Detailed Description

A debounced reading from a Gpio.

Constructor & Destructor Documentation

GpioDebounce()

GpioDebounce::GpioDebounce	(	unsigned int	interval,
		unsigned int	channel )

Same as setup(), but throws on error.

Member Function Documentation

setup()

int GpioDebounce::setup	(	unsigned int	interval,
		unsigned int	channel )

Set up the Gpio and debouncer.

Parameters

debounce	the number of calls to process() during which changes are ignored after a change in the input vaulue has been detected.
channel	the GPIO channel, as passed to Gpio::open()

Returns

0 on success or an error code otherwise.
