Basecamelectronics Alexmos Firmware 2.50b0 (release candidate)

Basecamelectronics Alexmos New Firmware Release 2.60B4

New features

  • New enhanced PID auto-tuning algorithm:
    • Fast and reliable;
    • Finds most optimal PID gains to minimize error of stabilization and prevent self-excitation;
    • Flexible: can tune PID from zero or slightly adjust gains starting from the current values;
    • Able to tune other parameters, like low-pass filters;
    • Has safety interrupts to prevent damage in case of wrong system operation;
    • No GUI connection is required – can be run by the menu button command;
    • Allows to update PID settings in all profiles;
  • New settings “Filters” – “D-term LPF filters” that can help to remove high-frequency oscillations in some setups and allows to set greater PID gains
  • Notch filters are extended: can be used as peak filter; gain is set in dB instead of %
  • Acceleration limiter setting is split per-axis
  • New types of encoders are supported for YAW axis in the regular firmware: PWM and I2C.
  • New option “PID Gain multiplier” to extend the range of  PID settings or link PID gain to adjustable variables, to tune it on-line by the analog potentiometer or RC.
  • Serial API was extended by many new commands
  • Option to disable of using gyro signal from the frame IMU for stabilization, but keep it for a frame angle detection; option to pass it through  low-pass filter with adjustable cut-off frequency. Both options  are useful in the case of high level of vibrations on the frame.
  • Add a support of MavLink protocol for Ardupilot FC connection (beta state), that allows to increase a precision of stabilization and control over gimbal in automated missions.
  • Option to backup/restore IMU calibrations to a file
  • (Encoder version) Motor over-heating protection is improved: more precise model, virtual temperature is shown in the GUI to simplify tuning process; new safety action: alarm and cut-off motors
  • (Encoder version) “Encoder field offset” parameter is calibrated automatically, no frame movement is required.
  • Parameter “Magnetic linkage of a motor” will improve precision of stabilization; new auto-calibration function for this parameter
  • Angle of motors can be used as a source in the “Adjustable Variables” to set a dependency of the system parameters on the camera-to-frame relative position, set by the inner (counting from the camera) and the middle motor’s angles
  • Option to enable 3rd serial port: UART2 (Rx: AUX3, Tx: n/c); option to swap pins with the RC_SERIAL port (Rx: RC_ROLL, Tx: RC_YAW). In the encoder-enabled version, ports are swapped by default.
  • New menu commands to switch to selfie mode by rotating camera 180 degrees from current position or 0/180 relative to home position, by the YAW axis.
  • Several new commands in scripting language; option to use dynamic variables linked to the RC signal sources
  • Option to automatically switch to upside-down mode (both frame and camera) and auto-rotate camera when frame is rotated +-180 degrees over PITCH axis.

Bugfixes

  • Fixed problems with USB connection in “Tiny” boards
  • RC control is slightly improved: smoother “Angle” mode, no overshoot after fast breaks
  • Script parser: properly handles speed below 0.07 degree/sec for very slow time-lapses
  • Fixed problems with the firmware upgrade under modern MacOS versions
  • Many minor improvements of the system performance in various conditions

Phobotic Centerpiece – What’s New

  • Many improvements to stabilization and Autotune
  • Gimbal Analyzer: a new feature available from the GUI that lets you run performance tests on each axis and see how well the gimbal responds on a graph.
  • Follow profiles: each axis can have up to 5 different follow configurations that can be quickly switched from the GUI.
  • Follow presets: each follow profile can be quickly set up by choosing a pre-made configuration from a list.
  • Pole position: easy fine tuning of the yaw home position (see in-app help)
  • Improved R/C position limiter:
    • Added a more intuitive GUI for setting the position limits.
    • In angle mode, the position range is mapped to the R/C travel, to avoid a dead stick range.
    • Also in angle mode, there’s now an option to set the position of the axis when the R/C stick is at zero.
    • In speed mode, the deceleration near the position limits can be made less/more abrupt.
  • Easier setup of R/C follow control
  • Fixed some saved profiles failing to load
  • Fixed R/C angle mode on an axis with follow
  • Fixed LED display of battery status
  • When autotune fails, an error message is now displayed in the GUI
  • Various improvements to the diagnostics sent in support requests
  • Lots of other small improvements & bugfixes
