I am currently using Mission Planner with a Pixhawk. As I am new to ardupilot, i just made my first flight mode. It doesn’t do anything, but after adding the appropriate parameters to Mission Planner, It is showing up! However, anything I added to the parameters shows up regardless if code exists for the flight mode. My idea was to have the buzzer beep once it entered the custom flight mode so i know the build on the Pixhawk of the custom flight mode is getting called properly. I can’t seem to find how to interface with the buzzer and make it beep through the new mode code. I’ve looked through AP_Notify but I only have a year’s worth of experience with c++. Any help would be greatly appreciated!
