Volatile parameters are ones that do not represent a fundamental configuration change but rather than incrementally changing settings. These include logged flight hours or sensor offsets. Marking them as volatile avoids these parameters forcing time-consuming telemetry updates.
Parameters can change not just based on GCS request, but also due to internal code or requests by a different valid connected control authority such a cloud service. This change ensures that all connected systems get updated via MAVLink asynchronously.
This helps subscribers to understand if they should update their parameters or not. We will extend this with other flags such as the current save status and alike.
This marks the learned bias parameters as volatile (as they change in flight without external configuration) and marks them as system level, which should hide them by default from the UI
Most of the incompatitbilities are luckily similar to the darwin build.
- New target OS __PX4_CYGWIN added because in other build environments on Windows defines will very likely be completely different
- added all necessary exeptions to the defines
- disabled priorities completely because on Windows they are defined 1-32 and with all the arbitrary +40 -40 priority settings there were a lot of problems
not only did some threads/"virtual tasks" not start because of out of bound priorities but also the resulting scheduling was totally random and inadequate
with default priorities it ran toally fine during my first tests, should be rethought when windows is used onboard in the future
This is important to have the probation times set up correctly and to silence land detected messages for systems that are not actually flying and just on the bench.
Before the VTOL status would automatically force a commander state update all the time. This saves effort and makes sure the system only updates when it should.
We were running pre-arm checks before when not arming, which led to annoying error messages on vehicles that were on the bench or serviced on the ground. Now we really only run them when trying to arm.
