1.12

Raffaele Rossi

Release 1.12

Pre Releases

Changes

Common

  • RTL Trigger based on remaining flight range (PR#16399)
  • Calculates time to home, on RTL, taking into account vehicle speed, wind speed, and destination distance/direction
  • Pre-emptive geofence breach (PR#16400)
  • Triggers a breach if the predicted current trajectory will result in a breach, allowing the vehicle to be re-routed to a safe hold position.
  • Airframe Scripts
  • The syntax for setting defaults was changed and custom scripts require an update
  • See PR#16796 for an example.
  • Safety (switch) defaults to off (motors are disarmed, but servos / flaps can move)
  • Safety switch is latching: Once it is disabled, it will stay disabled
  • Land detector: Expand land detection to use the ground distance if a distance sensor is present
  • Added support for IRC Ghost including telemetry

Sensors

  • Magnetometer calibration faster and more robust
  • new soft iron calibration coefficients
  • automatically determine the rotation of external sensors
  • Optimized rate control sensor pipeline (minimal inner loop end-to-end latency)

Hardware

The release includes new hardware support for the following boards, peripherals, and accessories:

These are removed:

  • Removal of discontinued Intel AeroFC

MAVLink

  • MAVLink Ethernet configuration (PR#14460)
  • MAVLink Ethernet channel settings such as UDP port, remote port and broadcast mode now can be changed dynamically via parameters.
  • Support for querying COMPONENT_INFORMATION (PR#16039)
  • Parameter metadata is now automatically synchronized in combination with QGC daily.
  • This new message allows any MAVLink system to request rich hierarchical information from an autopilot, i.e., to understand which commands are supported in missions or to get parameter metadata. This message was introduced primarily to help GCS better understand autopilots (RFC: mavlink#1339)

Commander

  • Commander: use control mode flags and cleanup arm/disarm (PR#16266)
  • Consolidate scattered arming requirements in arm_disarm(), and, keeps the vehicle_control_mode last state in commander
  • Commander: Separate out manual control setpoint processing (PR#16878)
  • Adds a new class ManualControl for handling manual_control_setpoint and handles RC loss, RC override, and RC arming/disarming

Multicopter

VTOL

  • RTL improvements (PR#16377)
  • Hardens the RTL safety failsafes taking into consideration the many edge cases when trying to land, depending on the current vehicle mode (Multicopter vs Fixed-wing)
  • Fixed-wing / VTOL significant TECS improvements

Control

  • Dynamic Notch Filter updated with Gyro FFT (PR#16385)
  • Adds dynamic notch filtering to the gyro control data resulting in much smoother control
  • Multi-EKF enabled by default on stm32f7 and stm32h7 boards

GPS

  • The GPS protocol now defaults to u-blox for faster startup, and GPS_x_PROTOCOL needs to be changed if another GPS is used.

NuttX

Nuttx was upgraded from 8.2+ to NuttX 10.10.0+ (@ 904a602c74dc08a100b5c2bd490807de19e73e10)

    ::: info This Knob will cycle through the correct values from low to high. To avoid damaging the crystal. We want to use the lowest setting that gets the OSC running. See app note AN2867 It will take into account the rev of the silicon and use the correct code points to achieve the drive strength. See Eratta ES0392 Rev 7 2.2.14 LSE oscillator driving capability selection bits are swapped. :::
