@jberaud @rmackay9 I'm trying to revive the support for bebop 1 on ardupilot (because I don't want to risk my disco for some changes on Skycontroller 2). RC is working for bebop now. I also "fixed" the issue of having to statically build arducopter: I can now use libiio and other libs - I'm bundling them.

@jberaud @rmackay9 after checking https://ardupilot.org/dev/docs/building-for-bebop-on-linux.html it seems it's a bit outdated... and after the step "Upload the update file bebopdrone_update.plf", the original flight stack started to flip on takeoff and gps is failing (not sure if it wasn't failing before). With arducopter, trying a " bench takeoff " (i.e. holding it with my hands) it seems the drone would equally flip

@jberaud @rmackay9 any idea what would cause that? motor order appears to be correct and with the right direction (it's harder to check since bebop doesn't support turning one motor at a time)

Anyone know how to set servos using MavProxy?

I've got sequence of servo actions I'd like to perform just via command line before I test them on a waypoint mission

RickReeser

@RickReeser

servo set x yyyy, where x is the servo number and yyyy is pwm value

Ben

@bendespain

ah, yes, thanks, I guess I had a hardware issue. Thanks!
This worked for me:

mavproxy --master com7
servo set 9 2200

@RickReeser is there a similar command for MavROS?

Hello, I just started making quadcopter. I am using Pixhawk card and I want to load code into it. On which platform should I do this? I will be happy if you inform me.

hi, any suggestions on the best combination of setting up a development and simulation/test environment on mac OS X - i think the build environment setup given on the dev page is fine, any other combination based on experience ? Also not using vagrant

@jberaud

@lucasdemarchi Hi. The "building for bebop on linux" should now be totally rewritten. I should mostly match what's for the bebop2, but I'll need to get back to my bebop1 hardware. The flip problem could come from the differences in motor orders between bebop1 and bebop2 if some things have been inverted...

@PRIMETSS

Anyone know why SR3 (is this usb port?) seems to reset back to 2Hz after saving para, then re-opening MissionPlanner. Other SR#'s stay as set.
Anyone know what SR#'s relate to for PIXHawk4? Cant find a list anywhere

Lucas De Marchi

@lucasdemarchi

@jberaud thanks. I will double check the ordering, but on a first check it appears to be correct. Note that it flipped with the original flight stack... So I think if it may not be possible that the .plf update changed the bldc firmware

Hello all, I am a novice in Dronekit. I have learnt the arducopter very well but I want to work on a fixed wing plane. When I run the following commands,
dronekit-sitl plane (terminal 1)
mavproxy.py --master tcp:127.0.0.1:5760 --out 127.0.0:14550 --out 127.0.0.1:14551 --map --console(terminal 2)
I get this message in terminal 2 -" no link
link 1 down
no link"
Will be happy if anybody is able to help me

Hi, i'm new in this but, I borrowed from a friend a drone that have ardupilot 2.5 (my friend can't help me because he doesn't know to code) and i want to make an university licence and i need to know everything i do at this drone, how it works, mathematics, from where i should start? Any turoriat to learn and be able to understand it good.

has anyone tested the SITL sim_vehicle.py with python3 and OS X

i get the error - /ArduPilot/modules/waf/waflib/Task.py", line 338, in process ….. ImportError: No module named future

i run sim_vehicle with python3 and future is installed

Jaaaky

@Jaaaky

Does mavproxy have MAV_CMD_FIXED_MAG_CAL_YAW implemented as command? Which GCS has this implemented if any?

@andyp1per

@tridge any chance ArduPilot/ardupilot#13169 can be merged?

@gauthampkrishnan

Hello everyone I am new to this channel :) I need to contribute to the Ardupilot repo

Lucas De Marchi

@lucasdemarchi

@harshitsankhla you need python3-future

Jaaaky

@Jaaaky

@gauthampkrishnan Read as much as possible on ardupilot dev wiki first, read contributing guide, fork, clone, try to understand code structure, review the code of vehicle and some random libs, create new branch, have an idea try to apply it, follow the same coding style - try to mimic how such thing is done on other parts of code, test on SITL and real boards, commit, git push your changes to your fork, send a link here about your changes and idea behind them, if interesting, send a pull request. Be patient :)

Also learncpp and a bit of python too is not bad.

Harshit Kumar Sankhla

@harshitsankhla

@lucasdemarchi future is installed for python3, I think the problem is different, when I run the script it detects my python2 version

by script I mean sim_vehicle.py

is there a way to change python version to python3 here ?

running the script with python3 suffix is also not working

Jaaaky

@Jaaaky

@harshitsankhla Open sim_vehicle.py and change the command on 1st line to python3

Harshit Kumar Sankhla

@harshitsankhla

nope, thats not fixing it

i think it has something to do with the pythonpath being fetche

Lucas De Marchi

@lucasdemarchi

@harshitsankhla install the python2's version of future or ensure you are loading the script with python3... e.g. by calling it like (python3 /path/to/sim_vehicle.py) or by ensuring python points to python3 rather than python2 in your distro

Harshit Kumar Sankhla

@harshitsankhla

I am loading the script with python3 as you’ve mentioned. Is this because MAVProxy is not supported for python3 ?

Jaaaky

@Jaaaky

It's

Harshit Kumar Sankhla

@harshitsankhla

resolved using - ln -s -f /usr/local/bin/python3 /usr/local/bin/python
thanks @lucasdemarchi

Hello everyone I was trying to bypass mavproxy , instructions are given in the ardupilot.org . The problem is that I am unable to find ./ArduCopter.elf file . When I run command # ./ArduCopter.elf --home -35,149,584,270 --model quad from ArdupilotCopter directory terminal gives an error saying ./Ardupilot.elf no such directory or file. Can anyone help me ?

auturgy

@auturgy

@prajwal210798 look in the build directory

prajwal210798

@prajwal210798

@auturgy I checked build directory by searching ArduCopter.elf , didnt find any file.
Is the issue is related with the running of sim_vehicle.py ? Thank you for your reply

auturgy

@auturgy

Have you compiled the sitl binary? From the top ArduPilot directory,
./waf configure —board sitl
./waf copter
then you’ll find the elf in the build/sitl directory

@andyp1per

did anything change in memory allocation recently in master? My code is no longer able to allocate fairly trivial amounts of memory it seems. Probably my bug, but just wondering

it's just me, never mind :-P
