[−][src]Module gemma_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 |
