Module gpio

GPIO Driver

Provides a hardware abstraction layer for General Purpose Input/Output (GPIO) pins on STM32 microcontrollers.

This module defines the GPIO trait and supporting types for pin configuration, interrupt handling, and digital I/O operations across different STM32 families.

Structs

EventType

Represents GPIO interrupt events.

Enums

Direction

Defines the direction of a GPIO pin.

EventTrigger

Defines the trigger condition for an external interrupt.

OutputMode

Defines the output mode of a GPIO pin.

PullResistor

Defines the internal pull-up or pull-down resistor configuration.

Traits

Gpio

A trait that defines a standard interface for a GPIO driver. This trait manages a collection of GPIO pins.

Type Aliases

Error

A generic error type for the GPIO driver, using i32 for error codes.

Pin

Represents a GPIO pin identifier. The interpretation of this identifier is implementation-specific. For example, it could be a simple number (0-15) for a single port, or a value like (port << 4) | pin for multiple ports.

Result

A specialized Result type for GPIO operations.
