I want to use a gimble which accepts control commands (Not MAVLink commands) on a serial port. Is there any way I can use Pixhawk’s Telem2 port to send these commands from GCS?
I am aware that I can get it done with PWM to serial conversion but I don’t want to use it.

Hi.
I am using latest ArduPlane firmware with my Omnibus F4 Pro V2.
I also bought 2 of SUNNYSKY X2216 KV1100.
I saw many posts in the forum about bad communication between FC and ESC and also timing issues between motors and escs.
I selected 2x Turnigy Plush 30A escs for my plane but not sure whether they play nicely with pixhawk.
Does anybody use these escs?
Do they work good with pixhawk?
Any other low cost ESCs suggestions that provides at least 30A @ 4S will be very appreciated.
Thanks…

I have flown some quads and have been a tinkerer builder for awhile now. I have been slowly 3dprinting parts for a decent sized quad. However, before I go that far and have a big build with expensive parts and what not on a home build quad, I would like to start getting my feet wet with arducopter. So I am curious if anyone has taken some cheap off the shelf quads and basically ripped the guts out and use ardupilot with them. I have 2 quads at home that I would be willing to sacrifice to learning. I have a couple of radio receivers and a FlySky FS-TH9X-B to use.
Thanks for any help getting started!

Hello,
I’m a beginner. I have a boat project that needs to route itself. Yet the project is not only about the boat rovering, it will collect some data too. As the name suggests does the ardu project work on Arduino ?
Is there a software UI for windows? Can I run the project with sonar sensors to avoid collisions?
Is there a complete beginner guide? Can I work on Python? Will the Arduino Mega or Rasperry pi 3 be enough provided with GPS, gyro, compass sensors and 4G or wifi modules?
I want to buy a reasonable priced self righting RC boat and hack it… My aim is not to reach top speeds, but to cover an area and return back without drifting away.

Hi all,
I’ve installed a Mauch 100A current sensor in my drone, as well as a FrSky voltage sensor that runs off the balance lead of the 4s battery I am using. Curiously I am only getting power data from the #2 Power Input port on the Pixhawk board. I’ve historically only used the #1 Power input port, and have always been getting ‘check baord voltage’ warnings when trying to arm, and no voltage or current readings.
After battling with this, I tried the #2 Power Input and now get some data.
First question:
Regarding the voltage calibration. I used the V divider and A/V as supplied by Much, but this resulted in both mV and mA readings, which aren’t correct. I then followed Randy’s video online (https://www.youtube.com/watch?v=tEA0Or-1n18) and, using the measured voltage from the FrSky monitor, got a different V divider, and very spiky inconsistent voltage data on the dashboard and through the status telemetry:The battery voltage is a consistent 15.86V, yet the Pixhawk telemetry is all over the place.
Second question:
I also checked the board voltage and the servo voltage, but I have no idea what these should be. 5V for the servo seems good. but perhaps the board voltage should be higher than 4V?Third question:
Regarding the current sensor - I don’t yet have a Power analyzer to check the current - which prevents me from completing the current calibration. But it is strange that when I use the values for V div and A/V supplied by Mauch, the values are so low.Any advice would be greatly appreciated!!
Chris.

Hi, it something was done to mavlink messaging since mid-december, it seems
I am asking here as well, as it is not likely anything Chibios related.I just pulled in new master, then recompiled code, as usual, flashed it, and then during test i saw that all mavlink messages are gone in the OSD. everything works, all other OSD output is there, the only missing item was the content usually shown in the ‘OSD_MESSAGE_EN’ field. like, what it writes if refuses to arm, ‘SIMPLE MODE OFF’ or ‘SIMPLE MODE ON’ etc. messages.
i then flashed back code from 12/03 - and messages were back. then i flashed back new code - and saw messages again in the OSD, at that point i concluded it was my error, so went outside to test, and OSD has no messages again. it seems, now, that if i boot model from USB cord and connect to MP, then connect lipo to activate power and VTX - messages do work in OSD. if model is powered from lipo directly - then OSD does not show them. with 12/03 code it does not matter - it shows any message in any way - starting with cord or not.
it is on nano v6 FC - it has no sd card and no logging, not sure if it matters. does anybody know anything about this issue or can replicate? i do not know what exactly triggers it and on nano v6 there is nothing really that can help to troubleshoot it.

