Public Types

enum  Direction { In = 0, Out = 1, InOut = 2, Special = 3 }
 Declares the direction of a GPIO.
 

Static Public Member Functions

static void setInput ()
 configure pin as input
 
static bool read ()
 read input
 

Static Public Attributes

static constexpr Direction direction = Direction::In
 Declares the Pin direction.
 
static constexpr bool High = true
 
static constexpr bool Low = false
 

Detailed Description

Input interface of an I/O pin.

The pin is not automatically set as an input after startup, so remember to call setInput() after startup!

Member Data Documentation

constexpr bool modm::Gpio::Low = false
