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

Detailed Description

Output interface of an I/O pin.

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

Member Function Documentation

static bool modm::GpioOutput::isSet ( )
static

Returns the set logical output state of the pin. This may be different from the physical state!

Member Data Documentation

constexpr bool modm::Gpio::Low = false
inheritedstaticconstexpr

These constants refer to the logical state of the GPIO. The physical state is determined by the configuration and external connection.
