Typedef Documentation

specialFunction

using embvm::gpio::specialFunction = typedef embvm::gpio::base<embvm::gpio::direction::special>

Alias for inheriting from gpio::base with a special function pin.

Enumeration Type Documentation

direction

enum embvm::gpio::direction

strong

GPIO direction configuration options.

Enumerator
in	GPIO input.
out	GPIO output.
inout	GPIO input-output.
special	Configure this pin in special-purpose mode. e.g. non-standard IO mode such as PWM, SPI CS line

pull

enum embvm::gpio::pull

strong

GPIO internal pull configuration options.

This enumeration represents the configuration options for a GPIO's internal pull settings.

External pull-ups or pull-downs may still be used if gpio::pull::none is selected.

Enumerator
none	No internal pull option is used.
pullup	Internal pull-up is configured.
pulldown	Internal pull-down is enabled.
