Macros
#define	LOW 0x0
	Represents a low state (0V).

#define	HIGH 0x1
	Represents a high state (usually 3.3V or 5V).

#define	CHANGE 0x2
	Represents a change in state.

#define	FALLING 0x3
	Represents a transition from high to low.

#define	RISING 0x4
	Represents a transition from low to high.

Functions
void	interrupts (void)
	Enables interrupts, allowing the execution of interrupt service routines. More...

void	noInterrupts (void)
	Disables interrupts, preventing the execution of interrupt service routines. More...

uint8_t	digitalPinToInterrupt (uint8_t pin)
	Converts a digital pin number to the corresponding interrupt number. More...

void	attachInterrupt (uint8_t interruptNum, void(*userFunc)(void), int mode)
	Attaches an interrupt service routine to a specified interrupt. More...

void	detachInterrupt (uint8_t interruptNum)
	Detaches an interrupt service routine from a specified interrupt. More...

Detailed Description

Interrupt-related functions and definitions.

Function Documentation

Attaches an interrupt service routine to a specified interrupt.

Parameters

interruptNum	The interrupt number to attach the ISR to.
userFunc	The function to call when the interrupt occurs.
mode	The type of interrupt to attach the ISR to (e.g., CHANGE, FALLING, RISING).
