Arducopter 4.0.3 - AUX as RC channels problem

Cube Autopilot
1

Hi

I use Pixhawk Cube-orange with Arducopter 4.0.3 frame type: quadro X.
I would like use AUX (1-6) as RC channels (RC9-RC14). In status window
chin9 - chin14 is pwm level 0 despite from Radio is signal 1000-2000us.
How solve this problem??

Thanks:)

Change BRD_PWM_COUNT to the total PWM channels you need

Hi

Thanks for answer:) I tried it with different number settings ( 4 ,5 ,6,7…14) but still
chin 9-14 is 0 level.

In link below is successful configuration for AUX.

He use Arducopter V 3.3 and has ,1:RCpass Trough" in RC…_Function.
In Arducopter V4.0.3 I don’t have this option in RC…_Option.

Do You have idea how solve it?

Thanks:)

The SERVO settings are what you are after.
The RC settings are inputs from the reciever, and SERVO settings are outputs to motors and similar.

For AUX1 output use SERVO9_FUNCTION
To set it to mirror a RC input, set SERVO9_FUNCTION,(51 to 66) to suit your RC input channel.
Setting SERVO9_FUNCTION to value 1 (RC Passthrough) would pass RC channel 9 to servo9 output. RC Passthrough would rarely be used - it’d be better to set the specific RC channel.

If you’ve got some specific function in mind, like Camera tilt, Landing Gear or Sprayer - then better to set that function and let the flight controller operate it under certain conditions, so you dont need to be flicking a switch on your transmitter unnecessarily. Works better in Auto mode for missions too.
You’d obviously also need to set up other associated parameters for that function.

Thanks:)

I made settings Servo_9 Function for RCIN 8 and it works but for RCIN9-14 still not.
Why pixhawk don;t see RC9 and RC 10 input from RC receiver?

Are you able to see those rcin channels from the rc calibration in Mission Planner?

Hi

I still don’t see RC 9-RC 10. I have Flysky FS-IA10B 10 channel Receiver.

Can you verify that your transmitter is sending on those channels?

Pretty late to post, Thanks Alvin you just clarified if Aux 1 is Servo 9 or Aux 6 is 9!! Will test it.

As for OP, are you sure you’ve connected Reciever via SBus & not Encoder? PPM supports 8 channels but SBus can go till 16
