2 years ago yeah, maybe the build instructions should be more extensive.
For building python ros packages, you need to make the python script an executable, using chmod +x dji_rs2_ros_controller/scripts/can_bus_controller.py
Then build using catkin build dji_rs2_ros_controller.
Then source your workspace using source devel/setup.bash.
Let me know if that works.

2 years ago checked mutliple, src, devel, build, ones before and after compiling, same error I'm running this for testing purposes without a connection to the actual H/L/GND pins right now. that shouldn't make a difference?

2 years ago What is in your catkin_ws/src folder? there you should have the this package. and within this package in the scripts folder you need to make the python script executable with chmod +x can_bus_controller.py.
Don't adjust anything in the catkin_ws/devel oder catkin_ws/build directories, only in catkin_ws/src. You can do catkin clean to reset them.
Then you can build the package, then you can source it using source ~/catkin_ws/devel/setup.bash

2 years ago have been able to run ros examples and bag recording/playback
too many levels down? i used the git clone on the readme
inside catkin_ws/src
-dji_rs2_ros_controller -----dependencies -----dji_rs2_ros_controller -----readme.md
- CMakeLists.txt
it builds but says 5 skipped followed all instructions to the T, same error over and over have changed permissions. reinstalled, re-imaged, etc.

fx@fx-VirtualBox:~/catkin_ws/src$ `what version of linux and ros distro was this using? seems melodic on 18.04?

2 years ago From that log it seems to build fine. I think back then I programmed it on 18 with melodic, but it's also working fine on my 20/focal.
From your previous log file it seems like it has issues to import the service definitions from the srv directory. I don't really know what the issue is there, maybe because you have two directories called dji_rs2_ros_controller within each other (one from the git repo, one from the ros package). Maybe try renaming the top level one of those two, then do catkin clean, catkin build and source the workspace again. Let me know if this works.

2 years ago it does not, even when moving things around and removing top level. again it shouldnt be a problem to launch that I dont have pins connected right now?

`No, having the gimbal not connected shouldn't be an issue.
It's still some issue with importing the ROS service definition into the main script.
Can you type rossrv list in your terminal. It should return a long list of standard services, and somewhere in between should be the two dji_rs2 services. if they're not there, then something is going wrong in building the package.

maybe try adding an empty file called __init__.py to the scripts directory. Then clean, re-build, re-source.

2 years ago Resolved I think it has to do with following a guide that installs a 2nd catkin instead of the native being used from the ros install. that was a headspin. Im going to see how it goes with ros bags now. phew! thanks
after building have an error on line 12/15 what did i do wrong?
