Servo Control/Channel Forwarding in ArduPilot

[@chrisreinhardt5136]

Love all your videos, learned a lot thanks!!! What I see missing from your channel and basically the internet, is help with the Radiolink Mini Pix.

[@Painless360]

I've not used one here... Happy flying!

[@mohammadhoseinyousefi6948]

Thanks for your very good and excellent video 👍👍👍

[@Cmensailing]

Thank you painless!

[@thercrv8202]

I would love to see retractable landing gear setup using Taranis, Pixhawk and a LGR control module. I've been going nuts trying to get my Pixhawk to do something, anything, with my Tarot X8 Retracts. The Receiver does it just fine, but I want the features Pixhawk offers, just up and down isn't satisfying for me. I've tried to get 3 different Pixhawks to work my retracts and have never even got a squeak from any of them.

[@Painless360]

Sounds like you're missing something as you can forward the RX channel as shown and it should work in the same way. Automation is then possible.. Best of luck

[@hermannbakouan3883]

Thanks for your excellent video. I use APM 2.8 and I would like to connect two servos to control a robot arm to my APM and I cannot do it

[@jalpa9642]

Thank you so much Lee...! I have a Quad-copter it does not have any Servo's yet but maybe someday....? =)

[@Painless360]

Gimbal, landing gear, drop mechanism.. :)

[@Stoykofky]

thank you sir

[@thedunco]

Where can I get a BEC like that? I looked the one you're using up and it's discontinued and out of stock everywhere, and anything even remotely like it is backordered. Is there another one you'd recommend? If I can't do it with a standalone BEC, how do you do this with an ESC? Thanks though, very informative.

[@Kholeta]

thank you for the video, my question is how did you figured out that position 8 is the right one for this servo ?

[@Painless360]

You pick the output in mission planner as shown. If you are confused about the mapping there are guides in the Ardupilot wiki.. Best of luck

[@ErenSahin_96]

Hello, I am trying to make a fixed wing UAV. via Task Planner When I selected the aileron and elevator options it wasn't turning fast enough. I played with min-max-trim settings but I didn't get any results. It spins faster when I connect it to a port like RC5. What settings do I need to change to rotate the wings? I am providing power from the BEC output of the ESC. Could this have something to do with this?

[@Painless360]

Check out the settings available for the flight mode you are using, max anglescan usuallybeadjusted. Also, check out my series on building an Arduplane... best of luck

[@BestGorony]

Hello. I am a new user of cube orange. I have a question. Can you tell me please why servo doesn't work? I am using futaba s14.

[@Painless360]

It could be a lot of things - check out my builds aimed at new users on the channel for things to check. Best of luck.

[@OzgurJohn]

Hi, it says "SERVO5_FUNCTION=10 on disabled channel" Strange when i select esc as "normal" servo works but when i select dshot300 or 600 it stops working

[@Painless360]

Could be that output are often grouped into sets and you have the ESC on a channel that conflicts.. Happy flying

[@creative2527]

thanks aot from somalia

[@kurdkurdo989]

Hello mr lee i have problem with my radio T14SG the left aileron is working ok but the right one does not! Although all params and setting are correct please help even if its costly im willing to pay

[@Painless360]

Not all servos move the same amount. I'd check that it isn't the servo... Best of luck

[@haykohayrapetyan1721]

Can you please link the video in which you are showing how you fully calibrate the Taranis Q X7 for a plane in this video ?

[@Painless360]

Link to the series is in the video description... happy flying

[@נהורוייס]

hi lee i got pixhwak 2.4.8 and try connect the servo via pixhwak when i use ubec but it dosnet work and the servo dosnt move you have some idia?

[@Painless360]

Please see my Pixhawk for beginners series. It sounds like you are missing something basic. Best of luck

[@aliwahoud2952]

It's possible to see the servos/actuators degree movement on the mission Planer??? Instead of PWM?!

[@Painless360]

I'm not aware of a way to get position information back form the cheap servos we use in the hobby...

[@avrahamcohen2134]

Thanks for the informative video. I do have a question for you. Since all the ports in my receiver are taken, I would like to ask you how can I set the servo to work in case I connect the servo to the AUX1 port (of the FMU-PWM-out) on the PM07 board (I have the Pixhawk4 Flight controller). Where do I set it inside Mission Planner? In QGC it is being done by setting the "RC_MAP_AUX1" parameter to match the exact channel on the RC. Thank you very much

[@Painless360]

No idea. Please post the answer when you get it working..

