FX-79 Delta-wing mixer for PX4FMU
|
|
=================================
|
|
|
|
Designed for FX-79.
|
|
|
|
TODO (sjwilks): Add mixers for flaps.
|
|
|
|
This file defines mixers suitable for controlling a delta wing aircraft using
|
|
PX4FMU. The configuration assumes the elevon servos are connected to PX4FMU
|
|
servo outputs 0 and 1 and the motor speed control to output 3. Output 2 is
|
|
assumed to be unused.
|
|
|
|
Inputs to the mixer come from channel group 0 (vehicle attitude), channels 0
|
|
(roll), 1 (pitch) and 3 (thrust).
|
|
|
|
See the README for more information on the scaler format.
|
|
|
|
Elevon mixers
|
|
-------------
|
|
Three scalers total (output, roll, pitch).
|
|
|
|
On the assumption that the two elevon servos are physically reversed, the pitch
|
|
input is inverted between the two servos.
|
|
|
|
The scaling factor for roll inputs is adjusted to implement differential travel
|
|
for the elevons.

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.

Inputs to the mixer come from channel group 2 (payload), channels 0
|
|
(bay servo 1), 1 (bay servo 2) and 3 (drop release).
