How to use 2 axis gimbals

Jump to navigation Jump to search

Two axis gimbals are not officially supported by the STorM32 firmware, but folks worked out how to set the controller up to get that working nevertheless.

Some general points:

  • A 2nd IMU cannot be used, and must be disabled, i.e. the parameter Imu2 Configuration in the [GUI:Setup] tab must be set to “off”.
  • The unused motor axis needs to be disabled, i.e. the respective parameter XXX Motor Usage in the [GUI:Setup] tab must be set to “disabled”.

In addition to these, further points might have to be considered however, see below.

Pitch-Roll Gimbals

Please share your knowledge!

Different people might have different settings which work for them. In order to explore the various solutions, I (OlliW) suggest that each of you add your solution in a separate chapter. Your addition should start with === This is My Name === as first line. THX.

2 axis roll/pitch gimbal, fixed wing.

The only difference is that I disable the yaw motor and also uncheck the yaw motor option in the gimbal configuration tool. Specs/pics/settings to come.

2 axis gopro hero 3 "goodluckbuy" gimbal which included the v1.3 STorM32 BGC with v.64e firmware. Mounted to Tarot 650 Sport

Disable yaw motor, write and save to board. config IMU (1 point). unchecked yaw motor option in config tool and complete setup like normal. Had to play with the "x" and "z" axis settings with this gimbal probably due to how it was mounted. Pretty simple

2 axis roll/pitch home made plywood gimbal for RCexplorer.se V3 Tricopter and GoPro Hero4 Black. Storm32 BGC 32Bit 3-Axis Brushless Gimbal Controller V1.31 DRV8313 Motor Driver from AliExpress/GoodLuckBuy flashed with V.0.70 from the shop and Turnigy 2206-140Kv Brushless Gimbal Motor (11.25 Ohm) . Disabled yaw motor before entering Gimbal Configuration Tool (GCT), skipped yaw motor orientation in GCT. After running setup in GCT, yaw motor was enabled again, so I had to disable it again before I did a new Write+Store. Total weight of gimbal without camera 140g.

Pan-Tilt Gimbals

Rcgroups user vonkross applied the STorM32 controller for a pan&tilt camera application. Inspect these posts (please scan also for follow-up posts):

What I did to go through the Configure Gimbal Tool procedure was temporarily mount a roll motor over the pitch frame with the IMU1 on it. After completing the procedure disassemble/disconnect the roll motor (with power off) and replace the IMU1 sensor on the pitch frame in the same orientation. Then disable roll motor and adjust PID and any parameters involved.
