These gimbals are probably quite rare by now but it makes sense to keep the functionality given it can e.g. be used by simple servo gimbals for sensors other than highres cameras. The stabilize flag can also be re-used for gimbals which are capable of stabilizing pitch and roll but not absolute yaw (e.g. locked to North). For such gimbals we can now set the param MNT_DO_STAB to 2. We still support configuring which axes are stabilized by the MAVLink command DO_MOUNT_CONFIGURE, however, this is generally not recommended anymore. vmount: fix incorrect check for bit flag mavlink_messages: remove debug message Signed-off-by: Claudio Micheli <claudio@auterion.com> use device id remove debug print gimbal attitude fix mistake clang tidy fix split: - gimbal_attitude -> gimbal_device_set_attitude, gimbal_manager_set_attitude - gimbal_information -> gimbal_device_informatio, gimbal_manager_information add gimbal protocol messages to rtps msg ids support set attitude for gimbal directly speaking mavlink clean up gimbal urob messages vmount: address a few small review comments vmount: split output into v1 and v2 protocol This way we can continue to support the MAVLink v1 protocol. Also, we don't send the old vehicle commands when actually using the new v2 protocol. vmount: config via ctor instead of duplicate param vmount: use loop to poll all topics Otherwise we might give up too soon and miss some data, or run too fast based on commands that have nothing to do with the gimbal. typhoon_h480: use gimbal v2 protocol, use yaw stab Let's by default use the v2 protocol with typhoon_h480 and enable yaw lock mode by stabilizing yaw.
PX4 Drone Autopilot
This repository holds the PX4 flight control solution for drones, with the main applications located in the src/modules directory. It also contains the PX4 Drone Middleware Platform, which provides drivers and middleware to run drones.

- Supported airframes (portfolio):
- Multicopters
- Fixed wing
- VTOL
- many more experimental types (Rovers, Blimps, Boats, Submarines, Autogyros, etc)
- Releases: Downloads
PX4 Users
The PX4 User Guide explains how to assemble supported vehicles and fly drones with PX4. See the forum and chat if you need help!
PX4 Developers
This Developer Guide is for software developers who want to modify the flight stack and middleware (e.g. to add new flight modes), hardware integrators who want to support new flight controller boards and peripherals, and anyone who wants to get PX4 working on a new (unsupported) airframe/vehicle.
Developers should read the Guide for Contributions. See the forum and chat if you need help!
Weekly Dev Call
The PX4 Dev Team syncs up on a weekly dev call.
Note
The dev call is open to all interested developers (not just the core dev team). This is a great opportunity to meet the team and contribute to the ongoing development of the platform. It includes a QA session for newcomers. All regular calls are listed in the Dronecode calendar.
