I am building a quadcopter and plan to use an old flight controller that is no longer supported: APM 2.8. It needs to connect to an app called Mission Planner which is used to install the flight firmware, configure the controller, plan waypoint missions and track the aircraft via a telemetry modem. Anyway, in order to connect to the controller, I must select a COM port from a list displayed via Device Manager. My problem is that I cannot access any such list on Windows 10/11.
I received a suggestion that if I install Arduino, it will install the usb drivers for the Atlega chip that the APM uses and so it will show up as a COM port. I'm just throwing this out to the ether - can anyone tell me if this will work?
I moved your topic to an appropriate forum category @fossilrider.
In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.
That's only if the APM does use one of the chips that is used in the Arduino environment.
Your best bet is to check in Windows device manager what happens when you connect the board; yellow exclamation marks, unknown device, .... If there is something in Windows device manager, you can find the vid/pid of the board and based on that start looking for the driver.
Note
It's not clear to me if Windows device manager does not give you a list of ports or that your Mission Planner app does not give you ports.
