Press the buttons and arrows to retrieve the codes. Here is the # 2 on the device /dev/input/event2 . The script asks you which device to listen to. The evdev library comes with a script that decodes the input device codes connected to the Linux PC or Raspberry Pi. Here, we can recover the Gamepad actions on the event2.

Now connect the Gamepad (or a joystick) and run the command again to identify the port. Run the ls / dev / input command a first time # ls /dev/input/ Input devices (keyboard, mouse) as well as joysticks, gamepads and joysticks are input devices under Linux.

That’s it, it remains only to update the system to have the latest versions of the libraries sudo apt-get update & apt-get upgrade -y Identify the USB port to which the Gamepad or joystick is connected
USB JOYSTICK CONTROLLER CARD LINUX INSTALL
Then python-dev and the evdev librarie sudo apt-get install python-pip If pip is not installed, run this command sudo apt-get install python-pip Now check that the pip package for easily installing libraries is installed #pip -version To make sure, open a Terminal and run the following command #python -version Python 2.7 is installed by default on the Raspbian distribution. Install python and the evdev library on Raspbian for Raspberry Pi 3 On the other hand, as it exploits Linux kernel events, it is not available on Windows or macOS. We can develop projects on Raspberry Pi 3 (or RPIZero) or a Linux PC (Ubuntu for example). The Python evdev library works on Linux systems.
USB JOYSTICK CONTROLLER CARD LINUX HOW TO
In this article we will learn how to decode the codes of an analog Gamepad compatible with Nintendo consoles that are very commonly found for less than $2.5 / €2 on AliExpress. We can for example use a gamepad in a game project or drive the servomotors of a robotic arm as the ROT2U 6DOF presented in this article. The Python evdev library makes it possible to decode the codes sent by the input devices (keyboard, mouse, analog joystick, gamepad …) to exploit them in any project.
