- remove separate flaperon controls input to mixer instead enable spoiler support
- add slew rate limiting on both flap and spoiler controls
- add spoiler configuration for Landing and Descend
- add trimming from spoiler deflection
- FW Attitude control: remove FW_FLAPS_SCL param -->
The flap settings for takeoff and landing are now specified relative to full range.

Aileron/v-tail/throttle VTOL mixer for PX4FMU
|
|
=======================================================
|
|
|
|
# @board px4_fmu-v2 exclude
|
|
|
|
This file defines mixers suitable for controlling a fixed wing aircraft with
|
|
aileron, v-tail (rudder, elevator) and throttle using PX4FMU.
|
|
The configuration assumes the aileron servos are connected to PX4FMU
|
|
AUX servo output 0 and 1, the tail servos to output 2 and 3, the throttle
|
|
to output 4.
|
|
|
|
Inputs to the mixer come from channel group 0 (vehicle attitude), channels 0
|
|
(roll), 1 (pitch), 2 (yaw) and 3 (thrust) 4 (flaps) 6 (flaperon).
|
|
|
|
Aileron mixer (roll + spoiler)
|
|
---------------------------------
|
|
|
|
This mixer assumes that the aileron servos are set up correctly mechanically;
|
|
depending on the actual configuration it may be necessary to reverse the scaling
|
|
factors (to reverse the servo movement) and adjust the offset, scaling and
|
|
endpoints to suit.

V-tail mixers
|
|
-------------
|
|
Three scalers total (output, roll, pitch).
|
|
|
|
On the assumption that the two tail servos are physically reversed, the pitch
|
|
input is inverted between the two servos.

Motor speed mixer
|
|
-----------------
|
|
Two scalers total (output, thrust).
|
|
|
|
This mixer generates a full-range output (-1 to 1) from an input in the (0 - 1)
|
|
range. Inputs below zero are treated as zero.
