Struct stm32wlxx_hal::info::Uid64

pub struct Uid64 { /* private fields */ }

IEEE 64-bit unique device ID (UID64).

Note: There are two UIDs, the other is Uid.

Implementations

impl Uid64

pub const PTR: *const u32 = {0x1fff7580 as *const u32}

Pointer to the IEEE 64-bit unique device ID (UID64) device memory.

pub fn from_device() -> Self

Get the IEEE 64-bit unique device ID (UID64) from device memory.

Example

use stm32wlxx_hal::info;

let uid64: info::Uid64 = info::Uid64::from_device();
assert_eq!(uid64.dev_id(), 0x15);
assert_eq!(uid64.company_id(), 0x0080E1);
// uid64.devnum() is unique

pub const fn devnum(&self) -> u32

Unique 32-bit device number.

This is sequential and unique for each individual device.

Example

use stm32wlxx_hal::info::Uid64;

let devnum: u32 = Uid64::from_device().devnum();

pub fn read_devnum() -> u32

Read the 32-bit device number from device memory.

This is provided for applications that only need the 32-bit device number, performing a single device memory read.

Example

use stm32wlxx_hal::info::Uid64;

let devnum: u32 = Uid64::read_devnum();
assert_eq!(devnum, Uid64::from_device().devnum());

pub const fn company_id(&self) -> u32

Company ID

This is 0x0080E1 for STMicroelectronics.

Note: Only the first 24 bits are used.

Example

use stm32wlxx_hal::info::Uid64;

assert_eq!(Uid64::from_device().company_id(), 0x0080E1);

pub const fn dev_id(&self) -> u8

Device ID

This is always 0x15 for this device.

Example

use stm32wlxx_hal::info::Uid64;

assert_eq!(Uid64::from_device().dev_id(), 0x15);

Trait Implementations

impl Clone for Uid64

fn clone(&self) -> Uid64

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Uid64

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

Formats the value using the given formatter.

impl Display for Uid64

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

Formats the value using the given formatter.

impl From<Uid64> for u64

fn from(uid: Uid64) -> Self

Converts to this type from the input type.

impl From<u64> for Uid64

fn from(uid: u64) -> Self

Converts to this type from the input type.

impl Hash for Uid64

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 Uid64

fn eq(&self, other: &Uid64) -> 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.
