Struct Keyboard

Source
pub struct Keyboard<const COLS: usize, const ROWS: usize, M: MatrixScanner<COLS, ROWS>> {
    pub matrix: M,
    pub debouncer: Debouncer<PressedKeys<COLS, ROWS>>,
}
Expand description

The keyboard “frontend”, manages the keyboard from the hardware matrix through to keyboard events (presses/releases of coordinates on a keyboard layout).

This takes care of scanning the keyboard matrix, debouncing.
