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) 6 (flaperon). |
|
|
|
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 |
|
factors (to reverse the servo movement) and adjust the offset, scaling and |

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. |

|
------------ |

|
|
|
This mixer assumes that the wheel servo is set up correctly mechanically; |
|
