It was meant as an example for an easy to use interface of a
motion primitive with a minimal implementation. But the implementation
is much worse than the jerk optimized trajectory. We rather
work on making it easier to use. #18390 was a first step towards that.

607aa4d 2021-11-15 Alexander Funke - Wind Plugin: Fixed typo in windGustVelocityMean. Closes#825, fixes#812 Fixed the typo in windGustVeloctiyMean to windGustVelocityMean, so that the parameter in the world file can be correctly read and the mean gust velocity properly set to the parameter's value.
- cmake NuttX build wrapper compile in place instead of copying source tree to build directory
- slightly faster skipping necessary copying (depending on system)
- allows debugging in place
- easier to work directly in NuttX following official documentation
- simplifies overall build which should make it easier to resolve any remaining NuttX dependency issues in the build system
- the downside is switching back and forth between different builds always require rebuilding NuttX, but I think this is worth the improved developer experience
- also no longer builds px4io and bootloader in every single build, for most users these rarely change and we're wasting a lot of build time
The current practice of adding topics to the default set isn't scalable,
as it affects all setups.
By making sure topics are advertised on init, logger can just discard
topics that don't exist. This does not work for all topics, so topics are
specifically marked as optional. It can be extended to more topics later
on though.
This reduces the list of topics by ~35 on a pixracer configured as quad,
and reduces RAM usage by ~1KB.
Be course of the numerical computing error . The normalization of the quaternion can't always equal to 1 precisely. It could occasionally trigger the error"attitude estimate no longer valid". So enlarge the threshold to 1e-6f. That keeps it silence.
- numerically the cutoff frequency not being smaller than 1% of the
sample frequency is probably a better choice, but we're mostly filtering
16 bit data now stored in 32 bit float
The _MAV_PAYLOAD macro casts the value to a char*. Some compilers treat
char as signed, so we were getting negative system and component ids
if the id was >= 128. This caused later comparisons to fail which
resulted in messages not being forwarded.