[@avrahamcohen2134]

@@Painless360 Well, a friend of mine just found the solution for me. Basically, in mission planner there are 16 servo functions. First 8 servo functions are not relevant in this scenario. You need to use the last 8 servo functions for it. So in order to set it, you first need to have BRD_PWM_Count set to 8 and set SERVO9_Function (for AUX1, or SERVO10_FUNCTION for AUX2, and so on) to the channel you want. There are several value options. But in short, 51 means channel 1, 52 means channel 2... 58 means channel 8 and so on. So, for example, if you want AUX1 to be controlled by channel 8, so you set SERVO9_FUNCTION=58.

[@marceloenciso6665]

Trim, min and max changes are not working, why it could be? the servo doesnt react to changes in those parameters.

[@Painless360]

What troubleshooting have you already tried?

[@RickardoPandiangan]

Hi painless360. I have cube orange, and building vtol quad with engine. since main out has consumed by motor vtol and control surface, so i need aux for days I tried even with pix1, different firmware finally aux in pixhawk1 working and I didnt know how. but cube still cant produce any output at aux but working fine with input. can you tell me how to activated aux output?

[@Painless360]

If you want to use all 6 Aux ports for Servo’s set the BRD_PWM_COUNT to 6 and supply 5v to one of the AUX power pins so that all of them are powered..

[@RickardoPandiangan]

@@Painless360 I will try, thanks, but I have problem, main out from 5 to 8 has output at servo output but no pwm at pin 4 to 8. does my pixhawk was broken?

[@RickardoPandiangan]

@@Painless360 with firmware 4.3.7 the bar at servo output display the pwm level at aux if any. But at 4.1.x it did not display the bar servo output at aux. But there are pwm out but not displayed at GCS. I think it has inconsistent behaviour.

[@power-max]

When I enable one of the servo output, the pixhawk stops receiving the RC signal, although my yappu telemetry continues to work. What's going on?

[@power-max]

It seems that when it is enabled radio failsafe is triggered, followed by "no RC receiver" but only if I enable one of the auxiliary channels

[@Painless360]

On what flight controller? How is the servo output powered? I'll need more detail...

[@peterhawke6603]

Im using a Matek H743-wing board flashed with Arduplane (with Q Groundcontrol on a Mac). How do I configure the manual pitch and roll parameters for the manual flight mode? Previously I'd set this in the radio using weights and expo, but I can't locate the same equivalent parameters in the parameter list within Q Groundcontrol. Any help is apprecaited.

[@Painless360]

No idea, I don't use that. Best of luck!

[@juanwanna9433]

I didnt understand how you power the servo, can you explain a bit more? I'm doing this big proyect at school and im really confused. Also, can i use a multichannel reciever in the pixhawk, do i have to connect the servos to the multichannel reciever or can i just connect them to the pixhawk? Edit: Sorry for my english

Please check out the ardupilot wiki and my new Pixhawk 2020 series. Best of luck!

[@juanwanna9433]

@@Painless360 and if my receiver doesn't have a sbus, can I still use it with the pixhack cube?

Not easily. Check the wiki to look at the PPM support.. best of luck

[@alan6708]

Mr Painless, i am attempting to put gps on my tbs 2in1 fpvision can you perhaps point me in the right direction, i have looked on the tbs website and they do sell one but is it plug and play, would you know ? I am still loving fpv and your videos although recently as you can expect not done a great deal other than try to repair my Parrot Anafi with a failing eyesight and French engineering i found it impossible which is y i would like it to be plug n play and the other reason i cannot fly line of sight whereas fpv is perfect for myself. Best wishes, Al..

[@Painless360]

When TBS say 'plug and play' it usually means with compatible kit. There are no standards for cable layouts or connectors in the hobby. I've created a series on the early TBS PowerCUBE stacks. GPS support is usually only worth doing if the flight controller is running ArduPilot or iNav. If it's not then all you'll get are GPS co-ords and a very basic 'rth' function from Betaflight.. See my iNav and Ardupilot builds.. Best of luck!

[@alan6708]

@@Painless360 thank you , thats all i wanted to know before making a decision also i did try to find your video but without luck as i do remember at the time you did a couple of videos on the powercube, i have stuck with this set up because of the ease of the build and been rewarded in making a very light 7 inch quad (334g) anyways pal thanks for your advise and lets see. Best wishes, Al

Can I plug 2 servos for 1 input so that they run simultaneously?

Yes, watch for power requirements.. happy flying

My servo output tab is LOCKED. the drop boxes do not open and i cant manipulate servo reverse from there.? what do to? how to get it open? its too slow doing changes from the "full parameter list"

[@Painless360]

Version, hardware and things you've tried already?

[@globaldesi2956]

So which means pixhawk doesn't provide power to servo if didn't connect a external power supply I

[@Painless360]

I don't understand what you are asking...

[@BensMiniToons]

Yes you need a BEC to one of the servo power pins. all the power pins are one wire. So powering slot one makes them all work. (◔◡◔)
