RMK's input device system is a unified, event-driven framework designed to support diverse input devices.
Input devices are hardware peripherals beyond the standard key matrix, such as rotary encoders, joysticks, etc. Input devices provide additional input or sensing capabilities, enabling more possibilities of human-machine interactions.
