@julian I just copied “PX4-Autopilot/src/examples/work_item” folder, and made changes in all 4 files CMakeLists.txt, Kconfig, .hpp and .cpp files and boardconfig.h file also accordingly.
Then executed cmake, and make commands.
What else I need to do ?
What have you tried so far? did you read this in a guide? is there any particular reason you are tagging a developer directly?
No not any reason for tagging. Sorry for that. next time i will take care of it.
