Community Q&A

  • @david_s5 12 cell Li-po/ion power module support: So far fmu-v5x usually comes with a 6S compatible INA226 power module. Holybro will be providing a power module with an INA228 on to support 12S batteries. The software support for it to work out of the box is currently work in progress.

  • @MaEtUgR Pull request to allow configuring a margin for the horizontal multicopter control authority when the vertical control is saturated: https://github.com/PX4/PX4-Autopilot/pull/18205

  • @david_s5 and @rroche had an issue recently where the virtual joystick would make an autopilot to beep for presumably failsafe when using it over USB:

  • Vatsal Joshi: What are the instances where you get a PWM count error. He’s configuring PWM and then tries to test it but gets the error. It’s likely a configuration issue. pwm_out test should get all outputs to fade from low to high values.

  • Dave Walter: Is contributing to the documentation explicitly on how to integrate a stand-alone smart gimbal with MAVLink and PX4: https://github.com/mavlink/mavlink/issues/1678
    In the hope to get better manufacturer integration from e.g. Trillium, Nextvision, … so if you’re a manufacturer or gimbal-interested developer chime in. @JulianOes is very interested and already joined the discussion.

  • Farhang Naderi: Asking what should be tested. Please test the new point release especially also with the newest boards. Thanks!


New point release is out 1.12.3:

In-Depth discussions

  • Device tree: It would be nice to have a UI showing what devices are connected on which bus and the user can select what to enable and it will be required from thereon.

If you have any feedback or corrections please comment on this post.
