Implementations

impl Bank1Region2<'_, Async>

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

Async read.

Note: reading from flash can’t actually block, so this is the same as blocking_read.

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

Async write.

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

Async erase.

impl<MODE> Bank1Region2<'_, MODE>

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

Blocking read.

NOTE: offset is an offset from the flash start, NOT an absolute address. For example, to read address 0x0800_1234 you have to use offset 0x1234.

impl Bank1Region2<'_, Blocking>

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

Blocking write.

NOTE: offset is an offset from the flash start, NOT an absolute address. For example, to write address 0x0800_1234 you have to use offset 0x1234.

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

Blocking erase.

NOTE: from and to are offsets from the flash start, NOT an absolute address. For example, to erase address 0x0801_0000 you have to use offset 0x1_0000.

Trait Implementations

impl<MODE> ErrorType for Bank1Region2<'_, MODE>

type Error = Error

Errors returned by this NOR flash.

impl NorFlash for Bank1Region2<'_, Async>

const WRITE_SIZE: usize = 4usize

The minumum number of bytes the storage peripheral can write

const ERASE_SIZE: usize = 65_536usize

The minumum number of bytes the storage peripheral can erase

async 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.

async 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.

impl NorFlash for Bank1Region2<'_, Blocking>

const WRITE_SIZE: usize = 4usize

The minumum number of bytes the storage peripheral can write

const ERASE_SIZE: usize = 65_536usize

The minumum number of bytes the storage peripheral can erase

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

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.

impl ReadNorFlash for Bank1Region2<'_, Async>

const READ_SIZE: usize = 1usize

The minumum number of bytes the storage peripheral can read

async 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.

impl<MODE> ReadNorFlash for Bank1Region2<'_, MODE>

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.
