SDL2 joystick driver for python

clamps

Note: I only have playstations, so I don't know if this will work with other joysticks.

This is actually something I did long ago, but finally decided to make it a module available on PyPi.

Setup

This requires sdl2 inorder to work:

brew install sdl2       # macos
apt install libsdl2-dev # linux

This package will install the python bindings PySDL2 from pypi.

Tested:

• Works with joystick connected via USB cable
• Works with joystick connected via bluetooth
• Works with PS4 controller

Example

#!/usr/bin/env python3
import time
from clamps import PS4Joystick

def main():
    import time

    js = PS4Joystick()

    while js.valid:
        try:
            ps4 = js.get()
            print(ps4,"\n----------------------\n")
            time.sleep(0.1)
            if ps4.buttons.pad is True:
                break
        except KeyboardInterrupt:
            print('js exiting ...')
            break


if __name__ == "__main__":
    main()

Output of get() is a namedtuple with the following fields:

JS(info=JSInfo(num_buttons=16, num_axes=6, num_hats=0), leftstick=Axis(x=-0.003936767578125, y=0.011749267578125), rightstick=Axis(x=-0.01177978515625, y=-0.050994873046875), triggers=Axis(x=0.0, y=0.0), buttons=PS4Buttons(x=False, circle=False, square=False, triangle=False, share=False, ps=False, options=False, L3=False, R3=False, L1=False, R1=False, dp_up=False, dp_down=False, dp_left=False, dp_right=False, pad=True))

How to pair a DUALSHOCK 4 wireless controller with a supported device

To pair your wireless controller with a supported device using Bluetooth for the first time, turn on pairing mode.

1. Make sure the player indicator on the controller is off. If the player indicator is on, press and hold the PS button until it turns off. If a USB is connected to the controller, disconnect it.
2. While pressing and holding the SHARE button, press and hold the PS Button until the light bar flashes.
3. Enable Bluetooth on your device, and then select the controller from the list of Bluetooth devices. When pairing is complete, the light bar blinks, and then the player indicator lights up.
