Struct stm32_hal2::gpio::GpioBPin

pub struct GpioBPin {
    pub port: PortLetter,
    pub pin: u8,
}

Represents a single GPIO pin. Provides methods that, when passed a mutable reference to its port’s register block, can change and read various properties of the pin.

Fields

port: PortLetter

pin: u8

Implementations

impl GpioBPin

pub fn enable_interrupt(
    &mut self,
    edge: Edge,
    exti: &mut EXTI,
    syscfg: &mut SYSCFG
)

pub fn is_high(&self) -> bool

Check if the pin’s input voltage is high (VCC).

pub fn is_low(&self) -> bool

Check if the pin’s input voltage is low (ground).

pub fn set_high(&mut self)

Set the pin’s output voltage to high (VCC).

pub fn set_low(&mut self)

Set the pin’s output voltage to ground (low).
