Public Member Functions
	XPointStatic (RelayType type=RE_NON_LATCHING, uint16_t pdur=0)

Public Member Functions inherited from XPoint
	XPoint (uint8_t rows, uint8_t cols, RelayType type=RE_NON_LATCHING, uint16_t pdur=0)
	Heap-allocating constructor.

	XPoint (uint8_t rows, uint8_t cols, uint32_t *pool, RelayType type=RE_NON_LATCHING, uint16_t pdur=0)
	Zero-heap pool constructor.

	~XPoint ()
	Destructor. Frees pool only when built with the heap constructor.

	XPoint (const XPoint &)=delete

XPoint &	operator= (const XPoint &)=delete

void	setDriver (XPointDriver *drv)
	Attach a driver backend. Must be called before begin().

void	begin ()
	Initialize hardware via drv->begin(). Call once after setDriver().

bool	connect (uint8_t row, uint8_t col)
	Connect row to column.

bool	disconnect (uint8_t row, uint8_t col)
	Disconnect row from column.

bool	setLevel (uint8_t row, uint8_t col, uint16_t level)
	Analog-level connect / disconnect for PWM drivers.

void	clearAll ()
	Disconnect all nodes, zeroing the state section of the pool.

void	lockRows (uint8_t rowA, uint8_t rowB)
	Prevent rowA and rowB from sharing a column simultaneously.

void	exclusiveInput (uint8_t col)
	Mark column col as exclusive: at most one row may connect at a time.

void	update ()
	Expire latching-relay coil pulses and call releaseNode() as needed.

Detailed Description

template<uint8_t ROWS, uint8_t COLS>
class XPointStatic< ROWS, COLS >

Zero-heap XPoint with a compile-time-sized embedded bit pool.

Declare as a global or static local to keep everything in BSS/data.

XPointStatic<4, 4> matrix(RE_NON_LATCHING);
matrix.setDriver(&myDriver);
matrix.begin();

Template Parameters

ROWS	Row count (compile-time constant, 1–255).
COLS	Column count (compile-time constant, 1–255).
