Community Q&A

  • @david_s5 is asking for flight testing on the NuttX changes: https://github.com/PX4/PX4-Autopilot/pull/17653
    All the bench tests with all the drivers succeeded. It would be nice to have someone verify there’s nothing different in a real flight. Otherwise this will probably get merged soon.

  • ECL was merged into the PX4 repository and the repository will be archived.
    The latest fixes will get ported to a point release on 1.12
    The reason for doing that is a lot of maintenance cost for no benefit. There’s only some issue during transitions but we will get over those soon.
    We’re considering to also merge the Matrix library.

  • Vatsal Joshi: Support for the Raspberry Pi microcontroller board
    NuttX has support even for dual core use.
    For a start using MPU6050 I2C tested first
    plan to use MPU6000 over SPI
    Discussion about NuttX support

  • Dhruv Upadhyay: Is interested in getting closer into the dev team and is looking for a good issue to start with. He’s currently interested in low-level driver work but currently doesn’t have hardware access.

    • Something really useful but not too easy might be to solve the bus reset problem. Such that drivers don’t have to handle bus resets one by one but there’s a general automatic structure for that.
    • BLHeli passthrough is an idea. BLHeli ESC connected to the flight controller can talk through it to the BLHeli tool on the computer.
    • Suggestion to continue gudance on the #hardware channel on Slack
  • @dagar Output mapping discussion

  • Discussion about UAVCAN v0/v1
    How to decide compile time what’s supported and how to enable one or the other runtime.

There will likely be another point release with the latest ECL fixes mostly because of this very helpful finding: EKF covariance prediction stability improvements by bresch · Pull Request #1026 · PX4/PX4-ECL · GitHub
