Struct rust_gpiozero::output_devices::PWMLED

pub struct PWMLED(_);

Represents a light emitting diode (LED) with variable brightness. A typical configuration of such a device is to connect a GPIO pin to the anode (long leg) of the LED, and the cathode (short leg) to ground, with an optional resistor to prevent the LED from burning out.

Methods

impl PWMLED

pub fn new(pin: u8) -> PWMLED

Returns a PMWLED with the pin number given

• pin - The GPIO pin which the device is attached to

pub fn blink(
    &mut self,
    on_time: f32,
    off_time: f32,
    fade_in_time: f32,
    fade_out_time: f32
)

Make the device turn on and off repeatedly

• on_time - Number of seconds on
• off_time - Number of seconds off
• fade_in_time - Number of seconds to spend fading in
• fade_out_time - Number of seconds to spend fading out

pub fn on(&mut self)

Turns the device on.

pub fn off(&mut self)

Turns the device off.

pub fn pulse(&mut self, fade_in_time: f32, fade_out_time: f32)

Make the device fade in and out repeatedly.

• fade_in_time - Number of seconds to spend fading in
• fade_out_time - Number of seconds to spend fading out

pub fn set_value(&mut self, value: f64)

Set the duty cycle of the PWM device. 0.0 is off, 1.0 is fully on. Values in between may be specified for varying levels of power in the device.

pub fn set_blink_count(&mut self, n: i32)

Set the number of times to blink the device

• n - Number of times to blink
