    is the joystick icon white?

    Hey Jacob is it possible that I can install the dependencies from github to a sd card that isnt flashed with the ardusub software? Too see if the connection still works for qgc?

    The joystick is showing white yea. showed red the first time but we calibrated the controller and that sorted it.

    @jaxxzer
    Do you see activity on the joystick page when you move the joystick and push buttons @KGS_Engineers_twitter ?
    can you arm the vehicle?
    @charlesrov I don't understand the question
    you can just install mavproxy and connect to qgc

    Hi i have some question about connection relay to pixhawk i did connections and arrange button of joystick from qground controller but button didnt work. I didnt explain a lot but if you ask question i will reply for solving this problem.
    I am trying to use relay from joystick

    @jaxxzer
    @Ordineer please show us a parameter file and connection diagram

    @Ordineer
    how will i do it i dont have a lot information about qdc or pixhawk
    i am beginner about this

    @Ordineer
    thank you i will share now

    thank you bro i solved it yesterday i forgot to send message here. Problem is the aux out pins arent enough for trigger to relay when i give 5v from different source it worked.
    And also thank you for replying probably in the future i will need your helps anymore :)

    oh one more thing can i find any source for autonomus driving for ROV via raspberry
    I couldn't find too much information about. Do you know any reserach or project about it.
    Jacob Walser
    @jaxxzer
    You can try navio2

    @Ordineer
    okay thank you i will search about it

    Hi, I'm trying to run ardusub on a BeglaBoneBlue. I've flashed bone-debian-9.3-iot-armhf-2018-01-28-4gb.img.xz and followed steps from here and still get the
    RCOutputAioPRU.cpp:SIGBUS error gernerated.

    So, I also uncommented the line uboot_overlay_pru in the uEnv.txt file, reboot and still get the error
    I'm trying to do
    sudo ./ardusub -C udp:<beagleboneblue ip address>:14550 and still get the RCOutput error. can you recognize what the problem is? I cross-compiled the ardusub in my Ubuntu computer (16.04)

    Thanks!

    I am wondering if it is possible to connect my Adafruit Anemometer https://www.adafruit.com/product/1733 directly into the AC3.3V port on the pixhawk then have it read out on QGroundControl, or would have to use an Arduino and companion computer (raspberry Pi) to read the analog input instead?
    Ordineer
    @Ordineer
    @jaxxzer oh thanks i forgot to remind you about relay. i solved the problem pixhawk aux out doesnt have 5V output because of this reason it wasnt work. And again Thank you so much.
    Jacob Walser
    @jaxxzer
    @jazmyng it's possible for some vehicles like planes, but ardusub doesn't have any concept of wind speed sensors, you will have to modify the firmware to report the adc value, or use companion + arduino.
    jazmyng
    @jazmyng
    @jaxxzer how can i modify the firmware ?

    @jazmyng check our documentation here: https://www.ardusub.com/developers/developers.html

    @NickNothom
    @jazmyng I was able to get my anemometer to work on one of the aux input pins with ArduRover (latest / master firmware). Checking out their code might get you pointed in the right direction.
    jazmyng
    @jazmyng
    Oh okay! I just cloned the entire repository, by ArduRover do you the mean the folder that is APMrover2?
    Nick Nothom
    @NickNothom

    Yes.

    There are some docs here: http://ardupilot.org/rover/docs/wind-vane.html

    Oh wait, yours is different. Yours is an analog output so you will need to hook it up to the ADC input.
    Nick Nothom
    @NickNothom
    There may some useful info in this thread for you. That's where I figured out how to get mine working.
    jazmyng
    @jazmyng
    We actually decided to switch to having our wind sensor connected to an arduino uno that is connected to a Raspberry Pi that will send messages to the pixhawk through a telemetry port as of now we are just trying to display it on the ground station, in the corner. Would you happen to know what code I can look at?
    Nick Nothom
    @NickNothom

    Without knowing more about your setup I can't provide a specific code example. But if that's how you want to do it, running Mavproxy and then using a python script to send messages is probably a good way to do it.

    You could check out this code which takes in data from our Ping sonar and sends it to the pixhawk over Mavproxy. There are probably simpler examples out there though.

    Can someone could help me with a hopefully simple question? I am working with a team that is running an ardusub pixhawk, and we would like to use ALT_HOLD mode. I can't find anything about how to select the pressure sensor used in ALT_HOLD mode. I am hoping that the external pressure sensor is used, which is attached by I2C and shows up as 'SCALED_PRESSURE2'. This is really the only sensor that makes sense for a submarine, so I hope this is the default, but I was hoping to check with experts and save some headache. Thanks for any help!
    Patrick José Pereira
    @patrickelectric
    @nedlrichards yes, the external sensor is the default one, the internal barometer of the pixhawk is not used in ArduSub

    @patrickelectric Thank you very much!

    Hello everyone, completely new and just getting started to setup ardusub, I wanted to verify before I purchase things that is a RPi3 B still required and not a 3B+ or even 4B? Making sure before I puchase.
    Willian Galvani
    @Williangalvani
    Hello, only 3B works out-of-the-box. The current image does not support the new boards yet.
    Willian Galvani
    @Williangalvani
    For the newer boards, you can try to install it from scratch, but some dependencies will break and some tinkering will be required due to hardware (and possibly software) changes.

    I have a ROV with a Raspberry Pi and a Pixhawk running ardusub. I connect to a windows 10 tablet thru a 50m utp cable. problem here is that i have a lot of artifacts on the Video i receive from the rov. Is it better to replace the ethernet cable with a ethernet to RS485 convertor and then convert it back to ethernet. Wil i still get those artifacts ? Is the Lag not going to give a problem ?
    Willian Galvani
    @Williangalvani
    Have you tried shorter/different cables?
    Marnix Verschraegen
    @Max2206_gitlab
    I have those problems also with a 20m cable already. Using a small cable (max 5m) has no problems
    Willian Galvani
    @Williangalvani
    I don't think RS485 has bandwidth for the video
    It is odd that you are experiencing issues with that cable length
    Marnix Verschraegen
    @Max2206_gitlab
    i'm using Cat5e cable of course i could use cat6e or cat7e cable but then the cable isn't that flexible
    Willian Galvani
    @Williangalvani
    I would try, at least to check if the problem goes away
    Marnix Verschraegen
    @Max2206_gitlab
    so try-out different cabels
    Willian Galvani
    @Williangalvani
    I would also experiment putting a router/switch in the way, but I'm just guessing. Let's wait and see if someone has a better solution
