Enum stm32wlxx_hal::info::Core

pub enum Core {
    Cm4,
    Cm0p,
}

CPU core.

Variants

Cm4

Cortex-M4, core 1.

Cm0p

Cortex-M0+, core 2.

Implementations

impl Core

pub const CT: Core = Core::Cm4

Get the CPU core at compile time.

This is determined by the HAL features.

For a runtime mechanism use Core::from_cpuid().

Example

use stm32wlxx_hal::info::Core;

#[cfg(feature = "stm32wl5x_cm4")]
assert_eq!(Core::CT, Core::Cm4);

#[cfg(feature = "stm32wl5x_cm0p")]
assert_eq!(Core::CT, Core::Cm0p);

#[cfg(feature = "stm32wle5")]
assert_eq!(Core::CT, Core::Cm4);

pub fn from_cpuid() -> Core

Get the CPU core at runtime.

This is determined by the part number field in CPUID register in the system control block.

For a compile time mechanism use Core::CT.

Example

use stm32wlxx_hal::info::Core;

match Core::from_device() {
    Core::Cm4 => defmt::info!("Hello world from the Cortex-M4 CPU"),
    Core::Cm0p => defmt::info!("Hello world from the Cortex-M0+ CPU"),
}

pub const fn is_cm4(&self) -> bool

Returns true if the core is Cm4.

pub const fn is_cm0p(&self) -> bool

Returns true if the core is Cm0p.

Trait Implementations

impl Clone for Core

fn clone(&self) -> Core

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Core

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Core

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Core

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Core

fn eq(&self, other: &Core) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
