I need guidance to build a controller with Raspberry pi
I bought this joystick
Like your system, I want to do this without using Pixhawk
The joystick will be connected to the ground station
The commands are transmitted to Raspberry pi via the network and done something, for example read the joystick information
Our system uses a pixhawk. You can use Navio2 or pxf mini with raspberry pi.
I want to know how to transfer data from joystick to raspberry
There are many ways to do it. Try pyjoy and sockets.
