Struct DuplexMatrixScanner

pub struct DuplexMatrixScanner<F: FlexPin, T: Fn(ScanDir, usize, usize) -> Option<(usize, usize)>, const ROW_PIN_COUNT: usize, const COL_PIN_COUNT: usize, const ROWS: usize, const COLS: usize> { /* private fields */ }

Implementation of keyscan driver for duplex matrix.

Implementations

impl<F: FlexPin, T: Fn(ScanDir, usize, usize) -> Option<(usize, usize)>, const ROW_PIN_COUNT: usize, const COL_PIN_COUNT: usize, const ROWS: usize, const COLS: usize> DuplexMatrixScanner<F, T, ROW_PIN_COUNT, COL_PIN_COUNT, ROWS, COLS>

pub fn new( rows: [F; ROW_PIN_COUNT], cols: [F; COL_PIN_COUNT], output_wait: Option<OutputWait>, translate_key_position: T, ) -> Self

Detect the hand and initialize the scanner.

Arguments

• rows: Row pins of the matrix.
• cols: Column pins of the matrix.
• output_awaitable: Whether the output pins can be awaited for high/low. For more detail, see OutputWait. Default: Time(20us)
• left_detect_key: The (logical, not pin index) key position to detect the hand.
• translate_key_position: Function to translate key position from pin number and scan direction to key (scan direction, row, col) -> Option<(row, col)>

async fn scan(&mut self, cb: impl FnMut(KeyChangeEvent))

Scans a key and returns the delta from the previous key scan
