Detailed Description

ESP32 implementation of GPIO input with interrupt support.

Features:

• Internal pull-up resistor enabled
• Interrupt on both edges (rising and falling)
• IRAM-safe interrupt handler
• Software debouncing for buttons

Constructor & Destructor Documentation

EspGpioInput() [1/2]

EspGpioInput::EspGpioInput ( gpio_num_t  pin, uint32_t  debounceMs = 0  )

explicit

Construct ESP32 GPIO input.

Parameters

pin	GPIO pin number
debounceMs	Debounce time in milliseconds (0 = no debouncing)

~EspGpioInput()

EspGpioInput::~EspGpioInput ( )

override

EspGpioInput() [2/2]

EspGpioInput::EspGpioInput ( const EspGpioInput &  )

delete

Member Function Documentation

disableInterrupt()

void EspGpioInput::disableInterrupt ( )

overridevirtual

Disable interrupt for this GPIO.

Implements IGpioInput.

enableInterrupt()

void EspGpioInput::enableInterrupt ( )

overridevirtual

Enable interrupt for this GPIO.

Implements IGpioInput.

getLevel()

bool EspGpioInput::getLevel ( ) const

overridevirtual

Get current logic level of GPIO input.

Returns

true if HIGH, false if LOW

Implements IGpioInput.

operator=()

EspGpioInput & EspGpioInput::operator= ( const EspGpioInput &  )

delete

setInterruptHandler()

void EspGpioInput::setInterruptHandler ( std::function< void(bool level)>  handler )

overridevirtual

Set interrupt handler callback.

Parameters

handler

Function called when interrupt triggers (parameter: current level)

Implements IGpioInput.

simulateInterrupt()

void EspGpioInput::simulateInterrupt

(

bool

level

)

Simulate an interrupt for testing purposes.

Directly calls the interrupt handler with the given level, bypassing actual GPIO hardware. Useful for Wokwi tests where direct GPIO manipulation doesn't trigger ISR.

Parameters

level

The level to report (true=HIGH, false=LOW)
