Module rmicrobit::gpio

Support for the GPIO peripheral.

The types in this module provide structured access to the micro:bit's GPIO pins, organised in functional groups.

This system supports working with different devices without having to manage a shared reference to the single GPIO peripheral.

The structs don't hold any data at runtime; they exist to manage ownership of the pins.

Use GPIO.split_by_kind() to retrieve one instance of each XxxPins type.

Example

use rmicrobit::prelude::*;
use rmicrobit::gpio::PinsByKind;
let p: nrf51::Peripherals = _;
let PinsByKind {display_pins, button_pins, ..} = p.GPIO.split_by_kind();

Structs

ButtonPins	The GPIO pins connected to the micro:bit's user buttons.
DisplayPins	The GPIO pins connected to the micro:bit's LED display.
EdgeConnectorPins	The GPIO pins available on the edge connector and not otherwise connected.
I2cPins	The GPIO pins used for the micro:bit's I2C interface.
OtherPins	The remaining GPIO pins.
PinsByKind	The micro:bit's GPIO pins, organised in functional groups.
SerialPins	The GPIO pins connected to the micro:bit's USB serial port.

Traits
