Pin

::picolibrary::Microchip::megaAVR0::GPIO::Pin template class specializations provide a mostly common interface for interacting with a Microchip megaAVR 0-series microcontroller pin using either a PORT peripheral or a VPORT peripheral. The ::picolibrary::Microchip::megaAVR0::GPIO::Pin<::picolibrary::Microchip::megaAVR0::Peripheral::PORT> specialization implements this interface using a PORT peripheral. The ::picolibrary::Microchip::megaAVR0::GPIO::Pin<::picolibrary::Microchip::megaAVR0::Peripheral::VPORT> specialization implements this interface using a VPORT peripheral.

• To check if a pin is associated with a GPIO port or virtual port, use the bool conversion operator.
• To configure a pin to act as an input, use the ::picolibrary::Microchip::megaAVR0::GPIO::Pin::configure_pin_as_input() member function.
• To configure a pin to act as an internally pulled-up input, use the ::picolibrary::Microchip::megaAVR0::GPIO::Pin<::picolibrary::Microchip::megaAVR0::Peripheral::PORT>::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::megaAVR0::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::megaAVR0::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::megaAVR0::GPIO::Pin<::picolibrary::Microchip::megaAVR0::Peripheral::PORT>::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::megaAVR0::GPIO::Pin<::picolibrary::Microchip::megaAVR0::Peripheral::PORT>::pull_up_is_enabled() member function.
• To disable an internally pulled-up input pin’s internal pull-up resistor, use the ::picolibrary::Microchip::megaAVR0::GPIO::Pin<::picolibrary::Microchip::megaAVR0::Peripheral::PORT>::disable_pull_up() member function.
• To enable an internally pulled-up input pin’s internal pull-up resistor, use the ::picolibrary::Microchip::megaAVR0::GPIO::Pin<::picolibrary::Microchip::megaAVR0::Peripheral::PORT>::enable_pull_up() member function.
• To check if a pin is in the low state, use the ::picolibrary::Microchip::megaAVR0::GPIO::Pin::is_low() member function.
• To check if a pin is in the high state, use the ::picolibrary::Microchip::megaAVR0::GPIO::Pin::is_high() member function.
• To transition an open-drain I/O pin to the low state, use the ::picolibrary::Microchip::megaAVR0::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::megaAVR0::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::megaAVR0::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::megaAVR0::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::megaAVR0::GPIO::Pin::toggle_open_drain_io() member function.
• To toggle the state of a push-pull I/O pin, use the ::picolibrary::Microchip::megaAVR0::GPIO::Pin::toggle_push_pull_io() member function.
