Dear all,
I use arduplane 4.0.5 on Cube black.
I set BRD_PWM_COUNT = 6, RELAY_PIN=-1,
and set servo9_function = 1 (RC path through).
But, aux1 output 0 on status of mission planner.
Also I checked it on pixhawk1 with arducopter 3.6.12,
it was same.
What do I need to get the PWM signal from AUX?
Thanks.
With SERVO9_FUNCTION set to 1 RC chan 9 will be the input to control it. Is that the channel you have configured as the input to control it?
Dear Dave-san、
With SERVO9_FUNCTION set to 1 RC chan 9 will be the input to control it.
Thanks, it is mistake.
I changed it to 51, RCIN1, reboot, and armed to check.
But it output 0 in Status of Mission planner.
ch1-ch8 out are ok.
ch9-16 are 0.
Is there anything else I can do?
Thanks.
Explain what you are trying to do with an input from RC 1, maybe that will help. That would normally be the Aileron chan.
Dear Dave-san,
RC1 is just test signal.
I want to use servo motor as independent function during flying or hovering with arduplane.
Works for me on the bench. In the Status screen ch9out changes pwm with RC chan 1 input which is the roll (aileron) stick in the configuration. A servo connected to Aux9 also moves. This is with Copter but I don’t think it will make a difference with Plane.Post your parameter file.
Param file I attached was saved yesterday.
Now,
RELAY_PIN,-1
RELAY_PIN2,-1
RELAY_PIN3,-1
RELAY_PIN4,-1
RELAY_PIN5,-1
RELAY_PIN6,-1
BRD_PWM_COUNT, 6
I don’t know what the problem is. I set this up duplicating every parameter from your file that would affect this and it works. You have RCIN1 (51) set on Servo 9 & 10. When I move Chan 1 (Aileron/roll) both chan 9 & 10 change output on the status screen. Attached is my parameters, use Parameter Compare and figure out what’s different. I don’t see anything significant to this issue.

Dear Dave-san,
Finally, I found it.
This is the screenn connected by telemetry.
servo9-14 are set 0. No change.
And this is the screen connected by USB cable.
servo9-14’s function are set 51, and it shows rc1 input signal value.
In both case, I connetecd servo motor to AUX 2ch and checked the motion by transmitter. It moved well.
So, I would like to conclude that it is a bug of mission planner or firmware.
Thank you.
There is not a bug that I’m aware of and not sure what you found. This is the same configuration as you describe connected via telemetry. RCIN1 configured on Aux 9-14. All working fine. Perhaps you should update Mission Planner to Latest Beta.
Dear Dave-san,
Michael-san told me to enable mavlink2 on the telemetry port.
And it works well!
Thank you.
