New Alexmos Encoder Firmware Upgrade

Using encoders with SimpleBGC board gives the following advantages:

1. Prevents motors from loosing synchronization and skipping steps.

2. Provides the information about frame angle and angle of the camera relative to frame, that can be

important for some kind of applications.

3. Can significantly decrease power consumption by using field-oriented control strategy to drive

motors.

4. Increases instant torque the same way.

5. Provides possibility to get information about the camera balance and makes automatic balancing

(with help of extra DC servomotors and moving counterweights).

6. Option to adjust camera position by hands.

7. Increase the precision of stabilization by applying FOC-specific compensations.

 

List of Supported Encoders

AMT203 – absolute (capacitive technology) 12bit, SPI communication

AS5048A,B – absolute (magnetic) 14bit, PWM, I2C or SPI communication, not assembled.

MA3 – absolute (magnetic) 10-12bit, assembled. PWM communication.

2.40b6

Firmware: SimpleBGC_2_40b6.enc.hex (86Kb 4.02.2014)

GUI (Windows, OS X, Linux): SimpleBGC_GUI_2_40.zip (5Mb 4.02.2014)
User manual: SimpleBGC_manual_2_4_eng.pdf (428Kb 2.02.2014)

  • Bug fixed: some parameters are always kept their default values regardless of GUI setting
  • A new algorithm for increased reliability when motor misses steps:  PID gain is decreased, POWER is increased to restore synchronization
  • Follow mode was completely rewritten:
    •  speed can be adjusted in wide range by the “SPEED” setting
    •  acceleration limiter is applied
    •  LPF smoothing is applied (configured in the “RC setting” tab)
    •  Follow for the axes PITCH+ROLL and YAW  can be activated independently
    •  Follow for ROLL axis may be permanently enabled or disabled regardless of camera PITCHing:  to disable completely, set “ROLL start”=90, “ROLL mix”=0, to enable set “ROLL start=0”, “ROLL mix=0”.   (Note, that proper Follow offset calibration for ROLL is required now)
  • Up to 5x more precision with the new PID (increase I-term until oscillation starts and than reduce a little back to get the maximum from it)
  • New menu commands to turn motors ON/OFF.
  • (GUI): new setting for additional POWER in case of big error (caused by missed steps).
  • (GUI): new visual bar to display the actual POWER level.
  • (GUI): new setting to enable estimation of the frame angle from motor’s poles in the Lock mode, like in the Follow mode before. Helps to increase the range of  frame angles where gimbal’s operation is stable.

 

Alexmos 3 Axis Brushless Gimbal Controller DIY Box Assembled

Posted on by — Leave a comment

Fully Assembled Alexmos 3 Axis DIY Box. Box comes ready to plugin. LED Status indicator and Menu Bottom Hard Wired. Option to connect an external LED and menu button in parallel.

  • Alexmos 3 Axis board – not stacked
  • Headers soldered
  • Copper High Dissipation heatsinks mounted
  • Custom 5 wire interconnect
  • 12AWG or 14AWG power leads soldered and terminated with XT60 connector (Total 5 x Pairs Inlcuded)
  • Bluetooth Module Installed
  • Board flashed with the latest firmware, default settings loaded and tested for proper operation. NOT TUNED FOR ANY CAMERA
  • Various ferrite rings will be included
  • Box will mount using standard 2 axis board mounting pattern
  • Built-in Menu Button
  • Staus/Power LED
  • Power Switch
  • Alexmos Buzzer Included

Note: The Mounting pattern is 45mm (Standard Alexmos Board Hole Patttern). The 2 boards will need to be unscrewed from the box in order to mount the box. Enough slack provided to remove to the boards. Tuning to be done using Bluetooth module. The 2 axis board will have to be removed in order to access the USB port. If direct access to USB port is needed a whole will have to be drilled.
