Automatic magnetic declination from GPS coordinates (approximate to 1-2 degrees) (disabled)
Accelerometer bias compensation
Quaternion-based Mahony's DCM IMU (implementation by S. Madgwick)
Ability to lock heading to GPS cource for airplanes
Faster acquisition by initial attitude by using higher DCM kP gain on powerup
Changes to mag calibration algorithm (@HaukeRa's code). Compass calibration now independent from align_mag.
Changed acc calibration to proper 3-axis offset calculation code (same code as for mag). Changed board alignment angles to decidegrees (configurator incompatibility). Removed accelerometer trims (values passed thru MSP are ignored). Accel trim stick combo now adjusts board alignment directly (real-time, without reboot). Removed inflight acc calibration.
FIR filter implementation for different looptimes. Option gyro_cut_hz replaced with gyro_fir_enable (default gyro_soft_filter=3 preset - a very pessimistic filter with fairly large delay but low cutoff frequency for large or very noisy copters)
iNav-related PIDs renamed in CLI to avoid re-usage of old values when restoring config dumps.
PID with back-calculation and I-term anti-windup. Smarter max acceleration and jerk limiting
Initial support for airplane navigation. ALTHOLD, POSHOLD (circular loiter around the waypoint) and RTH should work. UNTESTED! RTH altitude probably needs some work. Autolanding will NOT function at the moment - the AUTOLAND phase will never complete. Absolutely no throttle control at the moment (fully manual control).
Increase delay for bmp085 baro detection. Resolves an issue with bmp085 not being detected sometimes on powerup
Fixed the missing checks for MIXER_CUSTOM_AIRPLANE
Lots of small fixes
Features I2C-GPS autodetection. No need to set gps_provider. If no serial port selected for GPS, feature GPS enabled and I2C GPS connected and detected, gps_provider will automatically be set to '2'
This change adds a brief mention of power requirements and USB power pass-through to the GPS docks. This small but important fact is not mentioned anywhere, though it is obvious if you stare at the board specific documentation long enough. Many larger flight controllers (eg Pixhawk) do pass through 5V from USB, so this is non-obvious to users of those FCs.
It was a little bit hard to read with only two paragraphs, and looking at the raw .md file it was clear that having just two paragraphs was not the original intention.
- add two new CLI paramaters "gtune_settle_time" and
"gtune_average_cycles"
- the settle time is not depending on looptime anymore
- updated default setting to cover e wider range of copters
- remove lower limit for P value for CLI (Zero P is now posible, but
schould be used with care)
- Documentation updates
G-Tune documentation update
G-Tune will only activated and deactivated when armed.
G-Tune should deactivated while the copter is airborne.
Tuned P values will only be stored when G-Tune is enabled while disarmed
and G-Tune was used before.
Enabled for NAZE, ALIENWWIIF1 and ALIENWIIF3 targets
Implement G-Tune for all PID controllers
The G-Tune tuning results will be save if G-Tune mode will be disabled
during copter is disarmed.
Update PID controller and G-Tune documentation
