I just start building a quadcopter recently. I am planning to put raspberry pi and APM 2.5 on the quadcopter.
The raspberry pi could take picture and send images through wireless network. in addition, the raspberry pi is connecting to the APM 2,5 using USB, Just wondering if there is any way I can retrieve information from APM 2.5 via the USB. For example, pitch, roll, yaw, and altitude. When raspberry pi gets these data, it can forward them to the remote machine.
