929bbc8c3f added (untested) flag to disable tricopter servo updates when unarmed.
tri_unarmed_servo to 1 (default) always updates tri servo whether armed or not.
tri_unarmed_servo to 0 will only send servo signal to tail servo when armed.

98d0581ac2 part 2 of ?? of mw2.2 merge (still not flight-tested, so no binaries)
defaulted to looptime of 3500 (yea, yea)
rewrote baro stuff to match mwc2.2 - both supported sensors now return temperature and pressure, which is used in altitude calculation code
rewrote hmc5883 driver to include calibration inside the driver file instead of calling parts of calibration from userspace. it will now blink LED1 while calibrating
some parts remaining to do.

491b3627f6 begin initial merge of 2.2 features
mw2.2-merged stuff:
* implemented profiles 0-2 (called 'setting' in mwiigui)
* merged in MSP changes including profile switch
* cleaned up rc / aux switch stuff in mw.c based on 2.2 rewrite
* main loop switch for baro/sonar shit adjusted
todo: basically the rest of 2.2 changes (i think some minor imu/gps/baro updates)
baseflight-specific stuff:
* made boxitems transmission dynamic, based on enabled features. no more GPS / camstab trash if it's not enabled
* cleaned up gyro drivers to return scale factor to imu code
* set gyro_lpf now controls every supported gyro - not all take same values, see driver files for allowed ranges, in case of invalid lpf, defaults to something reasonable (around 30-40hz)

maybe couple other things I forgot. this is all 100% experimental, untested, and not even flown. thats why there's  no hex.
merge is still ongoing.

4ed57b2696 fix for airplane pwm mode - variable wasn't initialized, resulting in non-working motors on some compilers.
synced angle/horizon mode stuff from mwc. no idea what it does.
perhaps the most important part of this update:
-errorAngle = constrain(2 * rcCommand[axis] - GPS_angle[axis], -500, +500) - angle[axis] + cfg.angleTrim[axis];
+errorAngle = constrain(2 * rcCommand[axis] + GPS_angle[axis], -500, +500) - angle[axis] + cfg.angleTrim[axis];
(which means GPS might actually work).

98cba890e1 moving towards custom mixer table and proper fixedwing mixer.
refactored all of mixer.c to use tables instead of hardcoded mix.
custom mixer is stored in flash, but currently has no UI to configure it.
do not choose mixer CUSTOM in console.

hover-tested QUADX, if upgrading anything else, please carefully check motor response first, preferably without props on heavy models.

staring to merge back in airplane/flyingwing mixes
fix for tri servo display - mwc moved it to servo[5] again, gui was broken, function not.

c98113b82c synced with mwc 2.1. it's suprising how many "new" things in 2.1 didn't actually matter on a real platform.
removed camtrig stuff since it wasnt possible. somewhat replaced with aux forwarding (see below)
2.1 buzzer code changed, untested.
removed flying wing mixer. nobody used that. 
added alt_hold_throttle_neutral, nav_slew_rate and looptime configuration to cli. default looptime set to 3000. changed default gyro_cmpf to 400 to sync with 2.1.
increased bmp085 oversampling
added gimbal_flags (bit 4 set) flag which, in PPM mode, forwards AUX1..4 to the lower 4 PWM outputs instead of using them as motors. set gimbal_flags=8 to test it out. output is fixed to 50Hz.
merged 2.1 gps changes (not many)
casting in gyro smoothing (nobody uses that anyway)
calibrate accel in gimbal mode, set smallangle in gyro-only mode
vtail4 mixer fix
flight tested on quadx w/ppm.

replaced some uint8_t -> uint32_t for loop counters - saving 4 to 8 bytes of flash each time. thanks goes to thee 35+ years of C experience kicad guy.

feature TELEMETRY to enable it. when armed, telemetry is sent out the TX pin. It must be connected to 'Rx' pin of FrSky telemetry receiver via a level shifter. When disarmed, port goes back to 115200 bps for GUI.
fixed a typo in imu.c introduced by  GYRO_INTERLEAVE junk.
todo: just switch serial speed instead of reinitializing everything.

Remember I don't test any GPS functionality at all, so if this makes your quad fly towards North Korea at over 9000cm/sec, this is NOT my problem.

cb334ecf47 fixed acczero offsets to 0 on initial eeprom cleanup
added fifo mode to adxl345 driver, currently disabled. work in progress.
fixed output for PWM 5-8 when used with PPM + camstab + abovequad configs.
fixed baro, now alt-hold actually works. silly copypaste typo.
trashed all remaining parts of power meter and lcd configuration stuff. useless.

9e5504acd8 added a fix for roundf() and friends for keil
added float-based acc lpf, acc_lpf_factor values now changed, its 1/factor now, values 60+ and larger filter heavier.
playing with release MPU6050 hardware, looks like acc1G is fucked, as predicted
bug in serial output (forgot to output armed bit to GUI, estalt is /10)

703234b608 renamed 'tilt_*_prop' stuff into gimbal_[axis]_gain and added more dynamically-configurable gimbal/camstab stuff into cli.
whitespace fixes in mw.h and trashed the old XA-XB based mixer setting leftovers.
settings are cleared again due to updated config struct.

58eb2b966f added configurable motor and servo period settings (50-498Hz). both set by cli, default is 50 for servo, 400 for motors.
removed feature digital_servo since its now set by cli instead.
added proper tx end check into uart, to remove delay inside printing out set values and tx buffer overrun during help()
instead of passing a bunch of params to pwm driver, made a config struct
fixed a bug in gps baudrate
fixed typo in stmloader.c
whitespace / indentation cleanups in various drivers
