Struct Crc 

pub struct Crc {}

Constrained CRC peripheral.

Implementations

impl Crc

pub fn reset(&mut self)

This will reset the CRC to its initial condition.

pub fn reset_with_inital_value(&mut self, initial_value: u32)

This will reset the CRC to its initial condition, however with a specific initial value. This is very useful if many task are sharing the CRC peripheral, as one can read out the intermediate result, store it until the next time a task runs, and initialize with the intermediate result to continue where the task left off.

pub fn feed(&mut self, data: &[u8])

Feed the CRC with data

pub fn result(&mut self) -> u32

Get the result of the CRC, depending on the polynomial chosen only a certain amount of the bits are the result. This will reset the CRC peripheral after use.

pub fn peek_result(&self) -> u32

Get a peed at the result of the CRC, depending on the polynomial chosen only a certain amount of the bits are the result.
