Implementation is DMA buffer based, just like the WS2811 LED Strip code,
so that there is minimal impact on flight performance.
Currently the code is mutually exclusive with the LED_STRIP code and
there is no means to set the transponder code.
Updated SPI driver (SPI3 on F3 targets)
AK8963 Mag support (part of MPU9250)
MPU9250 SPI support via MPU6500 driver
Updated LED driver for alternative LED sets
Enable gyro intterupt for AlienFlight F3 targets
Update AlienWii/AlienFlight documentation
Rename AlienWii to AlienFlight
Disallow arming if system load > 100 (waiting task count > 1)
Dont show inactive tasks in CLI
Realtime priority task and guard interval implementation
Dynamic guard interval. Bugfix for realtime scheduling hickups
Optimisations
Compile out CLI command help and CLI tasks command for CJMCU
Naming fixes // re-Add Gyro Sync // Fix port issues
modified debug output (currently disabled)

https://github.com/cleanflight/cleanflight/pull/1340
and here:

Tested on FrSKY X4RSB with latest CPPM firmware (non-EU version).
Firmware filename: X4R-X4RSB_cppm_non-EU_150630
In both SBUS and CPPM mode.

Added delay to rxfail detection
All channels are monitored for bad (out of valid range) pulses.
On bad pulses channel data will HOLD the last value for a period of
MAX_INVALID_PULS_TIME (300ms) before starting rxfail substitution.
This should prevent a too aggressive reaction to small dropouts.
---
Init ARM switch rc channel to OFF for safety
Initialize ARM switch to OFF position when arming via switch is defined.
To prevent arming during init when RX is disconnected and/or when RX is
connected but TX is still off.
---
Modified rx_rx_unittest.cc
Adapted because rxInit() parameters changed.
Added tests for ARM switch initialization.
No further tests added.

Move smoothing of rcData to rcCommand
Commit from @borisbstyle pr #1418
rc_smoothing function has changed to leave rcData unchanged in #1418
hardware failures by counting the number of long flashes.
Fix up sensor read API so that code that uses sensors can detect
malfunctions.
If a failure mode occurs in a debug mode the code reboots the system
rather than rebooting to the bootloader.
- Added failsafe flightmode and rc control box.
To make failsafe procedure a separate flight mode and make it possible
to trigger failsafe with an AUX switch.
- Failsafe mode is activated when failsafe is active.
RC link lost is simulated with the failsafe AUX switch.
When NOT armed: failsafe switch to failsafe mode is shown in GUI (mode
tab).
- Activate failsafe mode with AUX switch.
- Prevent arming when failsafe via AUX switch is active (safety issue).
- Make failsafe disarm if motors armed and throttle was LOW (2D & 3D)
for `failsafe_throttle_low_delay` time (__JustDisarmEvent__).
Applied code changes to effectively add pull request: Make failsafe
disarm if motors armed and throttle low #717.
- Use failsafeIsMonitoring() to actually start monitoring.
- Added `failsafe_kill_switch` to code.
When set to 1 (0 is default), the failsafe switch will instantly disarm
(__KillswitchEvent__) instead of executing the landings procedure.
Arming is NOT locked after
this, so the craft could be re-armed if needed.
This is intended for racing quads where damage and danger must be
minimized in case of a pilot error.
- Added `failsafe_throttle_low_delay`, adapted documentation.
Used to adjust the time throttle level must have been LOW
to _only disarm_ instead of _full failsafe procedure_
(__JustDisarmEvent__).
- Updated the failsafe documentation.
- Re-enable arming at end of failsafe procedure.
At the end of a handled failsafe event, that means: auto-landing,
__JustDisarmEvent__ or __KillswitchEvent__, the RX link is monitored for
valid data.
Monitoring is a part of the failsafe handling, which means the craft is
still in failsafe mode while this is done.
Arming is re-enabled (allowed) when there is a valid RX link for more
then XX seconds, where XX depends on the handled event like this:
1. XX = 30 seconds after auto landing.
2. XX = 3 seconds after __JustDisarmEvent__.
3. XX = 0 seconds after __KillswitchEvent__.
NOTE: When armed via an AUX switch, you will have to switch to the
disarmed position at the very end to be able to re-arm.
The failsafe mode will not end until you do.
- __KillswitchEvent__ has now priority over __JustDisarmEvent__
- Apply rxfail values instantly when failsafe switch is ON
- Added missing cases to display.c
Show M when failsafe is monitoring for RX recovery (AND disarming when
armed with a switch).
===
Reworked the code from counter-based to time-based.
- AUX failsafe switch now has identical behavior to RX loss.
- Added RX failure and RX recovery timing.
- __KillswitchEvent__ skips RX failure detection delay (direct disarm).
===
[UNIT TESTS]
Adapted failsafe related unittests from counter-based to time-based
- Added failsafeOnValidDataFailed() to some tests
- Removed duplicate test setup from rc_controls_unittest.cc
- Removed magic numbers from rx_ranges_unittest.cc and rx_rx_unittest.cc
- Reworked all test-cases for flight_failsafe_unittest.cc
