Module gpio 

GPIO control for oveRTOS.

Provides pin configuration, digital read/write, and interrupt registration. Pins are identified by a GpioPin which bundles the port and pin number, preventing accidental argument swaps.

Structs

GpioPin

A GPIO pin identified by port and pin number.

InputPin

Fixed-mode input GPIO pin.

OutputPin

Fixed-mode output GPIO pin.

Enums

GpioIrqMode

GPIO interrupt trigger mode.

GpioMode

GPIO pin direction/pull mode.

Functions

configure

Configure a GPIO pin’s direction and pull mode.

get

Read a GPIO pin input value. Returns the pin level (0 or 1) on success.

irq_disable

Disable a registered GPIO interrupt without removing the registration.

irq_enable

Enable a previously registered GPIO interrupt.

irq_register^⚠

Register a GPIO interrupt callback.

set

Set a GPIO pin’s output level (value: 0 = low, non-zero = high).
