Alexmos IMU Temprature Calibration

Alexmos IMU Temprature Calibration

  • IMU temperature calibration and compensation. See user manual for details.
  • (GUI) New tab “Analyze”, see updated user manual for details
  • Notch filters have adjustable gain (0..100%)
  • Bug fixed: frame upside-down detection doesn’t work if “skip gyro calibration” is disabled.
  • Bug fixed: acceleration limiter does not work properly with the big speed setting in the “Follow” mode: camera overshoots target position
  • Minor bugs fixed related to accelerometer calibration

  • (GUI): new option to enable auto-detection of system startup in the upside-down mode
  • (GUI): New interactive dialog to detect sensor orientation
  • (GUI): New interactive dialog to calibrate sensors
  • Second UART port to process Serial API commands: Rx goes to RC_ROLL, Tx goes to RC_YAW. It can be enabled in the RC tab ->”RC_ROLL pin mode”
  • Spektrum satellite new binding and data format options (used in the “Bind RC” command and to decode spektrum protocol)
  • Bug fixed: in the Follow mode when the camera is pitched down about 90 degrees, its not controlled by YAW
  • Bug fixed: calibration of accelerometer in the simple mode did not reset extended mode calibration, making a result of simple calibration not correct.
  • Bug fixed: “Estimate angle from motors” doesnt work in 2.43b6
  • Minor bug fixed with firmware update dialog.
  • Recovery firmware works now with USB connection on v.3.1 “Tiny” boards.

2.43b4

GUI (Windows, OS X, Linux): SimpleBGC_GUI_2_43b4.zip (6Mb 20.10.2014)
User Manual (English): SimpleBGC_32bit_manual_2_43_eng.pdf (933Kb 20.10.2014)
User Manual (Russian): SimpleBGC_32bit_manual_2_43_rus.pdf (1Mb 21.10.2014)

  • New GUI tab “Adjustable variables”  to change system parameters remotely in real-time:
    •   10 slots for trigger-type controls
    •   15 slots for analog-type controls
  • New sound model: if “Beep with motors” option is enabled, gimbal plays various sounds instead of simple beeps.
  • New Serial API commands to communicate with external I2C devices
  • New Serial API commands to store up to 128 bytes of user data in the EEPROM (may be usefull for third-party GUI or external application developers)
  • New RC signal source “API_VIRT_CH1..32” controlled via Serial API to simplify gimbal control (see examples in the specification)
  • PID Auto Tuning should give more precise results because of decreased error threshold
  • Better error handling on writing parameters to the board via slow connection.
  • (GUI) New menu option to save all profiles into single file. This file can be loaded back by standard “Load from file..” command
  • (GUI) New menu option to write all profiles to the board.
  • Updated examples for Arduino: SBGC_Serial_API_Examples.zip (14Kb 19.10.2014)

Alexmos Firmware 2.42B6 Update Released – Autotune Support

Firmware upgrade 2.42b6 – AUTOTUNE Support 

GUI (Windows, OS X, Linux): SimpleBGC_GUI_2_42b6.zip 

User Manual (English): SimpleBGC_32bit_manual_2_42_eng.pdf 

  • 4xPWM servo output with adjustable rate to output virtual channels decoded from RC input, or driven by Serial API
  • PID auto-tuning
  • Adaptive PID gains
  • Digital filters to remove resonances: 3 x Notch filters, 2nd-order low-pass filter
  • Bug fixed: upside-down settings lost after switching to different profile
  • “Frame upside-down” command now inverts RC control for YAW, together with inverting YAW motor and rotating second IMU
  • Bug fixed: should  ignore CMD channel during system init
  • MOTORS_ON command resets system to home position
  • New option for second (frame) IMU: “Below YAW + PID source”. It means, if Frame IMU is mounted below YAW motor, it can be used as data source for PID controller, and in some cases can give better result, than main IMU.
  • (GUI) UI elements re-arranged to adopt new settings and make groupping more consistent
  • (GUI) Separate LPF setting for RC and Follow Mode
  • (GUI) New setting “RC Inverse” (you can use it or switch Min. and Max. angles, as before)
  • Last used profile is saved as default when switched by service button, RC CMD command of from GUI.
  • Bug fixed: s-bus fast mode was not decoded correctly
