No functional change, but this avoids numerical issues in the check routine. Since the routine will tend to false positives, we will tend to send more param updates than required in case of numerical noise of the float representation. This is desired, as we prefer to send two updates rather than not sending one.
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
two xml log files are generated for each rostest. they're named according to the launch file, which is reused for each mission test. currently subsequent tests overwrite the previous test's logs. this renames them after they're generated, appending the mission name to the end of the file name.
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
