Constructor & Destructor Documentation

PinIO()

PinIO::PinIO ( )

inline

Create a PinIO object with no assigned pin.

Definition at line 44 of file PinIO.h.

Member Function Documentation

__attribute__() [1/10]

PinIO::__attribute__ ( (always_inline)  )

inline

Returns

Pin's level

Definition at line 50 of file PinIO.h.

__attribute__() [2/10]

PinIO::__attribute__ ( (always_inline)  )

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 129 of file PinIO.h.

__attribute__() [3/10]

PinIO::__attribute__ ( (always_inline)  )

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 73 of file PinIO.h.

__attribute__() [4/10]

PinIO::__attribute__ ( (always_inline)  )

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 143 of file PinIO.h.

__attribute__() [5/10]

PinIO::__attribute__ ( (always_inline)  )

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 84 of file PinIO.h.

__attribute__() [6/10]

PinIO::__attribute__ ( (always_inline)  )

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.

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

Definition at line 162 of file PinIO.h.

__attribute__() [7/10]

PinIO::__attribute__ ( (always_inline)  )

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.

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

Definition at line 99 of file PinIO.h.

__attribute__() [8/10]

PinIO::__attribute__ ( (always_inline)  )

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 61 of file PinIO.h.

__attribute__() [9/10]

PinIO::__attribute__ ( (always_inline)  )

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 178 of file PinIO.h.

__attribute__() [10/10]

PinIO::__attribute__ ( (always_inline)  )

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.
