Struct Analog 

pub struct Analog<P> { /* private fields */ }

Analog pin

Implementations

impl<P> Analog<P>

where P: PinOps + AdcCh,

pub const ADC_CH: Ch = P::ADC_CH

Analog to digital converter channel.

pub fn new(pin: P, cs: &CriticalSection) -> Self

Create a new analog pin from a GPIO.

Example

Configure GPIO B14 as an analog pin (ADC_IN1).

use stm32wlxx_hal::{
    gpio::{pins, Analog, PortB},
    pac,
};

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

let gpiob: PortB = PortB::split(dp.GPIOB, &mut dp.RCC);
let mut b14: Analog<pins::B14> = cortex_m::interrupt::free(|cs| Analog::new(gpiob.b14, cs));

pub fn free(self) -> P

Free the GPIO pin.

Example

Configure a GPIO as an analog pin, then free it.

use stm32wlxx_hal::{
    gpio::{pins, Analog, PortB},
    pac,
};

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

let gpiob: PortB = PortB::split(dp.GPIOB, &mut dp.RCC);
let b14: Analog<pins::B14> = cortex_m::interrupt::free(|cs| Analog::new(gpiob.b14, cs));
let b14: pins::B14 = b14.free();
