Detailed Description

Dummy implementation of an I/O pin.

This class can be used when a pin is not required. All functions are dummy functions which do nothing. read() will always return false.

For example when creating a software SPI with the modm::SoftwareSimpleSpi class and the return channel (MISO - Master In Slave Out) is not needed, a good way is to use this class as a parameter when defining the SPI class.

Example:

#include <modm/architecture/platform.hpp>
namespace pin
{
typedef GpioOutputD7 Clk;
typedef GpioOutputD5 Mosi;
}
modm::SoftwareSpiMaster< pin::Clk, pin::Mosi, GpioUnused > Spi;
...
Spi::write(0xaa);

Member Function Documentation

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

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.

constexpr bool modm::Gpio::Low = false
