Struct DedicatedGpioOutput 

pub struct DedicatedGpioOutput<'lt> { /* private fields */ }

A dedicated GPIO output driver.

Due to how the hardware works, DedicatedGpioOutput can drive any number of GPIO pins. Use DedicatedGpioOutput::new to create a driver, then DedicatedGpioOutput::with_pin to add output drivers.

Examples

use esp_hal::gpio::{
    Level,
    Output,
    OutputConfig,
    dedicated::{DedicatedGpio, DedicatedGpioOutput},
};

// Create a dedicated GPIO driver:
let channels = DedicatedGpio::new(peripherals.GPIO_DEDICATED);
let dedicated_output = DedicatedGpioOutput::new(channels.channel0);

// Add any number of output pin drivers:
let output = Output::new(peripherals.GPIO0, Level::Low, OutputConfig::default());
let mut dedicated_output = dedicated_output.with_pin(output);

// Now you can use the pin.
dedicated_output.set_level(Level::High);

Implementations

impl<'lt> DedicatedGpioOutput<'lt>

pub fn new<CH>(channel: CH) -> Self

where CH: OutputChannel + 'lt,

Creates a new dedicated GPIO output driver.

Returns an empty driver. Output drivers must be added with the Self::with_pin method.

pub fn with_pin(self, pin: impl OutputDriver + 'lt) -> Self

Adds a GPIO output pin to this dedicated GPIO output.

A dedicated GPIO output can drive any number of GPIO pins. The driver releases the pins when it is dropped.

The GPIO matrix routes the current output of the dedicated GPIO channel to the pin. The pin follows the channel level immediately. The GPIO output register of the pin does not change.

pub fn set_level(&mut self, level: Level)

Changes the current state of the GPIO pins.

pub fn output_level(&self) -> Level

Returns the current output state of the GPIO pins.

Returns Level::High if any of the GPIO pins are set high, otherwise Level::Low.

Trait Implementations

impl Drop for DedicatedGpioOutput<'_>

Available on crate feature unstable only.

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl ErrorType for DedicatedGpioOutput<'_>

Available on crate feature unstable only.

type Error = !

Error type

impl OutputPin for DedicatedGpioOutput<'_>

Available on crate feature unstable only.

fn set_low(&mut self) -> Result<(), Self::Error>

Drives the pin low.

fn set_high(&mut self) -> Result<(), Self::Error>

Drives the pin high.

fn set_state(&mut self, state: PinState) -> Result<(), Self::Error>

Drives the pin high or low depending on the provided value.
