Member Function Documentation

void mbed::DigitalInOut::input ( )

inline

Set as an input

int mbed::DigitalInOut::is_connected ( )

inline

Return the output setting, represented as 0 or 1 (int)

Returns: Non zero value if pin is connected to uc GPIO 0 if gpio object was initialized with NC

void mbed::DigitalInOut::mode ( PinMode pull )

inline

Set the input pin mode

Parameters

pull	PullUp, PullDown, PullNone, OpenDrain

mbed::DigitalInOut::operator int ( )

inline

A shorthand for read()

See also: DigitalInOut::read()

DigitalInOut& mbed::DigitalInOut::operator= ( int value )

inline

A shorthand for write()

See also: DigitalInOut::write()

DigitalInOut& mbed::DigitalInOut::operator= ( DigitalInOut & rhs )

inline

A shorthand for write()

See also: DigitalInOut::write()

void mbed::DigitalInOut::output ( )

inline

Set as an output

int mbed::DigitalInOut::read ( )

inline

Return the output setting, represented as 0 or 1 (int)

Returns: an integer representing the output setting of the pin if it is an output, or read the input if set as an input

void mbed::DigitalInOut::write ( int value )

inline

Set the output, specified as 0 or 1 (int)

Parameters

value An integer specifying the pin output value, 0 for logical 0, 1 (or any other non-zero value) for logical 1
