IMPORTANT NOTE: you will loose all previous setting after upgrading to this version.
!!PLEASE, SAVE SETTINGS TO FILE BEFORE UPGRADING!!

  • Bug fixed: multiple YAW turns caused variable overflow and instability
  • Bug fixed: if the system starts in the YAW lock mode, the camera can accidentally  rotate to fixed angle.
  • Bug fixed: in Follow PITCH mode, if camera is pitched by 30-50 degree, ROLL looses horizon level if panning by YAW.
  • Follow PITCH mode extended by the new setting to configure the ROLL axis lock-to-follow transition.
  • If Flight Controller (EXT_FC) is connected and calibrated, the system becomes more stable in the bigger range of inclination angles (even pitched +-80 degrees)
  • Battery monitoring and buzzer:
    • Voltage drop compensation (PID becomes stable during whole battery lifecycle)
    • Low-Voltage alarms and motor cut-off
      (This feature will be supported on some newest boards or old ones with the hardware mod. See user manual for details.)
  • RC mapping improved: Any of PWM, Sum-PPM, or Analog modes may be set for any of RC inputs separately.
    • it lets to use YAW-encoder or joystick together with RC control or External Flight Controller
    • it may be required to re-configure RC inputs after firmware upgrade
  • RC mix option: you can mix 2 inputs together before applying to any of ROLL, PITCH or YAW axis. It lets to control camera  from 2 sources (joystick and remote for example)
  • Serial API extended by the ‘C’ command (camera control). Example written in C++ for Arduino is provided in doc.
  • New option to limit angular accelerations in case of hard RC or Serial control (useful to prevents jerks or skipped steps, smoother camera control, less impact on multirotor’s frame)
  • PID settings: I-term internally multiplied by P-term to increase I response when P is high.
  • “Compensate acceleration” algorythm removed to free up program space for more important features
  • (GUI) New Full-screen mode available to better fit GUI in small displays
  • (GUI) Bug fixed: firmware upgrade fails if working path contains spaces.
  • (GUI) New button to switch motors ON/OFF
  • (GUI) Italian and Czech translation (thanks to Iacopo Boccalari, Lubos Chatval)
  • (GUI) 2 new high-contrast themes for outdoor usage
  • (GUI) New red marker: shows RC controlled angle that gimbal should maintain
