Copter-3.5.0-rc4 is being released for beta testing over the next few hours (at the time of this post, the auto-builder is still working on it). This has mostly minor bug fixes over -rc3 which are listed below and in the ReleaseNotes.
- Bug fixes including:
a) Baro based altitude estimate fixes including limiting ground temperature to reasonable value
b) Fix 0.6ms lag reduction
c) Fix Invensense IMU driver temperature reading
d) Fix semaphore take during interrupts that may have caused very occasional main loop rate issues
e) Return the Home position if GCS asks for first (i.e. zero-ith) mission command (required for Solo)
1b) may lead to a slight improvement in attitude control especially for small vehicles. This changes was meant to be included in -rc3 but due to a small misunderstanding -rc3 actually had slightly worse lag than previous versions.
1d) may resolve the one ugly crash we saw in which a Pixhawk1’s performance degraded over about 30 seconds. Unfortunately that issue appears to be so rare it may be difficult to know if we’ve solved it.
1e) is for the project to get Solo running on master again.
Thanks for help with the testing! I’m pretty sure we’re almost there.
