Constructor

Member Function Documentation

template<uint8_t PinNumber>

void DigitalPin< PinNumber >::config	(	uint8_t	mode,
		bool	level
	)

inline

Set pin configuration.

Parameters

[in]	mode	INPUT or OUTPUT.
[in]	level	If mode is OUTPUT, set level high/low. If mode is INPUT, enable or disable the pin's 20K pullup.

template<uint8_t PinNumber>

void DigitalPin< PinNumber >::high ( )

inline

Set pin level high if output mode or enable 20K pullup if input mode.

template<uint8_t PinNumber>

void DigitalPin< PinNumber >::low ( )

inline

Set pin level low if output mode or disable 20K pullup if input mode.

template<uint8_t PinNumber>

void DigitalPin< PinNumber >::mode ( uint8_t mode )

inline

Set pin mode.

Parameters

[in] mode INPUT, OUTPUT, or INPUT_PULLUP.

The internal pullup resistors will be enabled if mode is INPUT_PULLUP and disabled if the mode is INPUT.

template<uint8_t PinNumber>

DigitalPin< PinNumber >::operator bool ( ) const

inline

Parenthesis operator.

Returns: Pin's level

template<uint8_t PinNumber>

DigitalPin& DigitalPin< PinNumber >::operator= ( bool value )

inline

Asignment operator.

Parameters

[in] value If true set the pin's level high else set the pin's level low.

Returns: This DigitalPin instance.

template<uint8_t PinNumber>

bool DigitalPin< PinNumber >::read ( ) const

inline

Returns: Pin's level.

template<uint8_t PinNumber>

void DigitalPin< PinNumber >::toggle ( )

inline

Toggle a pin.

If the pin is in output mode toggle the pin's level. If the pin is in input mode toggle the state of the 20K pullup.

template<uint8_t PinNumber>

void DigitalPin< PinNumber >::write ( bool value )

inline

Write the pin's level.

Parameters

[in] value If true set the pin's level high else set the pin's level low.
