Struct D0 

pub struct D0 { /* private fields */ }

Push-button D0.

Implementations

impl D0

pub fn new(a0: A0, cs: &CriticalSection) -> Self

Create a new push-button D0.

Example

use lora_e5_bsp::{
    hal::{cortex_m, gpio::PortA, pac},
    pb::{PushButton, D0},
};

let mut dp: pac::Peripherals = pac::Peripherals::take().unwrap();

let gpioa: PortA = PortA::split(dp.GPIOA, &mut dp.RCC);
let d0 = cortex_m::interrupt::free(|cs| D0::new(gpioa.a0, cs));

pub fn free(self) -> A0

Free the GPIO pin from the push-button struct.

Example

use lora_e5_bsp::{
    hal::{cortex_m, gpio::PortA, pac},
    pb::{PushButton, D0},
};

let mut dp: pac::Peripherals = pac::Peripherals::take().unwrap();

let gpioa: PortA = PortA::split(dp.GPIOA, &mut dp.RCC);
let d0 = cortex_m::interrupt::free(|cs| D0::new(gpioa.a0, cs));
// ... use push button
let c0 = d0.free();

pub unsafe fn steal() -> Self

Steal the push-button from whatever is currently using it.

Safety

1. Ensure that the code stealing the push-button has exclusive access to the underlying GPIO. Singleton checks are bypassed with this method.
2. You are responsible for setting up the underlying GPIO correctly. No setup will occur when using this method.

Example

use lora_e5_bsp::pb::D0;

// ... setup happens here

let d0: D0 = unsafe { D0::steal() };
