Struct stm32_hal2::gpio::GpioCPin

pub struct GpioCPin {
    pub port: PortLetter,
    pub pin: PinNum,
}

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: PinNum
