Functions
void	attachInterrupt (pin_size_t interruptNumber, callback_function_t callback, PinStatus mode)
	Attach a callback function to an external interrupt on a pin.
void	attachInterrupt (pin_size_t interruptNumber, voidFuncPtr callback, PinStatus mode)
	Attach a function to an external interrupt on a pin, using a plain function pointer.
void	detachInterrupt (pin_size_t interruptNumber)
	Disable the external interrupt attached to a pin.

Detailed Description

External interrupt functions: attachInterrupt() and detachInterrupt().

Function Documentation

attachInterrupt() [1/2]

void attachInterrupt	(	pin_size_t	pin,
		callback_function_t	callback,
		PinStatus	mode
	)

Attach a callback function to an external interrupt on a pin.

Note

LOW and HIGH level triggers are only available on series supporting level interrupts, otherwise they fall back to FALLING and RISING respectively.

Parameters

pin	The pin to attach the interrupt to.
callback	Function called when the interrupt fires. It takes no arguments.
mode	Trigger mode: CHANGE, RISING, FALLING, LOW or HIGH.

attachInterrupt() [2/2]

void attachInterrupt	(	pin_size_t	interruptNumber,
		voidFuncPtr	callback,
		PinStatus	mode
	)

Attach a function to an external interrupt on a pin, using a plain function pointer.

Parameters

interruptNumber	Pin to attach the interrupt to.
callback	Function called when the interrupt fires.
mode	Trigger mode: CHANGE, RISING, FALLING, LOW or HIGH.

detachInterrupt()

void detachInterrupt

(

pin_size_t

interruptNumber

)

Disable the external interrupt attached to a pin.

Parameters

interruptNumber

Pin whose interrupt is disabled.
