[][src]Module trinket_m0::gpio

Working with GPIO pins. The pins are associated with the PORT hardware. This module defines a split method on the PORT type that is used to safely reference the individual pin configuration. The IO pins can be switched into alternate function modes, which routes the pins to different peripherals depending on the mode for the pin. The pin configuration is reflected through the use of type states to make the interface (ideally, or at least practically) impossible to misuse.

Traits

GpioExt

The GpioExt trait allows splitting the PORT hardware into its constituent pin parts.

IntoFunction

A trait that makes it easier to generically manage converting a pin from its current state into some other functional mode. The configuration change requires exclusive access to the Port hardware, which is why this isn't simply the standard Into trait.
