Struct Eeprom 

pub struct Eeprom<'d, M: Mode> { /* private fields */ }

Driver for the data EEPROM.

The EEPROM is written without erasing it first, at any offset and with any length. The hardware erases and programs it in 32-bit words, which takes a few milliseconds per word: a write rewrites every word it touches, except the ones that already have the value written. While a word is programmed, the CPU stalls when it reads from the flash bank being written.

Erased EEPROM reads as 0x00.

Implementations

impl<'d, M: Mode> Eeprom<'d, M>

pub fn capacity(&self) -> usize

Size of the EEPROM in bytes, EEPROM_SIZE.

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

Blocking read.

NOTE: offset is an offset from the start of the EEPROM, EEPROM_BASE.

impl<'d> Eeprom<'d, Blocking>

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

Blocking write.

NOTE: offset is an offset from the start of the EEPROM, EEPROM_BASE.

impl<'d> Eeprom<'d, Async>

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

Async read.

Note: reading from the EEPROM 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.

NOTE: offset is an offset from the start of the EEPROM, EEPROM_BASE.

Trait Implementations

impl<M: Mode> ReadStorage for Eeprom<'_, M>

type Error = Error

An enumeration of storage errors

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 storage peripheral in bytes.

impl Storage for Eeprom<'_, Blocking>

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

Write a slice of data to the storage peripheral, starting the write operation at the given address offset (between 0 and self.capacity()).
