Member Function Documentation

template<uint8_t PinNumber>

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

inline

set pin configuration

Parameters

[in]	mode	If true set output mode else input mode
[in]	level	If mode is output, set level high/low. If mode is input, enable or disable the pin's 20K pull-up.

template<uint8_t PinNumber>

void DigitalPin< PinNumber >::high ( )

inline

Set pin level high if output mode or enable 20K pull-up if input mode.

template<uint8_t PinNumber>

void DigitalPin< PinNumber >::low ( )

inline

Set pin level low if output mode or disable 20K pull-up if input mode.

template<uint8_t PinNumber>

void DigitalPin< PinNumber >::mode ( bool  pinMode )

inline

Set pin mode

Parameters

[in]

pinMode

if true set output mode else input mode.

mode() does not enable or disable the 20K pull-up for input mode.

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 pull-up.

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.
