Aileron/rudder/elevator/throttle/wheel/flaps mixer for PX4FMU
|
|
=======================================================
|
|
|
|
This file defines mixers suitable for controlling a fixed wing aircraft with
|
|
aileron, rudder, elevator, throttle and steerable wheel controls using PX4FMU.
|
|
The configuration assumes the aileron servo(s) are connected to PX4FMU servo
|
|
output 0 and 1, the elevator to output 2, the rudder to output 3, the throttle
|
|
to output 4 and the wheel to output 5.
|
|
|
|
Inputs to the mixer come from channel group 0 (vehicle attitude), channels 0
|
|
(roll), 1 (pitch), 2 (yaw) and 3 (thrust) 4 (flaps).
|
|
|
|
Aileron mixer (roll + flaperon)
|
|
---------------------------------
|
|
|
|
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.

Elevator mixer
|
|
------------
|
|
Two scalers total (output, roll).
|
|
|
|
This mixer assumes that the elevator servo is set up correctly mechanically;
|
|
depending on the actual configuration it may be necessary to reverse the scaling

Rudder mixer
|

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.

Wheel mixer
|
|
------------
|
|
Two scalers total (output, yaw).
|
|
|
|
This mixer assumes that the wheel servo is set up correctly mechanically;
