Struct embassy_nrf::nvmc::Nvmc

pub struct Nvmc<'d> { /* private fields */ }

Non-Volatile Memory Controller (NVMC) that implements the embedded-storage traits.

Implementations

impl<'d> Nvmc<'d>

pub fn new(_p: impl Peripheral<P = NVMC> + 'd) -> Self

Create Nvmc driver.

Trait Implementations

impl<'d> ErrorType for Nvmc<'d>

type Error = Error

Errors returned by this NOR flash.

impl<'d> NorFlash for Nvmc<'d>

const WRITE_SIZE: usize = 4usize

The minumum number of bytes the storage peripheral can write

const ERASE_SIZE: usize = 4_096usize

The minumum number of bytes the storage peripheral can erase

fn erase(&mut self, from: u32, to: u32) -> Result<(), Self::Error>

Erase the given storage range, clearing all data within [from..to]. The given range will contain all 1s afterwards.

fn write(&mut self, offset: u32, bytes: &[u8]) -> Result<(), Self::Error>

If power is lost during write, the contents of the written words are undefined, but the rest of the page is guaranteed to be unchanged. It is not allowed to write to the same word twice.

impl<'d> ReadNorFlash for Nvmc<'d>

const READ_SIZE: usize = 1usize

The minumum number of bytes the storage peripheral can read

fn read(&mut self, offset: u32, bytes: &mut [u8]) -> Result<(), Self::Error>

Read a slice of data from the storage peripheral, starting the read operation at the given address offset, and reading bytes.len() bytes.

fn capacity(&self) -> usize

The capacity of the peripheral in bytes.
