Struct microbit::hal::nvmc::Nvmc

pub struct Nvmc<T> where
    T: Instance,  { /* private fields */ }

Interface to an NVMC instance.

Implementations

impl<T> Nvmc<T> where
    T: Instance, 

pub fn new(nvmc: T, storage: &'static mut [u32]) -> Nvmc<T>

Takes ownership of the peripheral and storage area.

pub fn free(self) -> (T, &'static mut [u32])

Consumes self and returns back the raw peripheral and associated storage.

Trait Implementations

impl<T> NorFlash for Nvmc<T> where
    T: Instance, 

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<(), <Nvmc<T> as ReadNorFlash>::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<(), <Nvmc<T> as ReadNorFlash>::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. offset and bytes.len() must both be multiples of WRITE_SIZE.

impl<T> ReadNorFlash for Nvmc<T> where
    T: Instance, 

type Error = NvmcError

An enumeration of storage errors

const READ_SIZE: usize = 4usize

The minumum number of bytes the storage peripheral can read

fn read(
    &mut self,
    offset: u32,
    bytes: &mut [u8]
) -> Result<(), <Nvmc<T> as ReadNorFlash>::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.
