger
  • Fixedwing acro and rattitude flight modes

Major Upgrades

Bugfixes and Improvements

  • More reliable reboot of Pixracer boards
  • Log tasks low on stack @AndreasAntener
  • Prevent overshooting of landing waypoints on VTOLS by calculating the acceptance radius based on ground speed @sanderux

  • Temperature calibration for IMU and barometric sensors @bugobliterator @priseborough
  • Don’t allow arming in low battery condition @LorenzMeier
  • Enable takeoff and landing with just local position (e.g. flow) @ChristophTobler
  • Add fixed-wing acro mode @AndreasAntener
  • Trigger quadchute on maximum roll and pitch angles to prevent stalling or actuation problems like reversed ailerons/elevons @sanderux
  • Add fast EKF2 replay for new ulog format @bkueng
  • UAVCAN performance audit @pavel-kirienko
  • Add preflight, postflight perf counters and process usage to ULog @bkueng

  • Fixedwing throttle scaling with battery voltage @sander
  • VTOL land improved back transition waypoint accuracy
  • TECS height rate feed forward fixed
  • Fixedwing loiter to altitude landing improved predictibility @natorgator
  • Fixedwing limits fix : The FW_PSP_OFF parameter no longer breaches the pitch min/max limits. @sanderux
  • Improved the mixer clipping performance on yaw saturation @bresch
  • BMI055 driver fixes for device IDs (from 1.6.0)
  • Fixes for mag rotation (from 1.6.0 and 1.6.1) @mhkabir
