Struct Flash 

pub struct Flash<const PAGE_SIZE: usize, const PAGE_NUM: usize, const MINI_WRITE_SIZE: usize = 4, const MINI_READ_SIZE: usize = 1, MODE = Blocking> { /* private fields */ }

Internal flash memory driver.

Implementations

impl<const PAGE_SIZE: usize, const PAGE_NUM: usize, const MINI_WRITE_SIZE: usize, const MINI_READ_SIZE: usize> Flash<PAGE_SIZE, PAGE_NUM, MINI_WRITE_SIZE, MINI_READ_SIZE, Blocking>

pub fn new_blocking() -> Self

Create a new flash driver, usable in blocking mode.

impl<const PAGE_SIZE: usize, const PAGE_NUM: usize, const MINI_WRITE_SIZE: usize, const MINI_READ_SIZE: usize, MODE> Flash<PAGE_SIZE, PAGE_NUM, MINI_WRITE_SIZE, MINI_READ_SIZE, 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.

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<const PAGE_SIZE: usize, const PAGE_NUM: usize, const MINI_WRITE_SIZE: usize, const MINI_READ_SIZE: usize, MODE> ErrorType for Flash<PAGE_SIZE, PAGE_NUM, MINI_WRITE_SIZE, MINI_READ_SIZE, MODE>

type Error = Error

Errors returned by this NOR flash.

impl<const PAGE_SIZE: usize, const PAGE_NUM: usize, const MINI_WRITE_SIZE: usize, const MINI_READ_SIZE: usize, MODE> NorFlash for Flash<PAGE_SIZE, PAGE_NUM, MINI_WRITE_SIZE, MINI_READ_SIZE, MODE>

const WRITE_SIZE: usize = MINI_WRITE_SIZE

The minumum number of bytes the storage peripheral can write

const ERASE_SIZE: usize = PAGE_SIZE

The minumum number of bytes the storage peripheral can erase

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.

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<const PAGE_SIZE: usize, const PAGE_NUM: usize, const MINI_WRITE_SIZE: usize, const MINI_READ_SIZE: usize, MODE> ReadNorFlash for Flash<PAGE_SIZE, PAGE_NUM, MINI_WRITE_SIZE, MINI_READ_SIZE, MODE>

const READ_SIZE: usize = MINI_READ_SIZE

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.
