Led

zephyr::device::led

Struct Led 

Source 
pub struct Led { /* private fields */ }
Expand description

A single logical LED exposed by a Zephyr LED controller.

This wrapper maps to Zephyr’s led_* API. Devicetree child nodes of a pwm-leds controller become instances of this type.

Implementations§

Source§

impl Led

Source

pub fn is_ready(&self) -> bool

Verify that the underlying LED controller is ready for use.

Source

pub fn set_brightness(&mut self, value: u8) -> Result<()>

Set the LED brightness as a percentage in the range 0..=100.

Source

pub fn on(&mut self) -> Result<()>

Turn the LED fully on.

Source

pub fn off(&mut self) -> Result<()>

Turn the LED fully off.

Blink the LED using millisecond delays.
