Emulate joystick input via numeric input I have an arduino which gives me numbers from a potentiometer (300-600), device /dev/ttyACM0 baudrate 9600. I want to use these numbers as a 1-axis joystick. My system is archlinux and X-Displaymanager.

I've done it with python and uinput:


#!/bin/env python2

import serial
import time
import uinput
ser = serial.Serial('/dev/ttyACM0', 9600)
events = (uinput.BTN_JOYSTICK, uinput.ABS_X + (0, 255, 0, 0))
device = uinput.Device(events)
device.emit(uinput.ABS_X, 128, syn=False)
while True:
value = ser.readline()
valuecorrect = value.strip()
valuecorrect = int(valuecorrect)/4
print valuecorrect
device.emit(uinput.ABS_X, int(valuecorrect))


For the calibration I use jstest-gtk.
