This program translates keyboard events to joystick events! It was made with the main purpose of emulating joystick movement with the mouse.
Clone the repository and execute the program using cargo. The user needs to be in the "input" group; otherwise, it will be necessary to run the program as root. It is also necessary for the uinput module to be activated.
sudo modprobe uinput
cargo run --releaseThe program uses an environment variable called "GAMEPAD_PROFILES". Its configuration file must be called "virtualconf.json". Below is an example of configuration:
{
"mouse" : "/dev/input/event7",
"keyboard" : "/dev/input/event6",
"events" : {
"REL_X": "10000|+|ABS_X",
"REL_Y": "10000|+|ABS_Y",
"BTN_LEFT": "1|+|BTN_WEST",
"BTN_RIGHT": "1|+|BTN_TR",
"KEY_W": "100000|-|ABS_RY",
"KEY_A": "100000|-|ABS_RX",
"KEY_S": "100000|+|ABS_RY",
"KEY_D": "100000|+|ABS_RX",
"KEY_F": "1|+|BTN_SOUTH",
"KEY_Q": "1|+|BTN_MODE",
"KEY_SPACE": "1|+|BTN_NORTH",
"KEY_E": "1|+|BTN_TL",
"KEY_X": "1|+|BTN_THUMBL",
"KEY_LEFTCTRL": "1|+|BTN_THUMBR",
"KEY_LEFTSHIFT": "1|+|BTN_EAST",
"KEY_3": "1|+|BTN_THUMB",
"KEY_R": "1|+|BTN_SELECT",
"KEY_1": "1|+|BTN_START",
"KEY_LEFT": "1|+|BTN_DPAD_LEFT",
"KEY_RIGHT": "1|+|BTN_DPAD_RIGHT",
"KEY_UP": "1|+|BTN_DPAD_UP",
"KEY_DOWN": "1|+|BTN_DPAD_DOWN"
}
}
The file needs to declare mouse, which is the path to your mouse in /dev/input. The same goes for the keyboard. In events, the first value corresponds to the trigger, that is, the mouse/keyboard event. The value associated with the trigger is the Virtual Joystick event, in the following format:
{Value multiplier}|{Multiplication sign}|{Event}
