Constructor & Destructor Documentation

PinIO::PinIO ( )

inline

Create a PinIO object with no assigned pin.

Definition at line 41 of file PinIO.h.

Member Function Documentation

void PinIO::high ( )

inline

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

This function will enable interrupts. This function should not be called in an ISR or where interrupts are disabled.

Definition at line 108 of file PinIO.h.

void PinIO::highI ( )

inline

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

This function must be called with interrupts disabled. This function will not change the interrupt state.

Definition at line 65 of file PinIO.h.

void PinIO::low ( )

inline

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

This function will enable interrupts. This function should not be called in an ISR or where interrupts are disabled.

Definition at line 116 of file PinIO.h.

void PinIO::lowI ( )

inline

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

This function must be called with interrupts disabled. This function will not change the interrupt state.

Definition at line 73 of file PinIO.h.

void PinIO::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 pullup for input mode.

This function will enable interrupts. This function should not be called in an ISR or where interrupts are disabled.

Definition at line 127 of file PinIO.h.

void PinIO::modeI ( bool  mode )

inline

Set pin mode

Parameters

[in]

mode

if true set output mode else input mode.

mode() does not enable or disable the 20K pullup for input mode.

This function must be called with interrupts disabled. This function will not change the interrupt state.

Definition at line 84 of file PinIO.h.

bool PinIO::read ( )

inline

Returns

Pin's level

Definition at line 48 of file PinIO.h.

void PinIO::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.

Definition at line 56 of file PinIO.h.

void PinIO::write ( bool  level )

inline

Write pin.

Parameters

[in]

level

If output mode set pin high if true else low. If input mode enable 20K pullup if true else disable pullup.

This function will enable interrupts. This function should not be called in an ISR or where interrupts are disabled.

Definition at line 137 of file PinIO.h.

void PinIO::writeI ( bool  level )

inline

Write pin.

Parameters

[in]

level

If output mode set pin high if true else low. If input mode enable 20K pullup if true else disable pullup.

This function must be called with interrupts disabled. This function will not change the interrupt state.
