* Previously, the ELEVON_REVERSE parameter was equivelant in function to the
ELEVON_CH1_REVERSE parameter. These parameter values are found in
g.reverse_elevons and g.reverse_ch1_elevon, and used to map to the radio_out
channels in ArduPlane/Attitude.pde
* It seems the author's intent was for ELEVON_REVERSE to change the sign for
the combination of pitch & roll into ch1 & ch2, as there are already
parameters which change just the sign of ch1 and just the sign of ch2.
* Discovered this bug because I happened to build an elevon airframe which was
not possible to setup with the existing ELEVON_ and RCn_REV parameters.
* This will break existing elevon setups if the user used ELEVON_REVERSE
instead of ELEVON_CH1_REVERSE, since they were previously interchangable.
when we send a GPS_RAW message, set the usec field to the time we got
the fix from the GPS, not the current time. This makes it possible for
aerial photo processing to be more accurate, as the usec field with
more accurately reflect the planes position/time pair
This makes the DataFlash erase much faster (about 6 seconds instead of
about 60 seconds).
We need to test and ensure the behaviour is equivalent apart from the
speed
setting ARSPD_ENABLE to 1 and ARSPD_USE to 0 allows the airspeed
sensor to be initialised and logged without it being used for flight
control. This is very useful when initially testing an airspeed sensor
in a new plane. It also makes it possible to enable/disable the use of
the airspeed sensor during a flight at any time.
When using GPS for yaw correction we need to apply the x and y omegaI
corrections from the _omega_I_sum in the period before we get to the
minimum ground speed for GPS yaw correction. Otherwise we get a large
sudden omega_I change on takeoff.
add popouts in config/setup
add more text to hud heading nw,ne,sw,se
add 5 m filter to antenna tracker
add refresh param buttons
remove the word old, as people still want it.
modify telem playback interface with slider bars
add posible fix to bad grid spacing
move mavlink code.
removed unneeded d_rate_filters
updated Nav routine to handle faster GPS updates
moved calc_XY_velocity to GPS read
added check for duplicate GPS reads
shrank speed filter to avoid latency
removed unused forward estimator code
placed code for switchover to gps.groundspeed at 1.5m/s
added clamp for D term when below .5m/s to eliminate noise
added hybrid I-term based on speed error and position
changes Loiter D term to use position rather than acceleration to avoid noise
Merged CopterLEDS and Piezo functions to eliminate pin conflict on APM2. Created new Parameter bit to turn piezo function on and off from MP. Moved GPS and Aux pin assignments to allow commonality between APM1 and 2. Set LED_Mode parameter default to 9 in order to make CopterLEDS completely backwards compatible with old Motor LEDS and Piezo code. Legacy users should see no difference.
