Why did you do this?
I like playing shooter games on PC but my laptop is too weak to play them. Game consoles do not support USB keyboards and USB mouse, they only support gamepads. Gamepad controls are not suitable for shooter games, using a keyboard and mouse is much more comfortable for gameplay.
How does it work?
I designed a circuit that features a microcontroller and USB hub. The keyboard and mouse plugs into the USB hub, and then the microcontroller takes the data from the keyboard and mouse, translates them to the data format used by the PlayStation 4. It does the translation in a way as though the mouse was the right thumbstick, and the keys are mapped to buttons (the WASD keys are mapped to the left thumbstick).
