Detailed Description

Host-only virtual GPIO driver — no hardware dependency.

Useful for unit tests and simulation. Does not link against any Arduino headers, making it safe to build with a plain C++ toolchain.

Member Typedef Documentation

MapFn

typedef uint16_t(* DirectGPIODriver::MapFn) (uint8_t r, uint8_t c)

Function pointer type: (row, col) → pin index.

Constructor & Destructor Documentation

DirectGPIODriver()

DirectGPIODriver::DirectGPIODriver	(	uint16_t	nPins,
		MapFn	map
	)

Construct with a virtual pin count and a node-to-pin mapper.

Parameters

[in]	nPins	Total number of virtual pins to allocate (heap).
[in]	map	Mapper function; must return indices in [0, nPins).

~DirectGPIODriver()

DirectGPIODriver::~DirectGPIODriver

(

)

Destructor — frees the virtual pin array.

Member Function Documentation

begin()

void DirectGPIODriver::begin ( )

overridevirtual

Zero all virtual pins.

Implements XPointDriver.

commitPhysicalUpdates()

void DirectGPIODriver::commitPhysicalUpdates ( )

overridevirtual

No-op for this virtual driver (writes are immediate).

Reimplemented from XPointDriver.

pinCount()

uint16_t DirectGPIODriver::pinCount ( ) const

inline

Return the total virtual pin count.

Returns

Number of pins allocated at construction.

pinState()

bool DirectGPIODriver::pinState

(

uint16_t

idx

)

const

Read the logical state of virtual pin idx.

Parameters

[in]

idx

Pin index in [0, pinCount).

Returns

true if the pin is HIGH, false if LOW or out of range.

setNodeHardware()

void DirectGPIODriver::setNodeHardware ( uint8_t  r, uint8_t  c, bool  state  )

overridevirtual

Set the virtual pin for node (r, c) to state.

Parameters

[in]	r	Row index.
[in]	c	Column index.
[in]	state	true = pin HIGH, false = pin LOW.

Implements XPointDriver.