Reading about the Ardusoar addition to Arduplane, I mentioned it to a glider flyer mate. He jokingly said could I send my electric glider to the flying field about 3 miles distant and have it land there waiting for me to get there. This got me thinking.
Would it legal to set up a mission which would have the glider launched from somewhere near home, with a flight plan to fly adjacent to the road, and rtl at a rally point at the flying field. The plan would be to follow the glider in my mate’s car, keeping it in sight at all times.
Would it be legal?

Hey all,
Last week I was out flying my quadcopter for a group of co workers, the flights were going pretty smoothly for about two hours or so (flying around our front office building with a joystick setup)
But for whatever reason,near the end of my last flight, the quad developed an EKF error and was switching back and forth between EKF0 and EKF1? It also wouldn’t hold altitude any longer even though it was in Loiter mode.
I am using a LightWare SF11/c for altitude hold, I assumed that it would fall back to the baro to hold alt. if it experienced an error, but didn’t seem to be the case in this situation. I also have a PX4 flow sensor on the bird but I don’t believe it was enabled at the time, I was using GPS for position hold.
I am unsure if this was a “sticky i2c bus” that I have heard about or if it was some other issue that caused it to act somewhat erratically.
Luckily there were no crashes or anything and I was able to land, but I want to know what caused it and how to prevent it again in the future.
I’m going to include a dropbox link to the log that I am pretty certain was the log from that flight as it is the only one that had an EKF error in it.
Thanks!

Okay, facing doing some long missions and am concerned about baro drift, which we have seen in the past but are of larger concern with these longer flights.
It seems that it would be easy, and consistent with manned aviation, to tie the GND_ABS_PRESS or GND_ALT_OFFSET to an altimeter setting, so that over the course of a long flight or over long distance, you could compensate for drift by getting an updated altimeter setting. Possibly, even doing so automatically using the aircraft’s location to pull data from the nearest wx station within a user defined radius.
thoughts?

I have just connected the ADS-B receiver to the Pixhawk, connected the pixhawk to my PC and started mission planner.
All is working fine. I can see the airplanes and when I mouse over the airplane I can see an ICAO number.
But I don’t see any other information like altitude, heading and speed.
Is it supposed to be like that or should I see those details as well. If yes, how to enable this view?

Hello everyone and Merry Christmas in advance! This year I have prepared to mount a RPLIDAR A1 2D 360 on my drone, and I have the following question.
I have been seeing the information about it and the video of our partner @rmackay9 and there is something that I have not understood and I would like you to clarify it to me.
I thought that this sensor can replace the GPS for indoor flights, my idea was to use this sensor together with a lidar to control the altitude and thus make a decent indoor flight, but according to the wiki is only to detect possible obstacles. Is this really like this? Or can it also be used as a GPS spice so that our drone maintains the position in loiter?
I appreciate any help in this regard, or contact someone who can help me clarify this or carry it out.

Hi,
In FBWA when approaching to land I cut the throttle but the motor keep running in idle until touched the ground.
Right after the landing and in the same mode (FBWA) I apply throttle and then cut and the motor stop.
Any one can help with this.
The plane is a Skywalker X8 and I’m running the latest firmware in a Pixhawk 2 Cube with folding prop.
Thanks

Stock GPS recomenndedWill i need an external GPS and what other modules are essential?
Are there cheap Sonar alternatives?(there are lot cheaper sensors for sonar)
also GPS and compass list is very pricey?or should i stritcly choose one amongst them?
can you help me on this regard.
it will have a camera connected to the Rasperry . Rasperry will have internet connection too.
Will it help me budget wise?will i need an external RC transmitter for the boat?
If possible i would like to go with the sufficient compass gps and sonar sensor.
I will also have a 2 axis gimball with 2 servos connecting to pixhawk
this gps şs 1hz and 5v
will it work? can you help me a bit on the alternative sensors :))

I really need to order them ASAP and start working because ı know this project will be definetly very hard for me.
I will also have a 2 axis gimball with 2 servos connecting to pixhawk to stabilize the Camera(I want to install it in 90’ angled position to make it roll and tilt not tilt and pan if possible tho)
this gps şs 1hz and 5v (will it gonna work seamlessly?)
Will this sonar work efortlessly with ardurover?(it is very cheap for collusion avoidance)
I really need to select my components and order them to start the project.
any help is very appreciated.
