Hello Guys I am new here
I am trying to work on the issue #15461 Emit log message and statustext when an InternalError occurs. Can anyone guide me on this . :)
Does anyone have any experience with real-time geotagging images from a companion computer?
@adezie yes I made it before that mission.
@Schouten_B_twitter yes ,it seems that,but swithing imu will cause crashing ,I ve try it before.
I found a huge consumption of power if tuned badly,which will shorten the flying time in the air .

Hi everyone I am new here.
I try to figure out how to see other aircraft adsb data from my aircraft. We try to test our collision avoidance algorithm, so we use a quadcopter with the ADS-B as other aircraft. Our aircraft should avoid the quadcopter when it's too close. However, when I try to print out the GPS data for the quadcopter, it's way off like on the other side of the earth. So I wonder how can I receive and see the adsb or GPS data of the quadcopter.

Hi. I'm looking to add some control and navigation algorithms to Ardupilot. Is there any guide for that? If someone has done this before, can they contact with me? Thanks

PingRX does not transmit ADSB data
Hey, How can I add custom C programm or script run on boot ?
Can I use Eclipse with WSL on Windows 10? Not enamored with Cygwin64 with Eclipse. I could not see a guide to this.
image.png Above seems to be where I am having an issue setting up Ardupilot to compile with waf within Eclipse -- pointing it to python2.7 No issues with doing in in a bash session. Does Eclipse work with WSL?
Or more specifically can you compile through Eclipse on WSL?

I'm looking for ways to access cpu temperature and load. Has this been looked into before? Or are there any plans to implement the mavlink message onboard_computer_status (390)?
Hi everyone, I connected analogue Ph sensor to pixhawk1 6.6v adc, I want to get data from it. On my pixhawk I use nuttxOS with ardusub v3.5.4, I didn't found message for asking Raw data with pymavlink.
it seems that P is more bigger,it's Z axis tune.
Hey I'm trying to get a tilt mask set up for a tilt rotor tricopter. What's the tilt tricopter when all three tilt? We haven't been able to make sense of it
I guessed 7, but my back motor isn't spinning
We have the left and right motors set to motors 1 and 2. The back set to motor 4
I got it... 11
Any one tried to control brushless gimbal using ESC using pixhawk directly?
Any code to do so?
Anybody tried to simulate LibNPNT Firmware (https://github.com/bugobliterator/ardupilot/tree/pr-libnpnt)?

Hi! I am trying to run sim_vehicle.py on Copter-3.5.2, But getting this as error :
/usr/include/x86_64-linux-gnu/bits/string_fortified.h:34:33: error: ‘void* __builtin_memcpy(void*, const void*, long unsigned int)’ forming offset [11, 16] is out of the bounds [0, 10] [-Werror=array-bounds]
And I get a warning :
WARNING: Unable to load XML validator libraries. XML validation will not be performed
Is the above error caused by due to this particular warning ? And any tips on how to tackle this?

the error is coming from :

Any suggestions ? I have been on this for last 2 days but couldnt figure out the issue.
What is the difference between an AP_Param::GroupInfo and an AP_Param::Info? I.e. why have both of these data structures? Is one a legacy from an early version of AP?

Hello everbody, I was running ArduCopter sitl and dronekit for my project. I could able to send condition yaw and set position target for x,y,z velocities. But when I change to ArduPlane fixed wing these commands are not working any more I'm getting COMMAND_ACK: CONDITION_YAW: UNSUPPORTED for MAV_CMD_CONDITION_YAWmessage and when I try to send set_position_target_local_ned_encodemessage for pitch or else I don't get any error except COMMAND ACK: DO_CHANGE_SPEED: ACCEPTED for my pre-defined change speed function in this case my speed is not changing. Lookslike everthing is running differen in ArduPlane SITL. Also I was reading dronekit and ardupilot wikis' but I couldn't find commands/messages that sorts my request. What should I do :/

What is the difference between MAV_CMD_ACK and MAV_RESULT. I have a result id of 4, but I don't know it is UNSUPPORTED or FAILURE.
eNTi hi
eNTi anyone else seen some sudo weirdness today?
eNTi my password is no longer accepted
eNTi to be more precise: sudo <command> still works, but sudo su doesn't
