Variable pinConst

Type Declaration

• invert: function

  • invert(level: PinLevel): PinLevel

    Returns the opposite level.

    Parameters

    • level: PinLevel

      The level to invert.

    Returns PinLevel

    The other level.

• isAsserted: function

  • isAsserted(polarity: PinPolarity, level: PinLevel): boolean

    Reports whether a physical level means the signal is asserted.

    Parameters

    • polarity: PinPolarity

      How the signal is wired.

    • level: PinLevel

      The level read on the pin.

    Returns boolean

    Whether the signal is asserted.

• levelFor: function

  • levelFor(polarity: PinPolarity, asserted: boolean): PinLevel

    Returns the physical level that represents a logical state.

    Parameters

    • polarity: PinPolarity

      How the signal is wired.

    • asserted: boolean

      Whether the signal should be asserted.

    Returns PinLevel

    The level to drive, inverted for active-low wiring.

• levelFrom: function

  • levelFrom(high: boolean): PinLevel

    Returns the level a boolean names.

    Parameters

    • high: boolean

      true for high, false for low.

    Returns PinLevel

    The level.

• triggers: function

  • triggers(edge: PinEdge, from: PinLevel, to: PinLevel): boolean

    Reports whether a transition fires an interrupt trigger.

    Parameters

    • edge: PinEdge

      The trigger configured on the pin.

    • from: PinLevel

      The level before the change.

    • to: PinLevel

      The level after it.

    Returns boolean

    Whether the trigger fires.
