Pin

The ::picolibrary::Microchip::megaAVR::GPIO::Pin class is used to interact with a Microchip megaAVR microcontroller pin.

• To check if a pin is associated with a GPIO port, use the bool conversion operator.
• To configure a pin to act as an internally pulled-up input, use the ::picolibrary::Microchip::megaAVR::GPIO::Pin::configure_pin_as_internally_pulled_up_input() member function.
• To configure a pin to act as an open-drain I/O pin, use the ::picolibrary::Microchip::megaAVR::GPIO::Pin::configure_pin_as_open_drain_io() member function.
• To configure a pin to act as a push-pull I/O pin, use the ::picolibrary::Microchip::megaAVR::GPIO::Pin::configure_pin_as_push_pull_io() member function.
• To check if an internally pulled-up input pin’s internal pull-up resistor is disabled, use the ::picolibrary::Microchip::megaAVR::GPIO::Pin::pull_up_is_disabled() member function.
• To check if an internally pulled-up input pin’s internal pull-up resistor is enabled, use the ::picolibrary::Microchip::megaAVR::GPIO::Pin::pull_up_is_enabled() member function.
• To disable an internally pulled-up input pin’s internal pull-up resistor, use the ::picolibrary::Microchip::megaAVR::GPIO::Pin::disable_pull_up() member function.
• To enable an internally pulled-up input pin’s internal pull-up resistor, use the ::picolibrary::Microchip::megaAVR::GPIO::Pin::enable_pull_up() member function.
• To check if a pin is in the low state, use the ::picolibrary::Microchip::megaAVR::GPIO::Pin::is_low() member function.
• To check if a pin is in the high state, use the ::picolibrary::Microchip::megaAVR::GPIO::Pin::is_high() member function.
• To transition an open-drain I/O pin to the low state, use the ::picolibrary::Microchip::megaAVR::GPIO::Pin::transition_open_drain_io_to_low() member function.
• To transition a push-pull I/O pin to the low state, use the ::picolibrary::Microchip::megaAVR::GPIO::Pin::transition_push_pull_io_to_low() member function.
• To transition an open-drain I/O pin to the high state, use the ::picolibrary::Microchip::megaAVR::GPIO::Pin::transition_open_drain_io_to_high() member function.
• To transition a push-pull I/O pin to the high state, use the ::picolibrary::Microchip::megaAVR::GPIO::Pin::transition_push_pull_io_to_high() member function.
• To toggle the state of an open-drain I/O pin, use the ::picolibrary::Microchip::megaAVR::GPIO::Pin::toggle_open_drain_io() member function.
• To toggle the state of a push-pull I/O pin, use the ::picolibrary::Microchip::megaAVR::GPIO::Pin::toggle_push_pull_io() member function.

Internally Pulled-Up Input Pin

The ::picolibrary::Microchip::megaAVR::GPIO::Internally_Pulled_Up_Input_Pin class implements a GPIO internally pulled-up input pin interface for interacting with a Microchip megaAVR microcontroller pin. See the ::picolibrary::GPIO::Internally_Pulled_Up_Input_Pin_Concept documentation for more information. The ::picolibrary::Microchip::megaAVR::GPIO::Internally_Pulled_Up_Input_Pin state interactive test is defined in the test/interactive/picolibrary/microchip/megaavr/gpio/internally_pulled_up_input_pin/state/main.cc source file.

Open-Drain I/O Pin

The ::picolibrary::Microchip::megaAVR::GPIO::Open_Drain_IO_Pin class implements a GPIO open-drain I/O pin interface for interacting with a Microchip megaAVR microcontroller pin. See the ::picolibrary::GPIO::IO_Pin_Concept documentation for more information. The ::picolibrary::Microchip::megaAVR::GPIO::Open_Drain_IO_Pin toggle interactive test is defined in the test/interactive/picolibrary/microchip/megaavr/gpio/open_drain_io_pin/toggle/main.cc source file.

Push-Pull I/O Pin

The ::picolibrary::Microchip::megaAVR::GPIO::Push_Pull_IO_Pin class implements a GPIO push-pull I/O pin interface for interacting with a Microchip megaAVR microcontroller pin. See the ::picolibrary::GPIO::IO_Pin_Concept documentation for more information. The ::picolibrary::Microchip::megaAVR::GPIO::Push_Pull_IO_Pin toggle interactive test is defined in the test/interactive/picolibrary/microchip/megaavr/gpio/push_pull_io_pin/toggle/main.cc source file.
